NRC embarked on the SBIR Phase I research with the goal of demonstrating the proof-of-concept that novel and high performance positive temperature coefficient of resistance (PTCR) devices could be fabricated using NRC's fine powder processing technology. The thermistors that we re manufactured exhibited a greater than five order of magnitude increase in resistivity with a very rapid increase in a narrow temperature range around the switching temperature. Based on these favorable results, NRC has decided to pursue a Phase II effort. Development and commercialization will proceed in conjunction with a Fortune 500 commercial partner and will specifically target the overcurrent protection market for automotive, power distribution. and aerospace applications. If successful, these unique thermistor devices can supplant the commo nly used polymer composite overcurrent protection devices. Other large scale applications include telecommunication devices, computers, and other portable components that are powered by rechargeable batteries.
