Embodiment 1

[0303] (Example 1: Measurement of flexion extension of elbow)

[0304] As shown in FIG. 6( a ), the sensor element 222 was attached to the elbow of the subject's left hand via the adhesive layer 28 .

[0305] Then, with the sensor element attached, the left elbow was flexed and stretched so that the amount of bending gradually increased, and the change in capacitance at this time was measured. The results are shown in Fig. 6(b).

[0306] As shown in the graph in Fig. 6(b), it can be seen that in the bending and stretching movement of the elbow joint, the electrostatic capacitance gradually increases with the gradual increase of the bending amount.

Embodiment 2

[0307] (Example 2: Measurement of respiration)

[0308] As shown in FIG. 7( a ), the sensor element 222 was attached to the subject's left chest via the adhesive layer 28 .

[0309] Then, with the sensing element attached, perform the following three actions: (1) Stop breathing for 10 seconds, (2) Breathe naturally for 10 seconds, (3) Take a deep breath for 10 seconds, and measure the electrostatic capacitance during each action . The results are shown in Fig. 7(b).

[0310] As shown in the graph in Fig. 7(b), it can be seen that the electrostatic capacitance hardly changes in the operation of (1), and the electrostatic capacitance increases in the operations of (2) and (3), respectively corresponding to the size of breathing. Furthermore, it can be estimated that in the actions of (2) and (3), about 2.5 breaths are performed within 10 seconds.

Embodiment 3

[0311] (embodiment 3: measurement of pronunciation)

[0312] As shown in FIG. 8( a ), the sensor element 222 was attached to the subject's left cheek via the adhesive layer 28 .

[0313] Then, in the state where the sensor element was attached, the Japanese pronunciation "ぁ(a) ぃ(i) ぅ(u) ぇ(e) ぉ(o)" was uttered, and the Electrostatic capacitance. The results are shown in Fig. 8(b).

[0314] As shown in the graph in FIG. 8( b ), it can be seen that the capacitance changes according to the type of pronunciation of "ぁぃぅぇぉ".

Abstract

An object of the present invention is to provide a sensor device that can be attached to a living body and can easily and reliably track the deformation of the surface of the living body. The sensing device of the present invention includes: a sensing element including a sheet-shaped first dielectric layer comprising an elastomer composition, and a first electrode layer and a second electrode layer, the first electrode layer and the second electrode layer A conductive composition containing carbon nanotubes is formed on the front and back surfaces of the first dielectric layer so that at least a part thereof faces each other across the first dielectric layer, and the first electrode layer and the opposite part of the second electrode layer as a detection part, and reversibly deformed in such a way that the area of ​​the front and back of the first dielectric layer changes; and the measuring device measures the change of the electrostatic capacitance of the detection part Measurement: attaching the sensing device to the living body for tracking the deformation of the living body surface.

Description

technical field [0001] The invention relates to a sensing device. Background technique [0002] In the field of rehabilitation (hereinafter also referred to simply as rehabilitation), the amount of exercise, the amount of movement of joints, or the range of motion of patients with motor paralysis such as incomplete paralysis or hemiplegia is measured on a daily basis, and patients during training and at rest The measurement of the number of heartbeats per minute or the number of respirations, etc. [0003] Furthermore, in the medical field, the heart rate per minute or the respiration rate of a patient or an elderly person requiring nursing care is also routinely monitored. [0004] Conventionally, methods using a ruler, a method using a goniometer, and a method using a myoelectric sensor have been used as methods for measuring the amount of exercise of a patient, the amount of motion or the range of motion of a joint or the like. [0005] However, in these methods, even i...
