Self-powered transparent glass-based single electrode triboelectric motion tracking sensor array

Abstract

A glass-based single electrode triboelectric generator (SETEG) is developed with polydimethylsiloxane (PDMS) as the negative material. Its performance under different contact forces, frequencies and spacers is investigated in detail. The SETEGs have higher electric output under higher contact force, frequency and spacer, and show better performance with a thinner glass layer at lower humidity condition. An open circuit voltage, short circuit current and power up to 318 V, 8.3 μA and 427 μW are obtained for a SETEG of 5×5 cm 2 size. Based on the study, a tracking sensor array consisting of nine 5×5 mm 2 SETEGs is proposed and developed. A LabVIEW-based automatic measurement system is also developed to record, process and display the real-time output voltages of the sensing array. Results show that an output voltage up to 4 V can be easily generated when a PDMS-covered stylus touches/slides the sensor array, and the output voltages from different sensors are independent from each other. This work demonstrates the great application potential of the SETEGs sensor array for self-powered detection, tracking or monitoring motion or a touch of a stylus or some objects, thus would be very useful for touch screen display, handheld tracking device, domestic security, traffic monitoring etc.

Realizing the potential of polyethylene oxide as new positive tribo-material: Over 40 W/m2 high power flat surface triboelectric nanogenerators

“…The TENGs have three basic operating modes: two electrode contact [12], single electrode contact [13] and sliding modes [14], with the first one being the preferred one owing to its simple architecture and high performance. The contact mode TENGs typically consist of two insulators with electric polarities far apart in the triboelectric series [15], i.e.…”

A Single‐Mode, Self‐Adapting, and Self‐Powered Mechanoreceptor Based on a Potentiometric–Triboelectric Hybridized Sensing Mechanism for Resolving Complex Stimuli

“…The triboelectric part employs a single‐electrode sensing configuration with a microstructured friction layer placed on the top of an electrode layer. [ 20–23 ] The potentiometric part is formed by a microstructured electrolyte, a reference electrode, and a sensing electrode. One end of the electrolyte is fully connected to the reference electrode and the microstructured side is set against the sensing electrode.…”

Recent progresses on paper‐based triboelectric nanogenerator for portable self‐powered sensing systems

“…As a substrate material，paper has the characteristics of flexibility, light weight, low cost and biocompatibility. Compared with metal, 23 glass, 26 and plastic 59 paper also has some unique advantages. The conductive materials and piezoelectric materials can be better coasted on the surface of the paper, and even can adhere to the substrate during bending, stretching and twisting.…”

“…So far, although different forms of mechanical energies such as: human movement, 13,14 wind, 15,16 and water wave 17,18 have been harvested efficiently by varied TENGs based on four different working modes, [19][20][21][22] the functional structures all include a triboelectric material layer and a conductive layer, both of which need to be attached on a substrate material serving as a support frame to form a usable device. In generally, benefitting from the diversity of material selectivity, both the metal, 23 plastic, 24 fiber, 25 and glass 26 can be used as the substrate of TENGs. According to the different substrate material property, TENG can achieve various characteristics to meet different practical demands.…”
