Recently, human-adaptive electronic skin has attracted considerable attention because of its unique characteristics showing soft and light as a frontier ubiquitous platform. In particular, fabrication of sensitive tactile sensor devices via soft nanomaterials is desirable as an effective way to realize artificial human skin and manipulate versatile skin functions. Herein, we report on highly sensitive and flexible capacitive tactile sensors using highly conductive carbon nanotube (CNT) fiber arrays incorporated with ductile elastomer dielectric onto polydimethylsiloxane (PDMS) films by a facile but very effective method. To prove the feasibility of the proposed tactile sensors, we demonstrated the highly sensitive sensor arrays enough to detect even ultralow pressure of 0.1kPa. Moreover, we found that the sensor arrays displayed much reliable response time, which indicates a potential application to electronic skin applications. |
