Skin vision can be found in many invertebrates, such as earthworms, jellyfish, and octopuses using light-sensitive rod cells in the skin. It enables optical perception and colorimetric responses, providing intriguing capabilities that human skin does not have. A bioinspired wireless, battery-free, artificial skin vision (ASV) device consisting of flexible optical and optoelectronic components which essentially mimic the hierarchical structures and biological functions of rod cells in a skin-like configuration for light sensing and signal processing is developed. The ASV device can collect sweat with integrated microfluidic channels and allow real-time measurement of on-skin fluids by monitoring the intrinsic optical properties via a customizable microprism light filter. The device also shows sensitive colorimetric responses to input stimulus at chosen detection wavelengths and demonstrates a capacity for in situ quantitative analysis of biomarkers in sweat through alternative colorimetric light filters. Multiple ASVs together create a body area network with a collection of wireless sensors that can work in parallel to acquire multidimensional human physiological signals and predict fitness variations using a specified deep learning neural network. The system has potential applications in biomimetic engineering, physiological monitoring, and intelligent personalized diagnostics.

“…It is also worthy to note that current on-skin and wearable devices mostly measure a single parameter at a particular location of the body 21 . Distributed sensor networks that can spatiotemporally map multiple physiological processes and physical movements in different regions of the body ( Supplementary Table 1) are a valuable tool for clinicians, as they can provide a rich dataset to assess a health condition, predict disease, or advance sports science and analytics 22,23 . A specific example is soft, battery-free epidermal sensors that can be adhered to various regions of the body to perform full-body skin temperature and physical pressure mapping 24 .…”

The rapid advancement of electronic devices and fabrication technologies has further promoted the field of wearables and smart textiles. However, most of the current efforts in textile electronics focus on a single modality and cover a small area. Here, we have developed a tailored, electronic textile conformable suit (E-TeCS) to perform large-scale, multimodal physiological (temperature, heart rate, and respiration) sensing in vivo. This platform can be customized for various forms, sizes and functions using standard, accessible and high-throughput textile manufacturing and garment patterning techniques. Similar to a compression shirt, the soft and stretchable nature of the tailored E-TeCS allows intimate contact between electronics and the skin with a pressure value of around~25 mmHg, allowing for physical comfort and improved precision of sensor readings on skin. The E-TeCS can detect skin temperature with an accuracy of 0.1°C and a precision of 0.01°C, as well as heart rate and respiration with a precision of 0.0012 m/ s 2 through mechano-acoustic inertial sensing. The knit textile electronics can be stretched up to 30% under 1000 cycles of stretching without significant degradation in mechanical and electrical performance. Experimental and theoretical investigations are conducted for each sensor modality along with performing the robustness of sensor-interconnects, washability, and breathability of the suit. Collective results suggest that our E-TeCS can simultaneously and wirelessly monitor 30 skin temperature nodes across the human body over an area of 1500 cm 2 , during seismocardiac events and respiration, as well as physical activity through inertial dynamics.npj Flexible Electronics (2020) 4:5 ; https://doi.

For the fabrication of deformable electronic devices, electrodes that are robust against repeated bending, twisting, stretching, folding, reversible plasticizing, and that maintain electrical conductivity, and so on, are required. Malleable and pliable silk‐derived electrodes are fabricated to enable the shape deformation of perovskite solar cells. Moisture‐driven silk‐derived electrodes show reversible plasticization with malleability and pliability, realizing diverse deformation from simple operations (including bending, folding, stretching, etc.) to complicated structures (including flower, bowknot, and paper crane). It is worth noting that the silk‐derived electrodes maintain electrical conductivity (15.8 Ω sq−1) compared to their initial value (15 Ω sq−1) even after suffering from reversible mechanical plasticization of complicated structures. Deformable perovskite solar cells are fabricated with the silk‐derived electrodes and achieve a power conversion efficiency of 10.40%. The devices maintain 92% of the initial efficiency after 1000 bends at a curvature radius of 2.5 mm. The power does not decline at 50% strain and keeps more than 60% of the initial value after stretching for 50 cycles. Malleability and pliability of silk‐derived electrodes benefit the realization of stretchable perovskite solar cells and deformable electronic devices.
