Abstract:

Sensors have become a strategic requirement for various countries, and the performance of sensors determines the quality of information extraction. Due to its special surface characteristics, nanoforests have the characteristics of tip/surface effect, light transmission/absorption, molecular adsorption, etc., and have been applied in different fields such as energy, biology, medicine, photonics, etc. The traditional serial and parallel processes that can be used to prepare nanoforests have problems such as high cost, difficulty in control, susceptibility to metal pollution, and incompatibility with CMOS processes. In this report, I will introduce a new type of nanoforest structure and its preparation method. In addition, based on the wide spectrum and high absorption capacity of the nanoforests and the molecular adsorption capillary condensation effect, we have achieved the integrated application of the nanoforests in MEMS optical sensors, humidity sensors, vacuum sensors, and other devices, and greatly improved the performance of the sensors. In addition, we have also explored the intelligent application of sensors.
