Kind: research · Impact: low

## In brief

- A miniaturized electrostatic field sensor based on MOS depletion-layer capacitance modulation is reported in Nature Communications.
- The sensor targets static and low-frequency electric fields, which are relevant in power systems and insulating materials.
- The source describes the device as compact and non-perturbing, addressing a gap where such sensors are hard to build.

## Why it matters

Compact, non-perturbing field sensors could allow electric field measurements in power equipment and insulating materials where bulky probes would disturb the field.
