Unique Bioinspired Nanowire Structures for Dual-Modal Optoelectronic Electronic Skin.

As initial basic applications expand into more complex and diverse fields, including prosthesis, the metaverse, and information encryption, the diversification, multifunctionality, and customization of electronic skin (e-skin) have increasingly become prominent research trends. However, most e-skins focus on achieving higher performance and a broader response range, lacking functionality and mode customization options. Here, a mode designable bioinspired e-skin is reported, utilizing a mechanical strategy combined with interface assembly technology, and achieving the integration of optical and electrical sensing capabilities in single functional material.

Manipulating Hetero-Nanowire Films for Flexible and Multifunctional Thermoelectric Devices.

Flexible thermoelectric devices hold significant promise in wearable electronics owing to their capacity for green energy generation, temperature sensing, and comfortable wear. However, the simultaneous achievement of excellent multifunctional sensing and power generation poses a challenge in these devices. Here, ordered tellurium-based hetero-nanowire films are designed for flexible and multifunctional thermoelectric devices by optimizing the Seebeck coefficient and power factor.

Biomimetic Multimodal Receptors for Comprehensive Artificial Human Somatosensory System.

Electronic skin (e-skin) capable of acquiring environmental and physiological information has attracted interest for healthcare, robotics, and human-machine interaction. However, traditional 2D e-skin only allows for in-plane force sensing, which limits access to comprehensive stimulus feedback due to the lack of out-of-plane signal detection caused by its 3D structure. Here, a dimension-switchable bioinspired receptor is reported to achieve multimodal perception by exploiting film kirigami.
