Electrical performance enhancement of a triboelectric nanogenerator based on epoxy resin/BaTiOby Al nanopowder addition for low power electronic devices.

Triboelectric nanogenerators (TENGs) are crucial for applications such as smart sensors and bio-electronics. In the current work, we aimed for improved performance of TENGs with incorporation of BaTiOpowder, which is known for its strong ferroelectric properties, combining it with epoxy resin to improve the flexibility of our devices. We observed that our TENGs can operate for over 24 000 cycles with no degradation of function.

Flexible capacitive sensor based on 2D-titanium dioxide nanosheets/bacterial cellulose composite film.

In this paper, titanium dioxide nanosheets (TiO NSs) were incorporated into bacterial cellulose (BC) film for dielectric property tuning while maintaining the flexibility of the resulting composite paper. By taking advantage of the improved dielectric constant, the nanosheets/BC composites were employed as capacitive sensors. The fabricated devices showed the highest sensing performance of ∼2.

AC Conductivity and Dielectric Properties of Lepidocrocite-type Alkali Titanate Tunable by Interlayer Cation and Intralayer Metal.

The lepidocrocite-type layered alkali titanate TiO has diverse chemical compositions with variation in charge per formula unit , the interlayer cation , and the intralayer metal . Despite this multivariable nature, the composition dependence of physical properties is not well explored. We report herein the AC conductivity and the complementary dielectric properties of CsTiO, KTiO ( = Zn, Ni), and the mixed-interlayer ion CsKZnTiO.
