In this paper, we report a flexible comb electrode triboelectric–electret coupling nanogenerator using a separated friction microfiber object for self-powered position, motion direction and acceleration tracking sensing and its energy harvesting.

We present a hybrid electromagnetic generator (EMG) and leaf-shaped polytetrafluoroethylene (PTFE) triboelectric nanogenerator (TENG) with an arc-shaped brace structure for mechanical energy harvesting.

4H-SiC JBS diode with breakdown voltage higher than 4.5 kV, has been successfully fabricated on 4H-SiC wafers with epitaxial layer. In this paper we report the design, the fabrication, and the electrical characteristics of 4H-SiC JBS diode. Numerical simulations have been performed to select the doping level and thickness of the drift layer and the effectiveness of the edge termination technique. The epilayer properties of the N-type are 55 μm with a doping of 9×1014cm−3. The diodes were fabricated with a floating guard rings edge termination. The on-state voltage was 4V at JF=80 A/cm2
