Mass-Producible CuBr Thick Film Gas Sensors and its Highly Selective Ammonia Sensing Properties

Prototype copper (I) bromide (CuBr) thick film ammonia sensors were fabricated by a simple painting process and those gas sensing properties at room temperature were evaluated. These sensors showed performance comparable to the highly sensitive and highly selective CuBr thin film sensors in the literatures. The sensor is expected to be the first mass-producible commercial CuBr sensor since this can be manufactured in the same way as our commercial MEMS metal oxide semiconductor sensors.
