“…The metal–PTFE–metal structure is fabricated on an etched PET film, consisting of pressure and temperature sensing parts. The pressure sensing is achieved based on the triboelectric effect of the PTFE film. − The Cu layer deposited on the etched PET surface acts as the bottom electrode, while the Cu pad on the PTFE film is used as the top electrode. Similar to the triboelectric nanogenerator, a potential is created under pressure stimuli due to the charge transfer between PTFE film and substrate that exhibit opposite tribo-polarity .…”

Mimicking human’s tactile sensory capabilities enables the functionality of electronic skin (e-skin), which plays a crucial role in the interaction between humans and the environment, and operation life and stability are key factors for the application. Here, we present the development of passive e-skin with a layered structure to realize tactile capabilities. No external energy supply is required during the achievement of the tactile functions. The fabricated e-skin shows high sensitivity responses with pressure and temperature stimuli simultaneously. Discrimination of surface textures and mimicking humans’ thermosensation are demonstrated by the measurements of time-dependent voltage variations and theoretical fittings. The multifunctional tactile sensing e-skin with low energy consumption provides opportunities of flexible electronics in promising important applications in robotic skins, prosthetics, and wearable sensors.

Recent Progress on Triboelectric Nanogenerators for Vibration Energy Harvesting and Vibration Sensing

The triboelectric nanogenerator (TENG) is a recent technology that reforms kinetic energy generation and motion sensing. A TENG comes with variety of structures and mechanisms that make it suitable for wide range of applications and working conditions. Since mechanical vibrations are abundant source of energy in the surrounding environment, the development of a TENG for vibration energy harvesting and vibration measurements has attracted a huge attention and great research interest through the past two decades. Due to the high output voltage and high-power density of a TENG, it can be used as a sustainable power supply for small electronics, smart devices, and wireless sensors. In addition, it can work as a vibration sensor with high sensitivity. This article reviews the recent progress in the development of a TENG for vibration energy harvesting and vibration measurements. Systems of only a TENG or a hybrid TENG with other transduction technologies, such as piezoelectric and electromagnetic, can be utilized for vibrations scavenging. Vibration measurement can be done by measuring either vibration displacement or vibration acceleration. Each can provide full information about the vibration amplitude and frequency. Some TENG vibration-sensing architectures may also be used for energy harvesting due to their large output power. Numerous applications can rely on TENG vibration sensors such as machine condition monitoring, structure health monitoring, and the Internet of things (IoT).

Acceleration sensors have a wide variety of applications for industrial engineering, biology and navigation. However, passive sensing, narrow detection range, large size, and high manufacturing cost curb their further development. Here, we present a miniaturized acceleration sensor (MAS) with rationally patterned electrodes, based on the single electrode triboelectric mechanism, featuring small size, high accuracy, large detection scale, and environmental friendliness. A stainless-steel ball, as the moving part of the MAS, experiences physical movement that is converted into an electrical signal. Equipped with rationally patterned electrodes, the MAS retains the smallest size and lowest weight compared with the currently reported self-powered acceleration sensors. Benefiting from the voltage-relationship-based direction detection mechanism, eight directions can be identified by one TENG module. Consequently, rotated 22.5° relatively, two TENG modules enable the MAS to detect 16 directions. Moreover, accelerations ranging from 0.1 m/s 2 to 50 m/s 2 can be identified according to the relationship of response time and accelerations in the horizontal direction. The relationship is obtained through the measurements of the sum of output voltages (VSOC) for the four bottom electrodes with varying accelerations. In addition, no distinct decrease of VSOC is observed after continuously operating for 2000 circles, presenting excellent robustness. Hence, this cost-effective and rationally patterned MAS reveals great potential for human machine interaction, VR/AR (virtual/augmented reality), sports training, and smart city.
