Mechanosensation electronics (or Electronic skin, e-skin) consists of mechanically flexible and stretchable sensor networks that can detect quantify various stimuli to mimic the human somatosensory system, with sensations touch, heat/cold, pain in skin through sensory receptors neural pathways. Here we present a skin-inspired highly conformable matrix network (SCMN) successfully expands e-skin sensing functionality including but not limited temperature, in-plane strain, humidity, light,...
Great successes have been achieved in developing perovskite light-emitting devices (LEDs) with blue, green, red, and near-infrared emissions. However, as key optoelectronic devices, yellow-colored LEDs remain challenging, mainly due to the inevitable halide separation mixed perovskites under high bias, causing undesired color change of devices. In addition this color-missing problem, intrinsic toxicity poor stability conventional lead-halide also restrict their practical applications. We...
Creating a large-scale contactless user-interactive sensing display (CUISD) with optimal features is challenging but crucial for efficient human-human or human-machine interactions. This study reports CUISD based on dynamic alternating current electroluminescence (ACEL) that responds to humidity. Subsecond humidity-induced luminescence achieved by integrating highly responsive hydrogel into the ACEL layer. The patterned silver nanofiber electrode and layer, produced through electrospinning...

From effect, absolute...
Power dissipation is a fundamental issue for future chip-based electronics. As promising channel materials, two-dimensional semiconductors show excellent capabilities of scaling dimensions and reducing off-state currents. However, field-effect transistors based on materials are still confronted with the thermionic limitation subthreshold swing 60 mV decade-1 at room temperature. Here, we present an atomic threshold-switching transistor constructed by integrating metal filamentary threshold...
