Topologically protected whirl-like magnetic textures are deterministically created and deleted using current pulses.

Enhanced wireless pressure sensors can be created by relaxing parity–time symmetry conditions.

On-chip transformers based on a rolled-up membrane platform could help deliver wireless IoT applications.

An implantable strain and pressure sensor, which is made from biodegradable polymers, could be used to track the healing of tendons and then degrade after its useful lifetime.

This Review Article assesses the different techniques used to characterize memristive switching in nanoionic devices and proposes a general framework for such devices, based on the relative strengths and weaknesses in each case.

Single isolated magnetic skyrmions can be electrically written and deleted at room temperature in a magnetic device with a technologically relevant stripline geometry, a process that can be directly observed using time-resolved X-ray pump–probe measurements.

Wireless sensors employing a generalized parity–time-symmetry telemetric sensing technique exhibit finer spectral resolution and more sensitive frequency response compared to conventional passive sensors.

On-chip radio-frequency transformers made from three-dimensional self-rolled-up coils offer both high performance and an ultra-compact device footprint.

Implantable pressure and strain sensors based on biodegradable materials have been designed to naturally decompose after their useful lifetime, eliminating the need for surgical extraction of the device.

The memristor — a resistor with memory — was first postulated back in 1971, but it took nearly four decades before it was experimentally confirmed. Leon O. Chua explains how he developed a nonlinear circuit theory in which the memristor emerges naturally as the fourth basic circuit element.
