Title:
WEARABLE ELECTRIC SHOCK RECOGNITION DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/097770
Kind Code:
A1
Abstract:
The present invention relates to a wearable electric shock recognition device and, more specifically, to a wearable electric shock recognition device capable of determining whether an electric shock occurs, on the basis of an output of a sensor worn on a human body. An objective of the present invention is to provide a wearable electric shock recognition device capable of accurately determining whether an electric shock occurs regardless of a direction in which a wearer faces a high voltage source and a posture of the wearer. A wearable electric shock recognition device according to a preferable embodiment of the present invention comprises: a first to a fourth variable resistor (112, 122, 132, and 142) and a bridge resistor (150) which form a bridge circuit (1000); a resistor correction unit (210) for correcting the first to fourth variable resistors (112, 122, 132, and 142) on the bridge circuit (1000) so as to cause the bridge circuit (1000) to be in a balanced state; and a determination unit (230) for determining that an electric shock event has occurred if a magnitude of a current (i) flowing through a bridge line (BL) is determined to exceed a preconfigured electric shock threshold value. The present invention determines whether a human body is subjected to an electric shock, by using a bridge circuit converged with various measurement regions of the human body, so that whether an electric shock occurs can be accurately determined regardless of a direction in which a wearer faces a high voltage source and a posture of the wearer.
