Special Issue Information

Dear Colleagues,

Due to their favorable flexibility and adaptability, flexible and wearable electronics have exhibited enormous potential in broad applications in human–machine interaction, robotics, and healthcare monitoring. Consequently, they have become one of the most attractive and rapidly growing areas of novel interdisciplinary research. As the core components of flexible electronics, the excellent flexibility sensing performance of flexible and wearable sensors are important in guaranteeing the efficacy of flexible wearable electronics. Accordingly, this Special Issue seeks to showcase research papers, short communications, and review articles that focus on the following:

(1) Novel structural designs, material fabrication, signal processing, and modeling of flexible and wearable sensors based on all kinds of mechanisms;

(2) MEMS technique processes in wearable and flexible sensors and simulation processes in theoretical modeling;

(3) Multiple application scenarios in multivariable flexible and wearable sensor systems.

Flexible pressure sensors have shown promise applications in scenarios such as robotic tactile sensing due to their excellent sensitivity and linearity. However, the realization of flexible pressure sensors with both static and dynamic response capabilities still face significant challenges due to the properties of the sensing materials themselves. In this study, we propose a flexible pressure sensor that integrates piezoelectric and ionic capacitance mechanisms for full-domain response detection of dynamic and static forces: a “sandwich” sensing structure is constructed by printing a mixture of multi-walled carbon nanotubes (MWCNTs) onto the surface of the upper and lower electrodes, and sandwiching a polyvinylidene fluoride (PVDF) thin film between the electrodes. The device exhibits a sensitivity of 0.13 kPa−1 in the pressure range of 0–150 kPa. The sensor has a rapid dynamic response (response time 19 ms/12 ms) with a sensitivity of 0.49 mV kPa−1 based on the piezoelectric mechanism and a linearity of 0.9981 based on the ionic capacitance mechanism. The device maintains good response stability under the ball impact test, further validating its potential application in static/dynamic composite force monitoring scenarios. Full article
