By transferring laser-induced graphene to a hydrogel film at cryogenic temperatures, stretchable graphene–hydrogel interfaces can be created for application in wearable and implantable electronics.

An approach to soft electronics that is inspired by the emergence process of butterflies can be used to create devices that can recover from crumpling.

Memristors based on electric-field-induced phase transitions between a semiconducting and conductive phase of molybdenum ditelluride can be improved by using stressed metal contacts to strain the material closer to the phase switching point.

A transfer technique that embeds a van der Waals interface of interest in a high-adhesion matrix can decouple the properties of the functional interface from the forces required for its fabrication, providing single-step material-to-device integration.

Rhombohedral-stacked molybdenum disulfide with sliding ferroelectric behaviour can be used to create atomically thin ferroelectric transistors for computing-in-memory device applications.

Processes to recapture and reuse organic electronic materials—including conductors, semiconductors and dielectrics—using non-toxic solvents allow flexible, wearable electronic devices to be recycled sustainably.

A thin elastic conductive nanocomposite that is formed by cryogenically transferring laser-induced graphene to a hydrogel film can be used to create multifunctional sensors for on-skin monitoring and cardiac patches for in vivo detection.

The mechanical properties of sheet-like devices can be transformed via thermal modulation from an elastic state suitable for smoothing out wrinkles formed during crumpling to a plastic state suitable for free-standing operation.

An ultrasound patch that is based on multiple phased arrays of rare-earth-doped ceramic piezoelectric transducers on a stretchable substrate can be conformably attached to the surface of the body for a large field of view and operator-independent imaging of deep organs.
