Ionic hydrogels outperform existing rigid and bulky electronics with many remarkable advantages including great flexibility, high conductivity, exceptional biocompatibility, and transparency, making them ideal materials for wearable human-machine interfaces (HMIs). However, traditional HMIs typically rely on external power sources, which impose limitations in terms of device size and weight, thereby compromising the user experience in HMIs. The advent of triboelectric nanogenerators (TENGs) employing ionic hydrogels has introduced a sustainable energy solution for self-powered HMIs. These TENGs can harvest the electrical energy resulting from the migration of ions induced by mechanical motion, thereby offering a sustainable energy solution for applications in wearable HMIs. Hence, the development of ionic hydrogels-based TENGs holds immense potential for the advancement of self-powered HMIs. This review first introduces the latest achievements in the fabrication of ionic hydrogel-based TENGs using diverse materials, including synthetic polymers, natural polymers, and low-dimensional materials. Then different working principles and modes of the ionic hydrogel-based TENGs are elucidated. Subsequently, the applications of these TENGs in self-powered HMIs are discussed, such as robot control, medical applications, electronic device control, and other applications. Finally, the current status and future prospects of ionic hydrogel-based TENGs in self-powered HMIs are summarized. We hope that this review will provide inspiration for the future development of self-powered human-machine interfaces utilizing ionic hydrogels-based TENGs.

Li et al proposed a sodium alginate-based TENG as the self-powered tactile sensor that exhibits a sensitivity of 0.237 V kPa –1 at pressures below 3 kPa . Due to its unique porous characteristics, the lotus root has also been widely used in other fields, such as supercapacitors, , impurity adsorption, , and electrical degradation systems .…”

Flexible tactile sensors play an important role in the development of wearable electronics and human−machine interaction (HMI) systems. However, poor sensing abilities, an indispensable external energy supply, and limited material selection have significantly constrained their advancement. Herein, a self-powered flexible triboelectric sensor (TES) is proposed by integrating lotus-root-derived porous carbon (PC) into polydimethylsiloxane (PDMS). Owing to the superior charge capturing capability of PC, the PDMS/PC (PPC)-based TES exhibits an open-circuit voltage (V oc ) of 22.8 V when it is periodically patted by skin at the pressure of 2 N and the frequency of 1 Hz, which is 5 times higher than that of a pristine PDMS-based TES. Furthermore, the as-prepared self-powered TES exhibits a high sensitivity of 3.24 V kPa −1 below 15 kPa for detecting human motion signals, such as finger clicks, joint bends, etc. Last but not the least, after the assembly of a PPC-based TES array and construction of an HMI system, the robotic snake can be controlled remotely by recognizing finger touching signals. This work shows broad potential applications for the self-powered TES in the fields of intelligent robotics, flexible electronics, disaster relief, and intelligence spying.

“…Most of the triboelectric materials are greatly influenced by humid conditions and contaminated environments. 11,12 The accumulation of water molecules and dust particles severely dissipates the surface-charge density or hinders charge transfer, which limit the output performance and long-term stability of TENGs. 13,14 Polymer materials have been regarded as potential candidates for TENG applications with the merits of light weight, high mechanical strength, and abundant functional groups.…”
