Strain-sensitive, stretchable, and self-healable semiconducting film for multiplexed skin-like sensor array

Stanford researchers have developed strain-sensitive, stretchable, and self-healable semiconducting film. The researchers have created a multiplexed sensory transistor array using this material which can detect strain distribution by surface deformation. Strain-sensitive and stretchable semiconductors can function as both sensors and the active material of a transistor, integrating sensing functionality and readout devices for simplified fabrication processes and more robust and conformable devices.

The field of skin-inspired electronic materials is challenging because devices need to be sensitive to stimuli as well as stretchable. A major obstacle in the development of electronic skin has been its vulnerability to damage and the self-healing ability of this invention is a major step forward for this technology. Electronic skin can support the development of smart skin devices, soft robots, and biomedical devices. This strain-sensitive, stretchable, and self-healable semiconducting film has the potential to change the paraign of electronic skin and expand its applications.
