摘要：High-performance flexible pressure sensors are highly demanded in wearable electronics for various applications. Herein, a flexible pressure sensor was designed using carbon nanotube (CNT)-wrapped polydimethylsiloxane (PDMS) microspheres (MSs). Compared to the device with flat configuration, the sensor with CNT-wrapped PDMS MSs has an enhanced sensitivity of -0.111 kPa(-1), with a lowest detectable pressure of 0.02 kPa, response time approximately 0.1 s, as well as a long-term dynamic stability more than 10,000 cycles. The sensors with CNT-wrapped PDMS MSs show the potential to be integrated into wearable electronics for real-timely monitoring the physiological signals. (C) 2018 Elsevier B.V. All rights reserved.
