| Outline of Final Research Achievements |
A new energy harvester devise using ambient vibrations, which basically compose of nonwoven fabric structure, has been proposed for the first time to realize a minus Poisson ratio of the devise frame macroscopically by using its unique pseudo-auxetic behavior. A layer-by-layer structure of nonwoven fabrics and dense layers, where lead-free piezoelectric particles were dispersed homogeneously in both insides, led to a success that the device could stretch in-plane direction significantly as well as be flexible in a thickness mode even under high-temperature operation to obtain a maximized energy output. It was therefore concluded that an extension such as heat resistant properties was yielded newly in the future application of vibration-oriented energy harvesting.
