To research the power consumption of gas sensors, often the front-side of the sensor array has fabricated, the back-side of the sensor is etched to form an air gap between substrate and housing.

为了研制低功耗气体传感器，在传感器阵列上表面制备完成后，从下表面腐蚀传感器芯片的基底，以造成传感器芯片和封装室之间形成一个空气夹层。

The electronic nose is an array of nano-scale gas sensors--the maximized surface area of the nano-particles allows the most gas to pass over them--along with pattern recognition technology that can create a digital fingerprint (or noseprint, as the case may be) of specific smells.
