“…Due to the highly porous structures and super lightweight, aerogels have been developed in various applications. Mi et al reported a cellulose nanofibrils/PEI porous aerogel serving as positive material and in contact with PVDF in TENG as shown in Figure E. The output power density of the device improved 14.4 times due to the enhanced tribo‐positivity.…”

“…When used as a pressure sensor, both high S of 114.6 kPa −1 , wide linear response range and low detection limit of 1.0 Pa were obtained. Recently, the triboelectric nanogenerator based on aerogels were successfully used for self‐powered strain and pressure sensors . Through the integration of triboelectric materials into the aerogel film, the resultant aerogels showed a high sensitivity to even ultralight forces including finger tapping and water dripping, and monitor human motion, such as arm bending and footsteps.…”

Aerogels are unique solid‐state materials composed of interconnected 3D solid networks and a large number of air‐filled pores. They extend the structural characteristics as well as physicochemical properties of nanoscale building blocks to macroscale, and integrate typical characteristics of aerogels, such as high porosity, large surface area, and low density, with specific properties of the various constituents. These features endow aerogels with high sensitivity, high selectivity, and fast response and recovery for sensing materials in sensors such as gas sensors, biosensors and strain and pressure sensors, among others. Considerable research efforts in recent years have been devoted to the development of aerogel‐based sensors and encouraging accomplishments have been achieved. Herein, groundbreaking advances in the preparation, classification, and physicochemical properties of aerogels and their sensing applications are presented. Moreover, the current challenges and some perspectives for the development of high‐performance aerogel‐based sensors are summarized.

In nature, bioelectricity refers to electrical potentials and currents produced by or used within living cells, tissues, and organisms for electrolocation, predation, or protection. Electric eels can generate huge amounts of power using electric organs that are arranged in stacks of electrocytes. One critical, recent issue for electronic gadgets is that energy storage systems are incapable of offering enough energy for uninterrupted, long-running processes. This results in frequent recharging or inconvenient energy storage unit replacement. To address this challenge, inspired by bioelectricity phenomena, unique triboelectric nanogenerator (TENG) technology has been proposed to convert small quantities of mechanical energy into electricity without an external power supply. Several advances have been made regarding TENG-based self-charging energy storage devices. To fulfil the sustainable operation requirements of next-generation electronic devices, extensive work has been performed to integrate energy-generating TENGs with energy storing supercapacitor devices to form selfcharging power systems (SCPSs). This tutorial article focuses on recent advances and various SCPS structural designs. In addition, various power management circuits that can be integrated with TENG devices and supercapacitors are reviewed. Finally, challenges and perspectives for future SCPS progress are discussed.
