PRESSURE SENSITIVE RESISTOR AND PRESSURE SENSITIVE SENSOR

摘要

PROBLEM TO BE SOLVED: To provide a pressure sensitive resistor and a pressure sensitive sensor capable of sensitively detecting pressure in the range between 1-20 kPa. SOLUTION: Electrodes 3 and pressure sensitive resistors 4 are each provided for opposed surfaces of a pair of base films 2. A spacer 6 is arranged between the base films 2 so as to form a prescribed gap between the pressure sensitive resistors 4. The resistance between the electrodes 3 changes due to changes in the contact state between the pressure sensitive resistors 4 according to pressure impressed via the base films 2 in the pressure sensitive sensor 1. The pressure sensitive resistors 4 are formed through the use of both conductive particles 12 coated with a polymer 11 and a binder resin having an elastic modulus in the range between 10-1,000 MPa. By this it is possible for the pressure sensitive resistors 4 and the pressure sensitive sensors 1 to sensitively detect pressure in the range between 1-20 kPa. COPYRIGHT: (C)2005,JPO&NCIPI
