Special Issue Information

Dear Colleagues,

Piezoelectric effects, an intriguing phenomenon, enable the robust and precise conversion between electrical and mechanical energies. While the fundamental mechanisms behind piezoelectricity are well established, the precise control and manipulation of the piezoelectric effect, including electrical polarization, mechanical deformation, and electromechanical coupling, continue to be an active area of scientific inquiry and technological innovation. This capability is crucial for advancing the understanding of electromechanical phenomena and unlocking a wide range of cutting-edge applications, such as energy harvesting, intelligent sensing, precision actuation, and biomedical applications.

In this Special Issue, we invite original research articles and reviews that focus on advanced piezoelectric materials, covering various aspects from fundamentals to applications. We enthusiastically welcome contributions that delve into the exploration of the piezoelectric materials and their applications, with the aim of stimulating and accelerating further breakthroughs within this captivating field.

We look forward to receiving your contributions.

Tactile sensing is currently a research hotspot in the fields of intelligent perception and robotics. The method of converting external stimuli into electrical signals for sensing is a very effective strategy. Herein, we proposed a self-powered, flexible, transparent tactile sensor integrating sliding and proximity sensing (SFTTS). The principle of electrostatic induction and contact electrification is used to achieve tactile response when external objects approach and slide. Experiments show that the material type, speed, and pressure of the perceived object can cause the changes of the electrical signal. In addition, fluorinated ethylene propylene (FEP) is used as the contact electrification layer, and indium tin oxide (ITO) is used as the electrostatic induction electrode to achieve transparency and flexibility of the entire device. By utilizing the transparency characteristics of this sensor to integrate with optical cameras, it is possible to achieve integrated perception of tactile and visual senses. This has great advantages for applications in the field of intelligent perception and is expected to be integrated with different types of optical sensors in the future to achieve multimodal intelligent perception and sensing technology, which will contribute to the intelligence and integration of robot sensing.
