A Numerical Study of the Heat Transfer Phenomena on ZnO Pyroelectric Film Sensor

摘要

This paper proposes a simulated model combined with the finite element method (F.E.M) to obtain the temperature profiles of the ZnO pyroelectric film sensor. A novel design of the top electrode is discussed and it can enhance the rate of temperature variation significantly. This study proves that the temperature variation transform to the corresponding electrical signal by the pyroelectric effect is a very important issue for the response of the pyroelectric film sensor. To go further, we will apply these results to detect the environmental temperature for the artificial skin of robots, and integrate with clothes to perform human health detection. In addition, the knowledge of the thermal-electric conjugated problem can be built through this study gradually.
