Novel pressure sensors with small dimension and super-high sensitivity by metallic glasses


Metallic glasses (MG) pressure sensors with 2 times higher-pressure-capacity and 4 times higher-sensitivity than those for conventional stainless steel were developed. The sensors are Ni-based MG for high-pressure use and Zr-based MG for high-sensitivity use. This development as well as strain gauge deposition technique optimized for MG is now planning to commercialize till 2008. The result was reported in the 10 newspapers including Nikkei, Yomiuri and Kahoku-Shimpo on May 10 and broadcast by TBC and Miyagi-TV.
