STRAIN SENSOR AND PRODUCTION METHOD THEREFOR

摘要

A strain sensor comprising a metal sheet, a first glass layer on the metal sheet, a second glass sheet provided on the first glass sheet and being different in color from the first glass layer, an electrode and a strain−sensitive resistor provided on the second glass layer, a circuit pattern provided on the second glass layer, for connecting the electrode with the strain−sensitive resistor, and a overcoat glass layer for covering the strain−sensitive resistor and the circuit pattern, whereby layers formed during the production process can be easily identified to simply control the production process.
