Hydrogels are considered as promising materials in developing next-generation wearable sensors due to their intrinsic biocompatibility and low Young's modulus. However, there are few reports on their breathability which is very important for wear comfortability of wearable sensors. Here graphene-based hydrogel is presented with regular pores using microneedles as templates endowing them with excellent breathability (water vapor transmitting rate 2.8 kg d -1 m -2 ), which is near ten times that of human skin (water vapor transmitting rate less than 0.3 kg d -1 m -2 ). A high-performance strain sensor based on this breathable hydrogel is developed. This sensor not only possesses high sensitivity but also has an excellent linearity with strain ranging from 0% to 110%. Based on these performances, this sensor can be applied in monitoring various joint movements and muscle movements. Moreover, it can achieve barrier-free communication through Morse code.

Flexible sensor arrays are widely used for wearable physiological signal recording applications. A high density sensor array requires the signal readout to be compatible with multiple channels. This paper presents a highly-integrated remote health monitoring system integrating a flexible pressure sensor array with a multi-channel wireless readout chip. The custom-designed chip features 64 voltage readout channels, a power management unit, and a wireless transceiver. The whole chip fabricated in a 65 nm complementary metal-oxide-semiconductor (CMOS) process occupies 3.7 × 3.7 mm2, and the core blocks consume 2.3 mW from a 1 V supply in the wireless recording mode. The proposed multi-channel system is validated by measuring the ballistocardiogram (BCG) and pulse wave, which paves the way for future portable remote human physiological signals monitoring devices.

Due to the difficulties in designing sensor arrays with a wide detection range, high sensitivity, and the sensing ability to convert tangential force into normal force on the same substrate, the integration of shape and texture recognitions in one electronic skin (e‐skin) has not been realized so far. Herein, an e‐skin tactile‐sensing system is presented, based on resistive pressure‐sensing units (serving as Meissner corpuscles) unevenly distributed on a bionic hand‐shaped polyimide substrate, which can realize shape and texture recognitions concurrently. A multilayer microporous structure with different pores is designed and introduced into the sensor, which enables each sensing unit ultrahigh sensitivity and a wide detection range. Meanwhile, a customized micro‐pyramid array is developed and assembled to the sensor array, which realizes the transformation from tangential force to normal force. With the help of artificial intelligence technology, the recognition accuracy reaches 100% for 8 different shapes, and 99.7% for 10 different textures, respectively. The proposed design strategy enables compatible fabrication, simple signal processing, and convenient extension of bionic free‐shaped e‐skin, which paves a promising way for the popularization of e‐skin in large‐scale intelligent wearable fields.
