Special Issue Information

Dear Colleagues,

Flexible electronics have been receiving increasing attention from researchers worldwide. High-performance flexible electronics are in high demand as a result of the expanding range of applications for sensors, energy harvesters, human–machine interfaces, etc. This Special Issue aims to provide a platform for publications on progress in this field. It will collate recent investigations on flexible electronic materials and applications and promote the future development of this emerging research field. The scope of this issue includes pressure sensors, temperature sensors, mechanical energy harvesters, bioelectronics, etc. We encourage researchers to submit their latest original research articles, perspectives, or reviews on themes including, but not limited to, the following:

  • Advanced materials for flexible electronics and bioelectronics;
  • Improvements in structural designs, material properties, and device integration for flexible sensors;
  • Technologies and applications of flexible energy harvesting materials;
  • Investigation of advanced flexible electronics;
  • Advanced technologies for fabricating flexible electronics and applications.

Contributions in the form of full papers, communications, and reviews are welcome.

With the advent of the intelligent era, flexible piezoelectric tactile sensors, as key components for sensing information and transmitting signals, have received worldwide attention. However, piezoelectric pressure sensors are still currently limited, which severely restricts their practical applications. Furthermore, the demonstrations conducted in labs are not accurate to real-world scenarios. Thus, there is an urgent need to further optimize the intrinsic piezoelectric performance and usage characteristics to meet application requirements. As a representative piezoelectric, polyvinylidene fluoride (PVDF) exhibits significant advantages in terms of excellent flexibility, chemical stability, high electromechanical conversion, low cost, and appropriate acoustic impedance, which allow it to serve as the core matrix in flexible pressure sensors. This paper aims to summarize very recent progress in flexible piezoelectric sensors based on PVDF, including their composition modulation, structure optimization, and applications. Based on a comprehensive summary of recent representative studies, we propose rational perspectives and strategies regarding PVDF-based piezoelectric sensors and provide some new insights for the research and industrial communities.
