Abstract
ThermoPulse is a wireless temperature sensing system that has been demonstrated to accurately and reliably read internal cure/bond temperatures of composites at depths to one-inch through common bagging materials using embedded sensors small enough to not degrade the structural performance of the composite.This project proposes meet the Air Force need for increased reading distance by modifying the ThermoPulse sensors to increase the Barkhausen response by (a) increasing the sensing wire diameter; (b)modifying antenna and driver circuitry to increase excitation field strength to effect sensor response at 6-inches away from the antenna; and (c) modifying reading antenna circuitry for greater amplification, enabling detection of the Barkhausen effect at the 6-inch distance. In order to have larger diameter wire in the sensor small enough to avoid significant flaws in the composite, the ThermoPulse sensor will need to change from a three-wire system to a two-wire system, which means modification of the temperature measurement algorithm. The system will be demonstrated in the Air Forces required 350F repair scenario with the sensor 6-inches from the antennae.
