一种基于PVDF的微型热释电发电机研究
A Micro Pyroelectric Generator Based on PVDF
摘要
Abstract
Based on the pyroelectric effect of polyvinylidene fluoride ( PVDF) film, a new micro pyroelectric generator was designed. The basic structure and working principle of the generator were introduced, corre-sponding experiments were completed and output characteristics of the generator under different temperature differences were analyzed through finite element method. The experimental results showed that the output volt-age increased with the increase of the matched resistance and the output current was vice versa. The maximum instantaneous output power under 20 ℃ and 40 ℃ temperature difference was 208 μW and 475 μW, respec-tively. The simulation results show that with the increase of the temperature difference, the changing rate of temperature with time increased. The respective open-circuit voltage under 20 ℃ and 40 ℃ temperature difference was 689 V and 1380 V. The simulation and experiment proved that the generator could be used as an effective means of energy harvesting, which would give guidance for further research in the future.关键词
