Sustainable energy harvesting technologies for maintaining the social ecosystem are predominantly addressing global challenges. Nowadays, non‐toxic and low‐cost energy‐generating nature materials are getting great attention for the development of flexible triboelectric nanogenerators (TENGs). Herein, Delonix regia flowers (DRFs) derived biowaste‐based tribopositive material are used to develop the high‐performance triboelectric nanogenerator. DRFs have the presence of carbonyl, hydroxyl, and amino acids functional groups, which plays a key role to demonstrate the electron‐donating ability of the DRFs. The proposed DRFs/PTFE device with a 20 cm2 size and 6 mm separation distance exhibits a higher performance of voltage (655 V), current (59 μA), and instantaneous power (220.2 μW cm−2) under uniform external stress at 10 Hz frequency by air cylinder motor. It has also investigated the performance of the different device sizes and the spacing effect between triboelectric layers. The DRFs/PTFE‐structured TENG exhibits excellent ability to lit up the 210 light emitting diodes and run up the low‐power electronic stopwatch. According to the presented results, DRFs could be a superior candidate for triboelectric nanogenerator applications.

Triboelectric nanogenerators (TENGs) stand out as an attractive form of technology for the efficient harvest of mechanical energy and the powering of wearable devices due to their light weight, simplicity, high power density, and efficient vibration energy scavenging capabilities. However, the requirement for micro/nanostructures and/or complex and expensive instruments hinders their cheap mass production, thus limiting their practical applications. By using a simple, cost-effective, fast spray-coating process, we develop high-performance UV-curable triboelectric coatings for large-scale energy harvesting. The effect of different formulations and coating compositions on the triboelectric output is investigated to design triboelectric coatings with high output performance. The TENG based on a hybrid coating exhibits high output performance of 54.5 μA current, 1228.9 V voltage, 163.6 nC transferred charge and 3.51 mW output power. Moreover, the hybrid coatings show good long-term output stability. All the results indicate that the designed triboelectric coatings show great potential for large-scale energy harvesting with the advantages of cost-effectiveness, fast fabrication, easy mass production and long-term stability.

“…As a result, choosing natural triboelectric materials is a feasible idea for lowering the cost and processing difficulty of TENGs. [15][16][17][18][19][20] In addition, the theory of quantitative triboelectric series provides the theoretical basis for us to further enhance TENGs' performance by choosing appropriate triboelectric pairs that are completely opposite in their ability to obtain or lose electrons after contact electrification. [21,22] Hair is a very common biomaterial that is primarily composed of protein, particularly alpha-keratin.…”

Diverse triboelectric nanogenerators (TENGs) have been extensively applied in self‐powered wearable electronics. The TENG‐based demonstration using the human body as a triboelectric material is rare, though wearable electronics plays a more and more pivotal role in portable intelligent medicine. Human hair, as part of the human body, can be a component of a TENG‐based wearable system. Herein, a novel body‐based TENG configuration made of human hair and polydimethylsiloxane (PDMS)‐coated carbon cloth is proposed. Due to triboelectrification between the hair and the PDMS layer, the output voltage can deliver 1.713 and 0.377 V in the vertical contact‐separation mode and sliding mode, respectively. In addition, a self‐powered application based on the hair‐based TENG for actively monitoring the motion state by comparing the amplitude and frequency of the output voltages is successfully demonstrated. This study broadens the application of body‐based TENGs and provides a promising and feasible strategy for developing smart health monitoring.
