Wearable robotic glove for grip strength augmentation

This technology is a control system for wearable robotic gloves that assists with grip strength by placing a single EMG sensor at the musculotendinous junction of the flexor digitorum superficialis to measure the Mean Absolute Value (MAV) of EMG signals and identify the user's intent to exert force in real time.

Conventional multi-sensor EMG signal analysis requires individual user training, precise sensor placement, and is prone to frequent malfunctions caused by body movement.

This technology proposes a method of controlling the glove-type grip module by placing a single EMG sensor at the musculotendinous junction of the flexor digitorum superficialis and triggering the device when the measured MAV falls outside the user-defined activation and deactivation ranges. This allows for stable grip strength augmentation with a simple configuration that eliminates the need for individual training. It can be used to assist workers in industrial settings and support the daily activities of the elderly and patients, while the single-sensor configuration reduces production costs, accelerating the mass adoption of wearable robots.

Key Features:

• A single EMG sensor placed at the musculotendinous junction of the flexor digitorum superficialis to measure EMG signals
• A control unit that calculates the Mean Absolute Value of the measured EMG signals to identify the user's intent to exert force
• Determines whether to activate the device based on user-configurable activation and deactivation levels
• A glove-type grip module that operates to assist with grip strength based on the determination results
