A high-κ dielectric ceramic, magnesium niobate, can be epitaxially grown on a mica substrate and then transferred to form the gate dielectric in molybdenum disulfide transistors, providing van der Waals interfaces and high robustness to temperature and voltage.

A semifloating molybdenum disulfide homojunction exhibits a photoelectric response with a tunable amplitude and relaxation time, which can be used for reconstructive spectroscopy with high resolution and a small device footprint.

A sensor that consists of a catechol-conjugated alginate hydrogel adhesive, a stretchable 16-channel electrode array and a viscoplastic self-healing polymeric substrate, and is coupled to a pulse-controlled transcranial focused ultrasound device, can be used for closed-loop transcranial ultrasound neurostimulation.

A wireless monitoring system that integrates an organic electrochemical transistor and a near-infrared inorganic micro-light-emitting diode on a thin parylene substrate can be used to monitor biomarkers such as glucose, lactate and pH.

A wearable microgrid powered solely by fingertip perspiration can monitor metabolic biomarkers over extended periods of time.

A tactile oral pad made from a carbon nanotube and silicone composite that can be controlled by teeth and tongue movements can be used for typing, gaming and wheelchair navigation.

The further development of transistors based on two-dimensional transition metal dichalcogenides faces various issues, starting with the high density of defects typically found in the materials.
