In the development of advanced batteries, it is essential to achieve both high safety
performance and energy density. One practical and effective approach is the use of solid …

Piezoelectric gels were prepared from low-volatile ionic liquid (IL) 1-ethyl-3-
methylimidazolium bis (trifluoromethylsulfonyl) imide ([Emim][TFSI]) gels, and their structural …

Flexible piezoelectric devices with poly (vinylidene fluoride–trifluoroethylene) thin films were
fabricated, and directly monitoring of the heart state and piezoelectric power generation …

We investigated the piezoelectric properties of a vibration energy harvester using large-
area, flexible cantilevers composed of polyurea thin films. The piezoelectric constant d31 of …

The surface modification of ferroelectric films is expected to improve the properties of fatigue,
which is important for application in memory devices. In this study, we fabricated thin …
