Design, Fabrication and Testing of Micro Thermal Accelerometers for Industrial Internet of Things (IoT)
Project Description

MEMS sensors are one of the 5 key technologies for Internet of Things (IoT). Although inertia-based MEMS accelerometers have been widely used in mobile computing devices, such as smartphones, tablet PC, smart watches, these accelerometers have limited shock & vibration resistance. Micro thermal accelerometer based on convection heat transfer has no moving part which can have much higher shock & vibration resistance for harsh environments in industrial IoT: smart buildings, smart factory, etc. This project is to design a micro thermal accelerometer and the mechanical packaging using commercial foundry fabrication processes to achieve excellent performance for industrial IoT.
