Advances in healthcare wearable devices
Sheikh Muhammad Asher Iqbal, Imad Mahgoub, E Du et al. · 12 Apr 2021
Abstract Wearable devices have found numerous applications in healthcare ranging from physiological diseases, such as cardiovascular diseases, hypertension and muscle disorders to neurocognitive disorders, such as Parkinson’s disease, Alzheimer’s disease and other psychological diseases. Different types of wearables are used for this purpose, for example, skin-based wearables including tattoo-based wearables, textile-based wearables, and biofluidic-based wearables.…
Defects engineering for high-performance perovskite solar cells
Feng Wang, Sai Bai, Wolfgang Tress et al. · 23 Jul 2018
Abstract Metal halide perovskites have achieved great success in photovoltaic applications during the last few years. The solar to electrical power conversion efficiency (PCE) of perovskite solar cells has been rapidly improved from 3.9% to certified 22.7% due to the extensive efforts on film deposition methods, composition and device engineering. Further investigation on eliminating the…
Advances in flexible organic field-effect transistors and their applications for flexible electronics
Kai Liu, Bang Ouyang, Xiaojun Guo et al. · 20 Jan 2022
Abstract Flexible electronics have suggested tremendous potential to shape human lives for more convenience and pleasure. Strenuous efforts have been devoted to developing flexible organic field-effect transistor (FOFET) technologies for rollable displays, bendable smart cards, flexible sensors and artificial skins. However, these applications are still in a nascent stage for lack of standard high-performance material…
Triboelectric nanogenerators as flexible power sources
Yang Wang, Ya Yang, Zhong Lin Wang · 27 Sep 2017
Abstract The triboelectric nanogenerator (TENG) as a new power-generation technology was reported by Wang and co-workers in 2012. Because of its great potential for scavenging mechanical energy from living environment and sustainably driving portable devices, many researchers have developed various methods to improve output performances of TENG. In this paper, we review the progress in…
Deep learning-enabled triboelectric smart socks for IoT-based gait analysis and VR applications
Zixuan Zhang, Tianyiyi He, Minglu Zhu et al. · 26 Oct 2020
Abstract The era of artificial intelligence and internet of things is rapidly developed by recent advances in wearable electronics. Gait reveals sensory information in daily life containing personal information, regarding identification and healthcare. Current wearable electronics of gait analysis are mainly limited by high fabrication cost, operation energy consumption, or inferior analysis methods, which barely…
