다국어 초록 (Multilingual Abstract)

The wearable self-powered tactile triboelectric sensor is a most promising candidate in the recent development of smart electronics which can recognize various physical stimuli without using any external power source. In this paper, triboelectric sensors are fabricated by using micron level rough structured silicone elastomer with different nonwoven fabrics (thermoplastic polyurethane (TPU) and polypropylene (PP)) and simultaneously compared with smooth silicone elastomer. The sensors fabricated by using rough silicon elastomers (56 V) with TPU (56 V) and PP (19 V) shows almost 8 and 6-times better peak to peak (Vp-p) than smooth one (7 V) and PP (3 V) sensors, respectively. Compared to PP with silicon sensor, the TPU with silicon sensor shows higher Vp-p voltages irrespective of roughness because TPU has a higher tribo-positive character than PP according to triboelectric series. These wearable triboelectric sensors have potential applications in sensing human motion monitoring.
