Description

Ring-type biosignal collection device

[0001] The present invention relates to a device worn on a user's finger to detect and collect the user's biosignals.

[0002] Devices that detect biosignals such as blood pressure, heart rate, pulse, blood flow, vascular status, body temperature, body composition, eye condition, calories burned, oxygen saturation, respiration, blood sugar, BIA (Bioelectrical Impedance Analysis), GSR (Galvanic Skin Response), EDA (Electro-Dermal Activity), electromyography, electroencephalography, and electrocardiography are important tools used in clinical diagnosis and can be used to diagnose symptoms. In particular, people suffering from a disease or suspected of having a disease need to detect sudden abnormal symptoms or be warned early.

[0003] Conventional bio-signal detection devices are either too large to be noticeable or uncomfortable to wear, so they are mainly used when undergoing tests to detect bio-signals at hospitals or examination centers, and continuous monitoring is difficult.

[0004] Meanwhile, to solve these problems, wearable devices, which are devices that can be worn freely on the body like clothes, watches, or glasses, are being proposed, and following the smartwatch worn on the wrist, development of wearable devices in the form of rings worn on the finger is actively underway.

[0005] The main challenge in implementing a ring-shaped wearable device is to design a structure that fits the small size and circular, curved shape of existing wearable devices.

[0006] Additionally, as with other wearable devices, they are exposed to environments where movement occurs continuously depending on the wearer's activities, so the structure needs to be optimized to prevent the embedded electronic components from being damaged by impact.

[0007] The present invention is intended to solve the above-described problem, and to provide a ring-type biosignal collection device in which the shape of the built-in substrate is optimized in the structural design of the ring-type biosignal collection device so that the electronic elements attached to the substrate are stably in contact with the circular frame of the device and are protected from impact caused by the wearer's activities.

[0008] In order to solve the above-described problem, the ring-type bio-signal collection device of the present invention comprises an inner ring that comes into contact with a user's finger when worn on the user's finger, an outer ring that is spaced apart from the inner ring and is arranged on the outside of the inner ring, and a substrate portion that is arranged between the inner ring and the outer ring and to which an electronic element is attached, wherein the substrate portion may include at least one element attachment portion to which the electronic element is attached and a bent portion that is alternately arranged with the element attachment portion in the longitudinal direction of the substrate portion and is bent at a predetermined angle.

[0009] In one embodiment of the present invention, the substrate portion may be a flexible substrate.

[0010] In one embodiment of the present invention, the element attachment portion may be positioned so that the portion to which the electronic element is attached is parallel to the contact surface of the inner ring facing the electronic element.

[0011] In one embodiment of the present invention, the bending portion may be made of a different material from the element attachment portion.

[0012] In one embodiment of the present invention, the bending portion may include a recessed portion having a narrower width than the element attachment portion.

[0013] In one embodiment of the present invention, the bending portion may further include a cured film portion positioned on the surface of the bending portion to maintain the bending state of the bending portion.

[0014] In one embodiment of the present invention, the bent portion may include a first bent portion that is bent to protrude in a direction away from the inner ring, and a second bent portion that is bent to be positioned closer to the inner ring than the first bent portion.

[0015] In one embodiment of the present invention, the second bent portion is bent so as to protrude in a direction approaching the inner ring, and the shortest distance between the second bent portion and the inner ring may be shorter than the shortest distance between the electronic element attached to the element attachment portion closest to the second bent portion and the inner ring.

[0016] In one embodiment of the present invention, at least one of the first bending portion and the second bending portion may be made of a material different from that of the element attachment portion.

[0017] The present invention has the advantage that, according to the above-described configuration and coupling relationship, a substrate positioned inside a ring-shaped biosignal collection device is folded and built into a shape close to a circle (ring-shaped), and thus, electronic elements attached to the substrate can be in close contact with the circular frame of the ring-shaped biosignal collection device, and even if an impact occurs to the ring-shaped biosignal collection device due to the activities of a user wearing the device, the impact on the internal electronic elements is dispersed and mitigated, ultimately improving the durability of the ring-shaped biosignal collection device.

[0034] Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the drawings.

[0035] FIG. 1 is a drawing showing the internal configuration of a ring-shaped biosignal collection device according to one embodiment of the present invention.

[0036] First, the present invention relates to a ring-shaped biosignal collection device. In one embodiment, a bent portion is formed in a substrate (300) built inside to alleviate shock that may occur between an electronic element (P) attached to the substrate (300) and an inner ring (100), ultimately improving the durability of the ring-shaped biosignal collection device.

[0037] Referring to FIG. 1, a ring-shaped biosignal collection device, which is an embodiment of the present invention, may include an inner ring (100), an outer ring (200), and a substrate (300).

[0038] The outer ring (200) forms the outermost portion of the ring-shaped biosignal collection device. The material, diameter, overall shape, and function of the outer ring (200) may be applied to various embodiments of the outer ring used in existing ring-shaped biosignal collection devices.

[0039] The inner ring (100) is inserted and joined to the inside of the outer ring (200) so that the user's finger can be inserted into the inside and make contact.

[0040] Between the outer side of the inner ring (100) and the inner side of the outer ring (200), the ring-shaped bio-signal collection device of the present invention may include components for measuring the user's bio-signal and displaying the measurement results, including a substrate part (300), a battery part, etc.

[0041] A portion of the inner surface of the outer ring (200) and the outer surface of the inner ring (100) may be made of a conductive material and function as an electrode. For example, the inner surface of the outer ring (200) and the outer surface of the inner ring (100) may each include stainless steel, conductive nanoparticles, gold, and / or silver. The inner surface of the outer ring (200) and the outer surface of the inner ring (100) may be referred to as a first electrode and a second electrode, or an outer electrode and an inner electrode, respectively.

[0042] The substrate portion (300) is located between the outer side of the inner ring (100) and the inner side of the outer ring (200), and corresponds to a substrate to which various types of electronic elements (P) can be attached so that the ring-shaped biosignal collection device of the present invention can perform various functions, such as measuring a user's biosignal.

[0043] The substrate (300) may be formed as a flexible printed circuit board (FPCB). It is intended to be inserted between the circular inner ring (100) and the outer ring (200). However, the present invention is not limited thereto.

[0044] The substrate portion (300) may include an element attachment portion (310) and a bending portion (320).

[0045] The element attachment portion (310) is a portion where an electronic element (P) is attached to the substrate portion (300). Specifically, it is a portion that is alternately arranged with the bend portion (320) described below in the longitudinal direction of the substrate portion (300) (for example, it may be the L1 direction of FIG. 2) on the substrate portion (300), and can be understood as a portion where multiple electronic elements (P) are gathered and attached.

[0046] In the element attachment portion (310), the portion where the electronic element (P) is attached can be positioned parallel to the contact surface of the inner ring (100) facing the attached electronic element (P).

[0047] Specifically, even if the substrate portion (300) is formed as a flexible substrate, it cannot exhibit a sufficient circular shape due to limitations in the substrate material. The substrate portion (300) has an arc shape or the like with a different curvature from the inner ring (100), and the electronic element (P) attached to the substrate portion (300) has limitations in being positioned parallel to the inner ring (100).

[0048] When an impact occurs on the ring-type biosignal collecting device, a secondary collision occurs between several electronic elements (P) and the inner ring (100) within the device. At this time, the collision occurs unevenly on the electronic elements (P) that are not arranged parallel to the inner ring (100), and the impact is not distributed. This locally applies a strong impact to a specific part of the electronic elements (P), significantly damaging the durability of the ring-type biosignal collecting device.

[0049] Therefore, a ring-shaped bio-signal collecting device according to one embodiment of the present invention is characterized in that the structure is optimized by firstly including a bending portion (320) to be described later in the substrate portion (300) to bend the substrate portion (300) into a shape close to a circle, and secondly, by allowing the element attachment portion (310) positioned between the bending portions (320) to be positioned parallel to the contact surface of the inner ring (100) that faces the bending portions (320), and secondly, by gathering and attaching electronic elements (P) to the element attachment portion (310) positioned parallel to the contact surface of the inner ring (100), and allowing the attached electronic elements (P) to be positioned parallel to the contact surface of the inner ring (100).

[0050] Accordingly, the shock generated in the ring-shaped biosignal collection device is distributed and transmitted to several electronic elements (P) attached to the substrate (300), ultimately improving the durability of the ring-shaped biosignal collection device.

[0051] The bending portion (320) is a portion of the substrate portion (300) bent at a predetermined angle. The bending portion (320) bends the substrate portion (300) so that the substrate portion (300) is concentric with the inner ring (100) and has a circular curvature, and can be bent so that the inner angle formed by the bending faces the inner ring (100). The predetermined angle at which the substrate portion (300) is bent can be determined or modified depending on the number of the element attachment portions (310) and the bending portions (320), the curvature of the substrate portion (300) to be formed, and the angle at which the electronic element (P) attached to the element attachment portion (310) contacts the inner ring (100).

[0052] The bending portion (320) is arranged alternately with the element attachment portion (310) along the longitudinal direction (L1) of the substrate portion (300) on the substrate portion (300), and a plurality of bending portions (320) can be formed on the substrate portion (300) with a gap between them.

[0053] Next, a ring-shaped biosignal collection device according to another embodiment of the present invention will be described with reference to FIG. 2.

[0054] FIG. 2 is a drawing showing a bending part of a ring-shaped biosignal collection device according to another embodiment of the present invention.

[0055] In the description, the same configuration as the above-described embodiment is indicated by the same drawing reference numerals, and the configuration indicated by the same drawing reference numerals can be understood to represent a configuration having the same structure, performance, function, action, or effect as the above-described embodiment, or a configuration within a range that is obvious for a person skilled in the art to modify according to the state of use without difficulty, and any duplicate descriptions will be omitted or abbreviated.

[0056] This embodiment is an improvement in that the configuration of the bending portion (320) is modified from the above-described embodiment to facilitate bending of the substrate portion (300). Before describing the bending portion (320), this embodiment, like the above-described embodiment, includes an inner ring (100) that comes into contact with the finger when worn on the user's finger, an outer ring (200) that is spaced apart from the inner ring (100) and is arranged on the outside of the inner ring (100), and a substrate portion (300) that is arranged between the inner ring (100) and the outer ring (200) and to which an electronic element (P) is attached. The substrate portion (300) may include an element attachment portion (310) to which the electronic element (P) is attached, and a bending portion (320) that is alternately arranged with the element attachment portion (310) in the longitudinal direction (L1) of the substrate portion (300) and is bent at a predetermined angle.

[0057] Likewise, the substrate portion (300) may be formed as a flexible substrate, and the element attachment portion (310) may be positioned so that the portion where the electronic element (P) is attached to the element attachment portion (310) is parallel to the contact surface of the inner ring (100) facing the attached electronic element (P), and the bending portion (320) may be formed of a material different from that of the element attachment portion (310).

[0058] Referring to FIG. 2, looking at the modified part in this embodiment, the bent part (320) of the ring-shaped biosignal collection device according to this embodiment may include a recessed part (330) having a narrower width than the element attachment part (310).

[0059] The sunken portion (330) can be understood as a portion in which all or part of the bent portion (320) is sunken inward in the width direction (W1) of the substrate portion (300).

[0060] The shape of the recessed portion (330) may be various, including a semicircular shape, as long as it is a shape that is recessed inward in the width direction (W1) of the substrate portion (300), in addition to the triangular shape shown in FIG. 2, and is not limited thereto.

[0061] The recessed portion (330) may be formed only on one side of the folded portion (320). For example, in FIG. 2, only one of the first recessed portion (331) or the second recessed portion (332) may be provided. Preferably, the recessed portions (330) are formed on both sides of the folded portion (320), and the recessed portions (330) formed on both sides may be provided such that the most inwardly recessed points are located at the same position in the longitudinal direction (L1).

[0062] The bending portion (320) has a point with a narrower width than other portions in the longitudinal direction (L1) of the substrate portion (300) because it includes a recessed portion (330), and the narrow width imparts a physically different characteristic (e.g., ductility and rigidity, etc.) to the substrate portion (300) from other points, thereby providing a position where a bending line (e.g., a line formed by bending, such as the first bending line (B1) illustrated in FIG. 2) can be easily formed, and the formed bending line can better maintain the bending shape.

[0063] Accordingly, the substrate portion (300) of the ring-shaped biosignal collection device according to another embodiment of the present invention can more sufficiently form a circular shape, and the electronic element (P) attached to the element attachment portion (310) is positioned parallel to the inner ring (100) to better disperse the impact.

[0064] Next, a ring-shaped biosignal collection device according to another embodiment of the present invention will be described with reference to FIGS. 3 and 4.

[0065] Fig. 3 is a drawing showing a bending portion of a ring-shaped biosignal collection device according to another embodiment of the present invention. Fig. 4 is a cross-sectional view taken along the line AA' of Fig. 3.

[0066] In the description, the same configuration as the above-described embodiment is indicated by the same drawing reference numerals, and the configuration indicated by the same drawing reference numerals can be understood to represent a configuration having the same structure, performance, function, action, or effect as the above-described embodiment, or a configuration within a range that is obvious for a person skilled in the art to modify according to the state of use without difficulty, and any duplicate descriptions will be omitted or abbreviated.

[0067] This embodiment is an improvement in that the configuration of the bending portion (320) in the aforementioned embodiment is modified so that the bending state of the substrate portion (300) is firmly maintained. Before describing the bending portion (320), this embodiment, like the aforementioned embodiment, includes an inner ring (100) that comes into contact with the finger when worn on the user's finger, an outer ring (200) that is spaced apart from the inner ring (100) and is arranged on the outside of the inner ring (100), and a substrate portion (300) that is arranged between the inner ring (100) and the outer ring (200) and to which an electronic element (P) is attached. The substrate portion (300) may include an element attachment portion (310) to which the electronic element (P) is attached, and a bending portion (320) that is alternately arranged with the element attachment portion (310) in the longitudinal direction (L1) of the substrate portion (300) and is bent at a predetermined angle.

[0068] Likewise, the substrate portion (300) may be formed as a flexible substrate, and the element attachment portion (310) may be positioned so that the portion where the electronic element (P) is attached to the element attachment portion (310) is parallel to the contact surface of the inner ring (100) facing the attached electronic element (P), and the bending portion (320) may be formed of a material different from that of the element attachment portion (310).

[0069] Referring to FIGS. 3 and 4, looking at the modified portion in this embodiment, the bending portion (320) of the ring-shaped biosignal collection device according to this embodiment may further include a hardened film portion (340) positioned on the surface of the bending portion (320) to maintain the bending state of the bending portion (320).

[0070] The cured film (340) may be a film or layer that is attached to all or part of the surface of the folded portion (320) and is cured, and maintains the cured shape. As the cured film (340) is attached to the surface of the folded portion (320), the folded portion (320) can firmly and easily maintain the folded state.

[0071] The curing film portion (340) may be attached to the surface of the bending portion (320) including the second bend line (B2), and as illustrated in FIG. 3, the first curing film portion (341) and the second curing film portion (342) may be positioned spaced apart from each other on both sides. Without being limited thereto, the curing film portion (340) may be provided in an integral form extending along the width direction (W1) and including the second bend line (B2) and both sides.

[0072] The curing film portion (340) may be formed on both the outer surface (e.g., the first curing film portion (341)) and the inner surface (e.g., the third curing film portion (343)) of the bending portion (320) as illustrated in FIG. 4, but is not limited thereto and may be formed on only one of the outer surface and the inner surface.

[0073] The curing film portion (340) may be made of an acrylic-based ultraviolet curing material, but is not limited thereto.

[0074] Next, a ring-shaped biosignal collection device according to another embodiment of the present invention will be described with reference to FIGS. 5 to 7.

[0075] Fig. 5 is a perspective view showing a bending portion of a ring-shaped biosignal collection device according to another embodiment of the present invention. Fig. 6 is a perspective view showing a bending portion of a ring-shaped biosignal collection device according to another embodiment of the present invention. Fig. 7 is a cross-sectional view showing a bending portion and an element attachment portion of a ring-shaped biosignal collection device according to another embodiment of the present invention.

[0076] In the description, the same configuration as the above-described embodiment is indicated by the same drawing reference numerals, and the configuration indicated by the same drawing reference numerals can be understood to represent a configuration having the same structure, performance, function, action, or effect as the above-described embodiment, or a configuration within a range that is obvious for a person skilled in the art to modify according to the state of use without difficulty, and any duplicate descriptions will be omitted or abbreviated.

[0077] This embodiment is an improvement in that the configuration of the bending portion (320) is modified from the above-described embodiment so that a portion of the bending portion (320) can alleviate the impact between the substrate portion (300) and the inner ring (100) or the electronic element (P) and the inner ring (100). Before describing the bending portion (320), the present embodiment, like the previously described embodiment, includes an inner ring (100) that comes into contact with the finger when worn on the user's finger, an outer ring (200) that is spaced apart from the inner ring (100) and is arranged on the outside of the inner ring (100), and a substrate portion (300) that is arranged between the inner ring (100) and the outer ring (200) and to which an electronic element (P) is attached. The substrate portion (300) may include an element attachment portion (310) to which the electronic element (P) is attached, and a bending portion (320) that is alternately arranged with the element attachment portion (310) in the longitudinal direction (L1) of the substrate portion (300) and is bent at a predetermined angle.

[0078] Likewise, the substrate portion (300) may be formed as a flexible substrate, and the element attachment portion (310) may be positioned so that the portion where the electronic element (P) is attached to the element attachment portion (310) is parallel to the contact surface of the inner ring (100) facing the attached electronic element (P), and the bending portion (320) may be formed of a material different from that of the element attachment portion (310).

[0079] Referring to FIGS. 5 to 7, looking at the modified portion in this embodiment, the bent portion (320) of the ring-shaped biosignal collection device according to this embodiment can be divided into a first bent portion (321) that is bent to protrude in a direction away from the inner ring (100) and a second bent portion (322) that is bent to be positioned closer to the inner ring (100) than the first bent portion (321).

[0080] The first bend portion (321) and the second bend portion (322) may be parts of the bend portion (320) that are separated by cutting the inside of the bend portion (320) along the longitudinal direction (L1) of the substrate portion (300). For example, as illustrated in FIG. 5, the first bend portion (321) may be positioned on both sides of the second bend portion (322) with the second bend portion (322) interposed therebetween, and as illustrated in FIG. 6, the second bend portion (322) may be positioned on both sides of the first bend portion (321) with the first bend portion (321) interposed therebetween.

[0081] The first bend portion (321), like the aforementioned bend portion (320), is intended to bend the substrate portion (300) so that the substrate portion (300) forms a circle concentric with the inner ring (100). The first bend portion (321) is bent so as to protrude in a direction away from the inner ring (100), so that the inner angle formed in the first bend portion (321) can face the inner ring (100).

[0082] The second bend portion (322) is provided to alleviate the impact between the substrate portion (300) and the inner ring (100) or the electronic component (P) and the inner ring (100). The second bend portion (322) may be a portion that is bent so as to be positioned closer to the inner ring (100) than the first bend portion (321), and preferably, it may be bent so as to protrude in a direction closer to the inner ring (100) so that the inner angle formed in the second bend portion (322) faces the outer ring (200).

[0083] More preferably, the distance between the fourth bend line (B4) and the inner ring (100) or the shortest distance between the second bend (322) and the inner ring (100) may be provided so that the bend of the second bend (322) is shorter than the shortest distance between the electronic element (P) attached to the element attachment portion (310) closest to the second bend (322) and the inner ring (100).

[0084] Referring to FIG. 7, when the bending portion (320) is divided into a first bending portion (321) and a second bending portion (322), and the second bending portion (322) protrudes toward the inner ring (100), the second bending portion (322) can alleviate the impact between the substrate portion (300) and the inner ring (100) or the electronic component (P) and the inner ring (100), and the durability of the ring-shaped biosignal collection device including the second bending portion (322) can be greatly improved.

[0085] Under the functions of the first bending portion (321) and the second bending portion (322) described above, at least one of the first bending portion (321) and the second bending portion (322) may be made of a material different from the component attachment portion (310). For example, the first bending portion (321) may be made of a material that can better maintain a bent state than the component attachment portion (310), and the second bending portion (322) may be made of a material having elasticity to absorb shock. However, the present invention is not limited thereto.

[0086] The foregoing description of the present invention is for illustrative purposes only, and those skilled in the art will readily appreciate that modifications to other specific forms can be made without altering the technical spirit or essential characteristics of the present invention. Therefore, the embodiments described above should be understood as illustrative in all respects and not limiting.

[0087] For example, although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and those skilled in the art will understand that various modifications and variations of the embodiments are possible from this.

[0088] Therefore, the true technical protection scope of the present invention is indicated by the technical idea of ​​the patent claims described below, and all changes or modified forms derived from the image and scope of the patent claims and their equivalent concepts should be interpreted as being included in the scope of the present invention.
