Among these ambient energies, vibration, movement and sound can be captured and transformed into electrical power using piezoelectric materials.
Piezoelectric materials can be used to transform ambient vibrations into electrical energy that can be stored and used to power other devices.
Conversely, these materials deform when exposed to an electric field.

Study on the Dynamic Characteristics of Hot-film Flow Sensor Based on the Sampling Air Channel Wei Liu1, Zhao Lifeng 2 1.School of Transportation Science and Engineering, Beihang University, Beijing, China 2.School of Vehicle engineering, JiLin University, Jilin,China email: liuwei@ae.buaa.edu.cn Keywords: flow sensor; response; fluid; heat transfer Abstract: The hot-film flow sensors accurately measure the intake flow of engine.
The fact that the sensor adopts the structure of hot-film will lead to the size effect, and then the thermal conductivity rate of thin film material will decrease [5].
