“…The visualization and inherent strain/ pressure-insensitive nature allowed the easy decoupling and separation of temperature signal from mechanical stimuli. Finally, the encapsulation bare PDMS layer was coated on the LM for triboelectric nanogenerator device fabrication in singleelectrode mode, 51 which was capable of detecting voltage output for pressure sensing (Figure 1d). Overall, the twoterminal "three-in-one" MCES would exhibit exceptional multimodal sensing capability for temperature, strain, and pressure incentive recognition by visualizing the color change and measuring different non-interfering signals of capacitance and voltage (Figure 1e).…”

It is highly desirable to construct a single-multimodal sensor that could synchronously perceive multiple stimuli without interference. Here, we propose an adhesive multifunctional chromotropic electronic skin (MCES) that can respond to and distinguish three different stimuli of stain, temperature, and pressure within the two-terminal sensing unit. The mutually discriminating "three-in-one" device converts strain into capacitance and pressure into voltage signals for a tactile stimulus response and produces visual color changes against temperature. In this MCES system, the interdigital capacitor sensor shows high linearity (R 2 = 0.998), and temperature sensing is realized via reversible multicolor switching bioinspired by the chameleon, showing attractive potential in visualization interaction. Notably, the energy-harvesting triboelectric nanogenerator in MCES can not only detect pressure incentive but also identify objective material species. Looking forward, these findings promise for multimodal sensor technology with reduced complexity and production costs that are highly anticipated in soft robotics, prosthetics, and human−machine interaction applications.

“…Then, the movable layer is left again, and the induced charges at the electrode are decreased to balance the voltage with the ground. The process is repeated, and dynamic signals are generated [ 63 ]. The types of material used for triboelectric tactile sensors include Polytetrafluoroethylene (PTFE), PDMS, Polyvinyl chloride (PVC), etc., for electron acceptor materials, and skin, PU, Indium tin oxide (ITO), cotton, etc., for electron donor materials, and materials should be properly chosen to guarantee the correct direction of electron transfer [ 63 , 64 ].…”

Human–Machine Interface (HMI) plays a key role in the interaction between people and machines, which allows people to easily and intuitively control the machine and immersively experience the virtual world of the meta-universe by virtual reality/augmented reality (VR/AR) technology. Currently, wearable skin-integrated tactile and force sensors are widely used in immersive human–machine interactions due to their ultra-thin, ultra-soft, conformal characteristics. In this paper, the recent progress of tactile and force sensors used in HMI are reviewed, including piezoresistive, capacitive, piezoelectric, triboelectric, and other sensors. Then, this paper discusses how to improve the performance of tactile and force sensors for HMI. Next, this paper summarizes the HMI for dexterous robotic manipulation and VR/AR applications. Finally, this paper summarizes and proposes the future development trend of HMI.

“…These properties are important indications to consider as options not only for the friction layer, encapsulation layer and even electrode. As for mechanical characteristics, in addition to basic mechanical strength that meets abrasion resistance, some degree of flexibility and tensile properties 175 could allow degradable polymers to be applied to wearable TENGs for power generation or motion detection. In the case of decomposition features, it is important to be stable at ambient temperature.…”
