new sensor for measurement of fields & voltages: safe, contactless, mobile, reliable
- miniaturized sensor for measurement of static and low-frequency electric fields
- non-contact measurement of direct and alternating voltage (DC, AC)
- for high, medium and low voltage
- for mobile and stationary applications
- without grounded components – floating ground
- no on-site calibration required – can be used pre-calibrated
- robust, durable, easy to handle, safe
Level of innovation
- uniquely practical measuring principle
- first public presentation of a prototype – world premiere!
Applications
- warning of high-voltage – e.g. for workers in transformer stations as well as on power lines, for cranes, lifting platforms, airplanes, helicopters, drones etc.
- warning of electrostatic charging, prevention of dust explosions (e.g. flour, shavings)
- display of residual charge (e.g. in high-voltage lines that have been disconnected from the grid)
- monitoring of real exposure limits for electric fields (HVDC, HVAC, hybrid lines, transformer stations, etc.)
- warning of thunderstorm formation and lightning
- display of charge state for batteries and accumulators – contactless
- object identification
Target groups
- power industry
- aviation, medicine, robotics, civil engineering, mechanical engineering
- meteorology
- manufacturers of safety devices and safety equipment – e.g. ESD protective equipment
- manufacturers of measuring devices

Safe measurement of electric field strength
Novel micro-electro-mechanical sensor can reliably measure static and low-frequency fields in ranges from V/m to MV/m – for the first time also mobile and easy to handle (principle picture)
