The era of nano-bionic: 2D materials for wearable and implantable body sensors

Ultrafast Charge Transfer 2D MoS2/Organic Heterojunction for Sensitive Photodetector

“…The newly explored two‐dimension (2D) materials exhibit distinctive applications in advanced state‐of‐the‐art devices such as sensors, [ 1 , 2 , 3 , 4 , 5 ] optical imaging, [ 6 , 7 , 8 ] FET, [ 9 , 10 , 11 , 12 ] and photodetectors (PD) [ 13 , 14 , 15 , 16 , 17 , 18 , 19 ] due to their excellent electrical and optical properties of high carrier mobility, [ 20 , 21 ] high absorption coefficient, [ 22 ] suitable band gap, [ 23 ] and strong light–matter interactions. [ 24 ] The 2D transition‐metal dichalcogenides especially MoS 2 with n‐type conductive feature due to nonmetallic defects, typically has a layer dependent band gap ranging from 1.2 to 1.9 eV, and could transfer to direct band gap when the number of layers reduced to monolayer, [ 25 , 26 ] indicating an ideal material choice for UV–visible and near infrared (NIR) photodetection.…”

A self-adhesive, self-healing and antibacterial hydrogel based on PVA/MXene-Ag/sucrose for fast-response, high-sensitivity and ultra-durable strain sensors

“…With the rapid development of artificial intelligence (AI) and the Internet of Things (IoT), there is a strong demand for flexible electronic devices for applications in health monitoring, 1 humancomputer interactions, 2,3 flexible sensing, 4 soft robotics, 5 and electronic skins. 6 Flexible strain sensors are among the most important flexible electronic devices.…”

Recent Advances in Smart Hydrogels Prepared by Ionizing Radiation Technology for Biomedical Applications

“…Biomedical materials used for human contact need to have the following characteristics: (1) they are biocompatible and (2) they have favorable physical and chemical properties, such as mechanical properties, aging resistance, plasticity, and interfacial stability [ 6 , 7 , 8 ]. Common biomedical materials are mainly metals, ceramics, and hydrogels.…”
