A Self-Powered Six-Axis Tactile Sensor by Using Triboelectric Mechanism

Triboelectric active sensor array for self-powered static and dynamic pressure detection and tactile imaging.

We report an innovative, large-area, and self-powered pressure mapping approach based on the triboelectric effect, which converts the mechanical stimuli into electrical output signals. The working mechanism of the triboelectric active sensor (TEAS) was theoretically studied by both analytical method and numerical calculation to gain an intuitive understanding of the relationship between the app...

Self-powered magnetic sensor based on a triboelectric nanogenerator.

Magnetic sensors are usually based on the Hall effect or a magnetoresistive sensing mechanism. Here we demonstrate that a nanogenerator can serve as a sensor for detecting the variation of the time-dependent magnetic field. The output voltage of the sensor was found to exponentially increase with increasing magnetic field. The detection sensitivities for the change and the changing rate of magn...

Human skin based triboelectric nanogenerators for harvesting biomechanical energy and as self-powered active tactile sensor system.

We report human skin based triboelectric nanogenerators (TENG) that can either harvest biomechanical energy or be utilized as a self-powered tactile sensor system for touch pad technology. We constructed a TENG utilizing the contact/separation between an area of human skin and a polydimethylsiloxane (PDMS) film with a surface of micropyramid structures, which was attached to an ITO electrode th...

Three-axis Tactile Sensor

A self-powered triboelectric nanosensor for mercury ion detection.

Mercury is a highly toxic metal that can pose serious dangers to the environment and human health. Therefore, monitoring the mercury concentration is an extremely important issue to prevent such a toxic metal from endangering human life. Hg ions are by far the most stable inorganic form of mercury, which are non-biodegradable and bioaccumulable. Even at a very low concentrations, they can still...
