| 제목 | Semi-permanently durablein Nanocrack based Sensor via On-Demand Healing |
| 초록 | The characteristics of mechanosensors are one of the crucial issues to detect delicate bio-signals for medical applications. Recently, nanocrack based mechanosensor inspired by spider’s vibration receptor has been a breakthrough with its high sensitivity, up to 2,000 in 2 % strain [1]. However, it is hard to use it for long cycles due to degradation of sensitivity over 1,000 cycles in 2 % strain [2]. Thus, we suggest a simple yet robust strategy for remarkable persistence and durability in nanocrack based sensor with a self-healable polymer. The self-healable polymer help the crack gap make a return to have original shape and performance. Due to the healable property, the sensitivity is stable until 10,000 cycles in 2 % strain, and with additional healing at 50 ℃, therefore, the sensor over 1,000,000 cycles can be used. Also, we elucidate locally accelerated healing by using IR LED to avoid subjecting other components in multi-circuit system. [1] Kang, Daeshik, et al., Nature 516.7530 (2014): 222-226.
