These devices exhibit excellent electrical properties under a large uniaxial/biaxial stretching or oft-repeated tensile force, and such stretchable devices could be well applied to mimic synapses for neuromorphic computation. Highly Stretchable MoS2-Based Transistors with Opto-Synaptic Functionalities (Adv. B Stretchable Opto-Synaptic Transistors b In article number 2200238, Na Li, Guangyu Zhang, and co-workers demonstrate highly stretchable monolayer MoS SB 2 sb field effect transistors with buckled structures.
