Triboelectric nanogenerators (TENGs) are smart alternative energy harvesters to convert mechanical energy into electrical energy to power small and portable electronic devices. A key challenge in fabricating an efficient TENG lies in the choice of an active material in addition to the mechanical stability and robust output performance of the device. This report suggests, for the first time, the use of a peritoneum membrane as a triboelectrically positive material for designing TENGs. The peritoneum covers the abdominal wall and diaphragm of mammals except for the kidneys and the adrenal glands and consists of a structure of a well-defined network of elastic fibers. Our peritoneum-based TENG (p-TENG) can generate an open-circuit output voltage of ∼550 V, output current density of ∼100 mA m–2, and instantaneous output power density of 9.4 Wm–2. This work demonstrates the p-TENG as a portable power source, a self-powered pedometer, and a speedometer, which conveys its futuristic applications for health care purposes. Our p-TENG is highly stable, delivering a constant output voltage of ∼550 V over a period of 90 days. The introduction of a biowaste peritoneum membrane as a triboelectrically positive component in the TENG has great potential as a portable alternative energy source owing to its abundance, stability, low cost, and ease of fabrication.

“…Typically, triboelectric and piezoelectric effects are two reliable approaches to convert mechanical energy to electricity for wearable electronics. Since the first report of flexible triboelectric nanogenerators (TENGs) by Fan et al, several groups have been involved in applying TENGs on skin‐inspired sensors, targeting at the realization of battery‐free monitoring and diagnostic systems . For instance, Pu et al reported a mechnosensational TENG (msTENG)‐based noninvasive micromotion sensor that is capable of translating eye blink into control command based on a multifilm structure, which could be flexibly mounted behind an eyeglass arm ( Figure a) .…”

Skin‐inspired wearable devices hold great potentials in the next generation of smart portable electronics owing to their intriguing applications in healthcare monitoring, soft robotics, artificial intelligence, and human–machine interfaces. Despite tremendous research efforts dedicated to judiciously tailoring wearable devices in terms of their thickness, portability, flexibility, bendability as well as stretchability, the emerging Internet of Things demand the skin‐interfaced flexible systems to be endowed with additional functionalities with the capability of mimicking skin‐like perception and beyond. This review covers and highlights the latest advances of burgeoning multifunctional wearable electronics, primarily including versatile multimodal sensor systems, self‐healing material‐based devices, and self‐powered flexible sensors. To render the penetration of human‐interactive devices into global markets and households, economical manufacturing techniques are crucial to achieve large‐scale flexible systems with high‐throughput capability. The booming innovations in this research field will push the scientific community forward and benefit human beings in the near future.

[128,245,[262][263][264] For example, Zhou et al [264] developed a transparent and flexible TENG device, which consists of an inkjet-printed Ag film electrode with hole patterns and a PDMS triboelectric layer. The fabricated TENG device can be used as a tapping energy harvester and a self-powered raindrop sensor for the smart window.…”

The capability of devices in future ubiquitous networked wearable and implantable electronics to efficiently scavenge and store operational power from their working environment through sustainable pathways would enable viable self‐powering schemes in societally‐pervasive applications such as advanced healthcare and robotics. Triboelectric nanogenerators (TENGs) can efficiently harvest the ubiquitous mechanical energy for powering electronics and sensors. However, the majority of demonstrated TENG prototypes have been built with materials that are not biodegradable or biocompatible, which significantly hinders the application of TENGs for wearable and implantable technologies. In this review, the recent progress of the wearable and implantable triboelectric devices built with bio‐derived natural materials is summarized. The properties of these natural biopolymers are discussed in the context of self‐powered triboelectric applications. The common manufacturing methods for processing these materials into triboelectric devices are also discussed. In addition, the applications of the bio‐derived natural materials based TENGs for in vitro and in vivo applications are discussed. Finally, the outstanding challenges and potential opportunities for the development of bio‐derived natural materials based triboelectric devices targeting wearable and implantable human‐integrated applications are analyzed.
