A Embedded Based Human Protection against Electric Shock
Subscribe/Renew Journal
A Embedded based Electric Shock Protection by automatic disconnection of supply is proposed. The Contact currents, that occur when a person touches a conducting surface at higher potential, are used to detect if the person is receiving a shock. The shock arises, contact currents flow through various paths in the body including the skin surface, creating a potential difference on the skin surface. The protection kit, to be worn on human body just like a wristwatch, monitors this potential difference and signals another circuit through wireless communication to disconnect the power supply thus saving the person’s life. It also provides protection when the person touches both the power conductors electrical shocks both with ac and dc power supplies.
