A research team led by Professor Yunlong Zi, Assistant Professor, Department of Mechanical and Automation Engineering, The Chinese University of Hong Kong (CUHK) has recently developed a self-powered wireless sensing e-sticker (SWISE). SWISE can convert the energy of the finger touch on the e-sticker into electromagnetic wave signals for wireless transmission without batteries or wires. Taking advantage of flexible, ultra-thin, and long effective transmission distance, SWISE can further the development of smart sensing and remote-control technologies. The findings have been published in the internationally renowned journal Science Advances, and the research team will cooperate with tech companies to bring related smart products to market.

In addition, the team has invented a novel triboelectric nanogenerator (TENG) the power output of which is far beyond that of the existing TENG. This invention may pave the way for using TENG to power home electrical appliances and offer an alternative renewable energy option.
