“…[26] Also, more studies focus on understanding the impact of the characteristics of electrical tactile parameters on achieving intuitive tactile feedback, such as perceptual intensity. [19,27] The latest research is inspired by the selective stimulation mechanisms of the neural tactile perception system, aiming to replicate tactile information such as fine roughness, macro roughness, slipperiness, force, and temperature. [28] However, limited by the materials choices, fabricating skin-integrated on-palm haptic devices free of tactile interference, and capable of motion with multiple DOFs is still a challenge.…”

Wearable haptic devices are developed as key components to enhance the highly immersive metaverse experience. However, conventional haptic devices enabling the sensation and interaction with virtual objects are often constrained by their bulky design, tethered operation, and physical interference with the skin, especially when integrated with human hands. In this study, a cross‐interface modification process that achieves the conversion of multilayered silk fibroin films from rigid to soft is reported. This modification is favorable for applications involving large angles and multiple degrees of freedom motions. By applying electrical current through silk‐based electrodes and utilizing a self‐designed circuit, virtual tactile sensations can be generated on the entire palm. The high flexibility, stretchability, tailorable modulus, and water permeability of silk substrates enable the electrotactile devices to maintain their functionalities without impeding fine movements and natural tactile sensations in the hand. This compact electrotactile system serves as a user's new interactive terminal through wireless communications. The intimate contact interfaces reduce the unstable adhesion commonly encountered in electrotactile applications, ensuring consistent sensation during hand motions. These materials design methods and integrated systems represent a significant advancement in fabricating and integrating large‐area soft electronics.

Touch is one of the primary senses, and the receptors for touch sense are spread across the whole human body. Electrotactile displays provide tactile feedback to generate different sensations (such as tickling, tingling, itching, and pressure) in human-computer interfaces or man-machine interactions. These displays encode tactile properties, such as shape and texture, facilitating immersive experiences in virtual or remote environments. Their compact form factor and low maintenance requirements render them versatile for myriad applications. This paper is a comprehensive survey of the design and implementation of electrotactile displays, elucidating their taxonomy, cross-modal integration strategies, and psychophysical underpinnings. Emphasizing the crucial role of psychophysics, it delineates how human perception informs the design and utilization of electrotactile displays. Furthermore, this paper identifies prevalent challenges in electrotactile displays and outlines future directions to advance their development and deployment.
