文中介绍了用橡胶材料制造的压敏型电缆传感器。这种传感器上有正负电极。当压敏传感器在外力作用下发生变形引起一对电极相互接触时,传感器便进入‘ON’状态。该传感器采用导电橡胶和绝缘橡胶两种橡胶材料。导电橡胶应具有低体积电阻率和高耐久性;绝缘橡胶则应具有良好的柔软性和耐久性。
The article describes the pressure-sensitive cable sensor made of rubber material. This sensor has positive and negative electrodes. When the pressure-sensitive sensor is deformed by an external force and a pair of electrodes are brought into contact with each other, the sensor enters the ON state. The sensor is made of conductive rubber and insulating rubber two rubber materials. Conductive rubber should have low volume resistivity and high durability; insulating rubber should have good flexibility and durability.
