A Miniaturized Electrostatic Field Sensor Based on MOS Depletion-Layer Capacitance Modulation
Nature · By Xinting Liu ·
The 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.
