Special Issue Information

Dear Colleagues,

This Special Issue is enthusiastic about the application of the triboelectric nanogenerators (TENGs) for energy harvesting and self-powered sensors. TENGs are innovative energy-harvesting and active sensing technologies that show a notable capability for extracting biomechanical and environmental energy. For energy harvesting, the output electrical energy of the TENG is supplied to wearable/portable electronic devices and wireless sensors in the era of the Internet of Things (IoT). Various input mechanical energy sources, including human-body-induced motion, magnetic-field-induced motion, water, sound, and wind to be harvested by the TENG. The generated output electrical signal of the TENG is a sensing signal itself when an external mechanical energy source (pressing, touching, and moving of an object) is induced. The TENG-based sensor has flexibility, stretchability, excellent material compatibility, and low cost which is a unique applicant technology for AI (Artificial Intelligence). Also, it can easily be fabricated without the use of any expensive material or complex fabrication method.

In this special issue, we invite you to submit new research works that explore state-of-the-art and recent advances of TENG-based energy harvesting and self-powered sensors including touch, pressure, physical, chemical, and audio sensors in addition to comprehensive review are welcome.

This study aimed to develop a simple but effective mechanical-to-electrical energy conversion for harvesting hydrokinetic energy based on triboelectric nanogenerator (TENG) technology. Here, a direct-current fluid-flow-based TENG is reported as a potential solution to solve the inconvenience of directly powering electronic devices where direct-current (DC) power is required. The falling of a water droplet (about 1.06 mL) from an elastomeric pipe can generate an open-circuit voltage of ~35 V, short-circuit current of 3.7 µA, and peak power of 57.6 µW by passing through a separated electrode. Notably, the electrical responses have the distinct characteristics of pulsed direct current. The ability to generate DC outputs enables the TENG to directly drive electronic devices. Our experimental results prove that this TENG can act as a power source to directly light up 50 light-emitting diodes without requiring a rectifier, and, also, the produced electric energy was demonstrated that can be stored directly in a capacitor to power commercial temperature and humidity IoT sensors. Furthermore, the device shows a greatly varied output voltage based on the droplet flow rate, with a linearity R2 = 0.998. This work highlights a promising potential for applications in harvesting hydrokinetic energy and self-powered sensors and systems. Full article
