Personal wearable system that detects hazardous voltages and indicates direction of the source
View Patent ↗A personal voltage detection system comprises a garment to be worn by a user and carrying a plurality of electric field sensors each facing a different direction. Each sensor comprises a transducer sensing electric field in transmitting a wireless signal representing field strength for an associated direction. An alert device is in operative communication with the plurality of sensors and comprises a control configured to monitor field strength for each sensor and determine existence of an alarm condition responsive to field strength being above a pre-select level and to generate an alarm signal indicating the associated direction of the alarm condition.
