Chicken skin based Milli Watt range biocompatible triboelectric nanogenerator for biomechanical energy harvesting

Abstract

This work reports a high-performance, low-cost, biocompatible triboelectric nanogenerator (TENG) using chicken skin (CS). The device is suitable to power wearable devices, which is critical to adapt electronics in monitoring, predicting, and treating people. It also supports sustainability by providing a cost-effective way to reduce the poultry industry's waste. It has been shown here that CS-derived biowaste is an effective means of generating tribopositive material for TENGs. The CS contains amino acid functional groups based on (Glycine, Proline, and Hydroxyproline), which are essential to demonstrate the electron-donating ability of collagen. The skin was cut into 3 × 3 cm2 and used as the raw material for fabricating the TENG device with a stacking sequence of Al/Kapton/spacing/CS/Al. The chicken skin-based TENG (CS-TENG) is characterized at different frequencies (4–14 HZ) using a damping system. The CS-TENG produces an open-circuit voltage of 123 V, short-circuit current of 20 µA and 0.2 mW/cm2 of a power density at 20 MΩ. The biocompatible CS-TENG presents ultra-robust and stable endurance performance with more than 52,000 cycles. The CS-TENG is impressively capable of scavenging energy to light up to 55 commercial light-emitting diodes (LEDs), a calculator, and to measure the physiological motions of the human body. CS-TENG is a step toward sustainable, battery-less devices or augmented energy sources, especially when using traditional power sources, such as in wearable devices, remote locations, or mobile applications is not practical or cost-effective.

Advanced Triboelectric Applications of Biomass-Derived Materials: A Comprehensive Review

“…Building on this foundation, the surface modification of collagen further amplifies TENG functionality [94] (Figure 7a). The introduction of functional groups or additional crosslinking agents refines its electron affinity and charge acceptance capacity.…”

“…Additionally, their integration into wearable electronics allows for the conversion of human motion into electrical energy, thus providing a sustainable power source for sensors and electronic devices worn on the body [101]. Furthermore, collagen-based TENGs play an important role in environmental monitoring [94]. By utilizing biodegradable materials like collagen, these TENGs present an environmentally friendly option for powering sensors that track environmental changes, aligning with the push towards sustainable and green technology solutions.…”

Antibiotic-Powered Energy Harvesting: Introducing Benzylpenicillin as an Efficient Tribopositive Material for Triboelectric Nanogenerators

“…This results in an interfacial dipole with a magnitude of 4.7 Debye [49]. Thio (S), and amide (-NH-CO-) groups in the lactam ring are electron-rich, so they could easily donate electrons, hence making b-PEN a potential tribopositive material [52,53]. A schematic of the procedure employed to uniformly and firmly coat b-PEN on the adhesive surface of the Al film is shown in Figure 1b.…”

Eco-friendly, compact, and cost-efficient triboelectric nanogenerator for renewable energy harvesting and smart motion sensing

“…Thus, this nanogenerator requires more experimental tests to study its stability and reliability. On the other hand, Khan et al [ 31 ] developed low-cost biocompatible TENG composed of a tribopositive layer of chicken skin (CS). This nanogenerator generates an open-circuit voltage and short-circuit current of 123 V and 20 μA, as well as a power density of 2000 mWm −2 at 20 MΩ of load resistance.…”
