One of the research is the piezoelectric ceramic material PZT-5A cover with stainless steel piezoelectric generator. The power generation actuator is combined with the triboelectric nano-generator of the zigzag origami structure, there are different microstructures on the static triboelectric sensor, improving its output and power supply ability, generate a stable and high output hybrid sensor for medical leg aid Measurement. Using different signals produced by wearing medical leg aids for signal analysis and motion sensing, and then using machine learning Long Short Term Memory (LSTM) algorithm to distinguish different actions for data learning as dynamic identification. The second indicator is the possibility of using PVDF piezoelectric film sensor combined with piezoelectric film to make a power generation sensor for collecting wind energy. It is manufactured using a 3D printer produce wind pipe incorporates a hybrid energy generation sensor into it to collect wind energy. It is expected to be used as a self-powered nozzle witch can save wind energy and sensing different wind signal. Collecting wind energy produces give a stable supply of electricity. The sensor has good development potential in the future.
