Problems solved by technology
Therefore, a plurality of pressure sensors are arranged, and sensor information etc. are processed simultaneously in parallel processing, but the wiring of the plurality of pressure sensors becomes troublesome for the device.
[0017] In addition, if the pressure of the human body deviates too much, the nursing chair or bed will cause discomfort to the human body. If the position of the person on the safety car seat is shifted, it will be difficult to deploy the airbag correctly at the center of the person in the event of an accident.

Embodiment Construction
[0055] Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0056] figure 1 and figure 2 An embodiment in which the present invention is applied to the soles or hands of a robot (controlled device) 1 is shown, and unitized tactile sensors 3 are attached to the joints of the soles of the feet and fingers or palms as the skeleton of the robot 1 . In this embodiment, if figure 1 As shown, two tactile sensors 3 are installed on the bottom of the robot 1, such as figure 2 As shown, 14 tactile sensors 3 are installed on the fingers, and one is respectively installed on the palm and the palm of the hand respectively. Since these tactile sensors 3 are arranged in conformity with the joints of the hands or soles, the joints can move freely, and the magnitude of the pressure, its area, and the position of the center of gravity of the pressure can be obtained in real time with an accuracy of less than a millimeter. If the tactile sen...

A tactile sensor for detecting a variation in pressing real-time. The tactile sensor is simple in structure, detects a variation in pressing by using reduced wires, has increased reliability and reduced cost, and can obtain information accurately. A sheet has, along its surface, resistors arranged in an X direction and Y direction, has a resistor in Z direction corresponding to the thickness direction of the sheet, and has a pressure sensitive resistor sheet (4) whose resistance in the Z direction varies according to pressing in the thickness direction. At least a pair of electrodes (9, 10, 11, 12) is placed in the periphery of the pressure sensitive sheet (4), and the electrodes conduct a current to at least either of the resistor in the X direction or the resistor in the Y direction.; Also, at least a pair of conductors (5, 6) for conducting a current to the resistor in the Z direction is provided on the surface of the pressure sensitive sheet (4).
Description
technical field [0001] The invention relates to a tactile sensor for detection and control of input information related to a pressure position, a tactile sensor for detecting contact coordinates, contact pressure and contact length with a simple method, and a tactile sensor application device using the tactile sensor. Background technique [0002] Most of the existing pressure position detection sensors can detect the pressure distribution, scan the sensors or scanning electrodes arranged on the X, Y matrix, detect the pressure distribution, and calculate the pressure position (for example, Patent Document 1, Patent Document 2). However, since all positions where pressure is applied are scanned in X and Y, it takes time to calculate the position of the center of gravity of the pressure, the area of the pressure, and the average pressure, which are necessary information. For example, even if a 50×50mm sensor with a resolution of 1mm scans at 100MHz, it takes 25μsec per elem...
