loT is the key to building a smart city, in which sensors act as eyes and ears of the system to collect and convert physical variables into electronic signals for analysis. A self-powered wireless sensing e-sticker, thin as two human hairs, developed by CUHK, converts the power of a finger touch into electromagnetic wave signals to advance the smart sensing technology. Another discovery is a TENG with high power output to better harvest mechanical and biomechanical motion.

If you have that specific ASPM genotype that enjoys the ups and downs of tone language, that’s the way you’ll go and about 70% of Cantonese speakers participating in a CUHK study had it, with better tone perception. If you don’t, or aren’t Chinese, all is not lost. Music training may help you improve your performance in lexical tones.
