歪センサおよびその製造方法
Document Type and Number:
Japanese Patent JP3966278
Kind Code:
B2
Abstract:
A strain sensor includes a metal plate, a first glass layer on the metal plate, a second glass layer provided on the first glass layer and having a color different from that of the first glass layer, an electrode on the second glass layer, a strain-sensitive resistor on the second glass layer, a circuit pattern on the second glass layer for connecting the electrode to the strain-sensitive resistor, and an overcoat glass layer for covering the strain-sensitive resistor and the circuit pattern. The strain sensor allows the layers to be identified while being manufactured, hence being controlled easily in its manufacturing processes.
