Label-sensor is an essential component of the label printer which is becoming a most significant tool for the development of Internet of Things(IoT).However,some drawbacks of the traditional infrared label-sensor make the printer fail to realize the high-speed recognition of labels as well as stable ***,we propose a selfpowered and highly sensitive tribo-label-sensor(TLS)for accurate label identification,positioning and counting by embedding triboelectric nanogenerator into the indispensable roller structure of a label *** sensing mechanism,device parameters and deep comparison with infrared sensor are systematically studied both in theory and *** the results,TLS delivers 6 times higher signal magnitude than traditional ***,TLS is immune to label jitter and temperature variation during fast printing and can also be used for transparent label directly and shows long-term *** work may provide an alternative toolkit with outstanding advantages to improve current label printer and further promote the development of IoT.
