We present a new transparent high-performance triboelectric microgenerator (TEMG) based on an emerging material, silk fibroin. Silk fibroin has a strong ability to lose electrons and occupies a top-level positive position in the triboelectric series. It thus significantly contributes to the performance enhancement of TEMG. To efficiently harvest energy from airflow, a channel-shaped TEMG was developed...
This paper reports a novel active body motion sensor with PDMS-AgNWs structure, which is not only highly sensitive to detect body static gestures by strain-resistance response, but also self-powered to recognize both body and prosthesis motion based on triboelectrification and electrostatic induction synchronously for the first time. By attaching the sensor on human skin or robot surface directly,...
This work reports a novel stretchable thin-film generator based on electrification for effectively harvesting body motion energy. It has two working modes, the folding mode and the contact-separation (C-S) mode, under the same circuit connection. Electrospinning PU nanofibers are employed to integrate electrodes, making it not only flexible but also highly stretchable up to 100%. Micro-patterned PDMS...
This paper presents novel functional surface designed for collecting water vapor, which is combined of PDMS and the micro level hydrophilic metal alloy ball. To imitate biological structure, the metallic balls are designed as hydrophilic part and PDMS substrate as hydrophobic structure. The ball is used as nucleation centers to absorb water vapor in the air to form droplet. Then, with the drop gradually...
A simulation for studying the process of plasma enhanced chemical vapor deposition (PECVD) technology, which is a key process in through-silicon-via (TSV) technology, is proposed in this paper. Elementary models (including ions and neutral particles direct incidence, re-emission and so on) corresponding to the mechanism of PECVD are included, which contributes to the morphology of Si02 film deposition...
