Universal electronic module for biometric tracking integrated into a piece of jewelry

Abstract

The present invention relates to a universal electronic biometric tracking module designed for integration into existing jewelry (bracelets, bangles, watches, etc.). The device comprises a processor, a wireless module, a rechargeable battery, a heart rate sensor, and an accelerometer, mounted on a printed circuit board (PCB) encapsulated in a curved, magnetic housing. The assembly attaches magnetically or via magnetic adhesion to the inside of the jewelry, ensuring continuous physiological measurement and wireless communication with a mobile device. The invention offers a discreet, universal, and comfortable solution for health monitoring.

Description

Title of the invention: Universal electronic module for biometric tracking integrated into a piece of jewelry

[0001] Technical field The present invention relates to the field of portable electronic physiological monitoring devices, and more particularly a compact universal biometric measurement module intended to be integrated inside an existing piece of jewelry (bracelet, watch, bangle, necklace, or any other accessory worn on the body). The invention aims to provide a health monitoring solution (heart rate, sleep, activity, etc.) without requiring the purchase of a dedicated connected device, using the jewelry already owned by the user as a support.

[0002] Prior art The physiological monitoring devices available to date are mostly connected watches or electronic bracelets incorporating internal sensors. However, these devices have several limitations: - Their visible technological aspect detracts from discretion and aesthetics, - they require a specific purchase - and they do not easily integrate with the diversity of jewelry already worn (bracelets, necklaces, bangles, etc.). Some removable solutions exist, but they remain bulky and do not allow for universal or discreet attachment to different supports. The present invention proposes an innovative approach consisting of designing a self-contained, flat and magnetic module, capable of being discreetly integrated inside any piece of jewelry, without altering its appearance or comfort.

[0003] Technical problem solved The invention aims to provide a modular, thin, and universal device intended for: - to collect and transmit the user's physiological data (heart rate, activity, sleep, etc.), - to integrate seamlessly with various existing jewelry pieces, - ensure a secure and removable attachment thanks to a magnetic system, - can be easily recharged via magnetic contact - and communicate wirelessly with an external device such as a smartphone. General presentation of the invention The device ([Fig. 1]) comprises: - a printed circuit board (PCB) (1), - a main processor (2) managing measurements and communication, - a wireless communication module (3) enabling exchange with a phone or mobile application, - a heart rate sensor (4), - an accelerometer (5) designed to measure movements and sleep phases, - a magnetic contact charging system (6), - a rechargeable battery (7), - a magnetic plate (8) cooperating with the lower curved metal shell (9) and the upper shell (10), the two forming a hermetically sealed “sandwich” assembly protecting the internal components while allowing reversible magnetic anchoring onto a compatible piece of jewelry or accessory. The entire module is flat and curved to fit the natural curve of the wrist or other wearing areas (ankle, neck, etc.). The device can be attached inside a rubber bracelet, a metal bangle, or any other piece of jewelry equipped with a magnetic surface or a magnetizable adhesive plate supplied with the module.

[0004] Embodiments [Fig. 1] ([[Fig. 1]]) — Exploded view of the module Figure [1] illustrates the internal composition of the device: 1. Printed circuit board (PCB) - electronic support. 2. Processor - central processing unit that takes measurements and controls communication. 3. Wireless module - integrated antenna ensuring Bluetooth® or other equivalent protocol connection. 4. Cardiac sensor - optical sensor positioned on the inner surface to measure blood flow. 5. Accelerometer - component detecting movement and physical activity. 6. Magnetic charging system - contact terminals allowing charging without a visible connector. 7. Rechargeable battery - power source housed between the shells. 8. Magnetic plate - internal fixing element. 9. Lower metal shell - curved external protection. 10. Upper shell - additional support ensuring the closure and stability of the module. Elements (9) and (10) form a sandwich structure enclosing the PCB (1) and the battery (7), ensuring a solid, thin and airtight assembly. [Fig.2] ([[Fig.2]]) — Integration into a rush Figure [Fig. 2] illustrates the module mounted inside a rigid bracelet (bangle). The module is held against the user's skin, with the side containing the heart rate sensor (4) and accelerometer (5) facing the wrist. The magnetic system (8-9) ensures an invisible attachment, without altering the external appearance of the jewelry. [Fig. 3] ([[Fig. 3]]) — Integration into a watch strap Figure 3 shows the module applied to the inner part of a rubber or silicone strap, under the case of a conventional watch. The module remains invisible in normal position, while allowing continuous measurement of physiological parameters thanks to its internal sensors. The lower metal shell (9) acts as a protective surface and a heat dissipation point.

[0005] Operation When positioned on the skin, the device activates the heart rate sensor (4) and the accelerometer (5). The data collected is transmitted via the wireless module (3) to the user's smartphone, where a dedicated application analyzes the signals (heart rate, sleep phases, activity, etc.). The module is recharged via magnetic contact (6) on a compatible base. The magnetic attachment of the module allows for easy removal for charging or cleaning, while ensuring a secure hold during daily use. By using a paragraph break (^). When used (visible if formatting marks are displayed), the following block will be considered a new paragraph.

[0006] Advantages of the invention - Universal compatibility with all types of jewelry. - Total discretion: module invisible to the naked eye. - Comfortable to wear thanks to its curved shape and thin profile. - Simple and quick recharging via magnetic contact. - Reliability and modularity: protected components, easily removable. - Possible future expansion to include notifications or advanced medical tracking.
