Embodiment 2

[0057] The pressure distribution sensor system of Embodiment 2 relates to a bite force balance system.

[0058] Such as image 3 As shown, the structure of the pressure distribution sensor is U-shaped or V-shaped in a plan view, and pressure-sensitive conductive elements 4 are arranged at positions suitable for measuring the pressure balance when human teeth occlude. , to evaluate the pressure balance during occlusion. Here, wiring 2 (one is application-side wiring 2a, the other is reception-side wiring 2b) and terminals 3 (one is application-side terminal 3a, the other is reception-side terminal 3b) are the same as in the first embodiment.

[0059] Furthermore, the relationship between the pressure distribution sensor, the processing circuit, and the computer is the same as in the "basic aspect of the pressure distribution sensor system of the present invention".

[0060] Therefore, when the pressure distribution sensor system of the present invention is used, the circuit u...

Embodiment 3

[0064] The pressure distribution sensor system of Embodiment 3 relates to a spherical pressure measurement system.

[0065] Such as Figure 5 As shown, for the structure of the pressure distribution sensor of this embodiment 3, it involves arranging a plurality of pressure-sensitive conductive elements 4 on the position suitable for measuring the pressure distribution of the palm when the hand of a human or an intelligent robot grasps an object and The measurement evaluation of the pressure distribution when grasping an object is performed. In this example, if Figure 5 As shown, in the pressure distribution sensor, there are 8 pressure-sensitive conductive elements 4, which are located at 5 o'clock on the five fingertips and 3 o'clock on the root of the finger (middle finger, ring finger, little finger). In addition, the position of the pressure-sensitive conductive element 4 can be changed appropriately.

[0066] In this system, the pressure distribution sensor S is direc...

Embodiment 4

[0075] The pressure distribution sensor system of Embodiment 4 relates to a force balance measurement system for walking function measurement.

[0076] The structure of the pressure distribution sensor S of this embodiment 4 is as follows Figure 7 As shown, it can be seen that for the contact surface pressure distribution of the sole of the foot when a healthy person walks, the trajectory of the center of gravity of the load calculated based on the foot pressure distribution slowly moves from the heel to the toe side, and finally passes through the position of the big toe (see Figure 9). Moreover, what is shown in FIG. 8 is a figure which shows the contact surface diagram of the sole of a foot when a person walks.

[0077] If Parkinson's disease, cranial nerve disease, knee joint disease, and aging cause impairment of walking function, the trajectory of the center of gravity calculated based on the pressure distribution on the sole of the foot will deviate greatly. In additi...
