The EPIC (Electric Potential Integrated Circuit) electric field sensor measures electric field changes without requiring physical or resistive contact. It can rapidly measure electric potential ...

This design resulted from the need for a replacement of the drop sensor in an old vending machine which is no longer in production and therefore hardly obtainable. The replacement is a homemade module ...

With the increasing adoption of hybrid high-voltage direct current (HVdc) and high-voltage alternating current (HVac) transmission systems, hybrid electric field has become an essential indicator of ...
