Our recent research interest mainly focuses on the fabrication of piezoelectric and triboelectric power generators based on various kinds of nanomaterials. Flexible generators exhibit good performances and are easy to integrate which make it the perfect candidate for many applications, and therefore crucial to develop. In this presentation, I firstly introduce the fundamentals and possible device applications of triboelectric power generators, including their basic operation modes. Then the different improvement parameters will be discussed. As main topics, I will present a couple of recent achievements regarding highly stretchable piezoelectric-pyroelectric hybrid nanogenerators (NGs), transparent flexible graphene triboelectric NGs (TENGs), textile-based wearable TENGs, etc. The recent research and design efforts for enhancing power generation performance of generators to realize self powering of portable and wearable sensors and electronics will also be discussed in this talk. |
