An electronic network of compact oscillatory circuits can be used to find the optimal ground state of Ising Hamiltonians.

An organic phototransistor with two complementary bulk heterojunctions exhibits light-intensity-dependent adaptation behaviour that mimics the behaviour of the human visual system.

The human body can be used as a medium to couple ambient energy and transmit power to wearable devices.

This Review examines wireless on-demand drug delivery systems that are triggered by electric fields, magnetic fields or electromagnetic radiation, and provides design guidelines for the development of such systems.

Electric-field-induced second harmonic generation can be used to measure the in-plane electric field in gallium nitride high-electron-mobility transistors and probe how dopants influence the electric field distribution.

The bandgaps of bilayers of two-dimensional C₃N can be modulated by controlling the stacking order of the layers or by applying an electric field.

By transferring two-dimensional semiconductors from rigid growth substrates together with nano-patterned metal contacts, flexible field-effect transistors can be fabricated with channel lengths down to 60 nm.

An Ising solver that is based on a network of electrically coupled phase-transition nano-oscillators, which provides a continuous-time dynamical system, can be used to efficiently solve a non-deterministic polynomial time (NP)-hard MaxCut problem.

Curvy and shape-adaptive imagers with high pixel fill factors and tunable focusing power can be created by transferring an array of ultrathin silicon optoelectronic pixels with a kirigami design onto curvy surfaces using conformal additive stamp printing.

An organic transistor that incorporates two bulk heterojunctions can exhibit active photoadaptation behaviour for light intensities that range over six orders of magnitude.

Electromagnetic waves, which are either artificially introduced or present in the immediate surroundings, can couple to the surface of the human body, creating a power transmission and energy harvesting method that can be used to provide sustainable power to wearable devices all around the body.
