Abstract
Flexible pressure sensors with high sensitivity are highly desirable for monitoring human-machine interaction and human subtle physiological signal monitoring. However, it is still a great challenge to fabricate the high-performance sensor due to the limit of the high-sensitive sensing platform. Herein, a highly flexible sensitive pressure sensor was constructed based on the microporous ionogel fabricated by the in-situ polymerization method. The obtained sensors showed higher sensitivity with the maximum sensitivity of 69.61kPa−1 and faster response compared to the sensor based on the non-microstructure ionogels. Moreover, the pressure sensor showed potential application in the detection touching and non-touching activities such as finger touching, couching, eye motion and blowing. The facile fabrication and the excellent performance opened a novel way to fabricate the wearable sensor.
