A Thin Film Micro Thermocouple R.F. Energy Detector for Electro Explosive Device Wiring

A thin film thermocouple detector has been developed for use in the safety evaluation of electro explosive device wiring. The detector was fabricated using vacuum deposition techniques. Bismuth and tellurium were used as the thermoelectric materials. The resultant device has a thermoelectric power of 220 microvolts/°C and a response time of less than 17 milliseconds. Testing and calibration were accomplished using constant current pulse techniques.
