Abstract
In this paper, we report our study on using P(VDF-TrFE) to develop a piezoelectric yarn. A new type of needleless nozzle for electrospinning multiple piezoelectric fibers is developed. It is verified that the developed yarn can withstand a mechanical statin as high as 40%. After 2.5 hours alignment process, the yarn has better aligned fiber bundle and lower hysteresis. Furthermore, it could produce a more linear charge output under different strain ranges. This yarn can be applied to a flexible sensor for large strain sensing.
