“…The oxygen functional groups exposed on the PEO surface provided a positive charge, showing excellent bipolarity in the triboelectric series. The C–O–C and –OH chemical bonds of PEO exhibited electron rejection owing to the low electron affinity of the hydrogen atom, which also exhibited positive properties in the triboelectric series. , …”

The development of technologies such as artificial intelligence and the Internet of Things has increased the demand for wearable, self-powered pressure sensors. Triboelectric nanogenerator (TENG)-based self-powered pressure sensors have emerged as a solution to meet this demand. However, the measurement of static and small pressure ranges remains a challenge. In this paper, we propose a self-powered pressure-sensing device based on the combination of carbon nanotube (CNT)/porous poly(dimethylsiloxane) (PDMS) composite and poly(ethylene oxide) (PEO) film. The proposed device could continuously and reliably measure static and small-range pressure through capacitive pressure sensing while harvesting energy based on the triboelectric effect. The device exhibited a remarkable sensitivity of 1.37 kPa–1 due to the incorporation of high-k materials (i.e., CNTs, a nanosized filler) in its porous structure and dielectric layer. It also had a power density of 15 mW/m2 due to the triboelectric interaction between PDMS and PEO. Finally, the fabricated device was connected to a microcontroller unit to perform energy harvesting and pressure sensing simultaneously, demonstrating its great potential as a wearable device.

The current field of human‐machine interaction (HMI) and electronic skin (e‐skin) is confronting challenges associated with energy supply, sensitivity, and biocompatibility. Traditional HMI systems, though rich in features, are constrained in their applications in the medical and wearable technology sectors due to their rigid structure and reliance on third‐party power inputs. Triboelectric nanogenerators (TENGs) based on natural materials are emerging as a focal point of research in this domain, attributed to their self‐powering capabilities, flexibility, and biocompatibility. These natural material‐based TENGs emulate the mechanical and biological characteristics of human skin, adapt to various body shapes and movements, and offer an efficient and reliable solution for the precise detection and analysis of complex, subtle physiological signals, thereby fostering innovations in wearable devices and robotic technology. This article provides a comprehensive review of recent advancements in natural material‐based TENGs, detailing the materials employed, including proteins, chitosan, and cellulose. It encapsulates their applications in the realms of electronic skin and HMI. Finally, the challenges confronted by natural material‐based TENGs are outlined and future trajectories for development in this burgeoning field are projected.

“…Efficient filters with small pores, crucial for preventing the escape of submicrometer particles, often result in increased airflow resistance, leading to higher energy costs. − The challenge lies in achieving a balance between high filtration efficiency and small pressure drops. Moreover, in challenging environments with high temperatures, high humidities, and exposure to toxic gases, there is a growing need for self-powered healthcare devices capable of both efficient air filtration and real-time health monitoring. − …”

Advanced portable healthcare devices with high efficiencies, small pressure drops, and high-temperature resistance are urgently desired in harsh environments with high temperatures, high humidities, and high levels of atmospheric pollution. Triboelectric nanogenerators (TENGs), which serve as energy converters in a revolutionary self-powered sensor device, present a sustainable solution for meeting these requirements. In this work, we developed a porous negative triboelectric material by synthesizing ZIF-8 on the surface of a cellulose/graphene oxide aerogel, grafting it with trimethoxy(1H,1H,2H,2H-heptadecafluorodecyl)silane, and adding a negative corona treatment, and it was combined with a positive triboelectric material to create a cellulose nanofiber-based TENG self-powered filter. The devices achieved a balance between a small pressure drop (53 Pa) and high filtration efficiency (98.97%, 99.65%, and 99.93% for PM 0.3 , PM 0.5 , and PM 1 , respectively), demonstrating robust filtration properties at high temperatures and high humidities. Our work provides a new approach for developing self-powered wearable healthcare devices with excellent air filtration properties.
