India’s ENRICH Prosthetic Hand Targets Affordable EMG-Controlled Mobility
ENRICH is a new artificial hand designed for people who have lost an upper limb.
It was developed in India at IIT Delhi’s IHFC.
The hand listens to electrical signals from a person’s muscles using one EMG channel.
These signals help the user control different grasping movements.
It can begin a grasp in about 251 milliseconds.
The hand weighs 450 grams and has 14 movable functions.
Its battery can run for up to eight hours and takes about three hours to charge.
The adjustable socket is intended to improve comfort and fit.
If it is commercialized, it may cost much less than many prosthetic hands currently available in India.
ENRICH is an indigenous multi-articulate prosthetic hand developed at IIT Delhi’s IHFC.
Its single-channel real-time EMG system enables grasping in 250.80 ± 1.1 milliseconds.
The 450-gram hand has 14 degrees of freedom and is designed for ergonomic daily use.
A 7.4 V, 1000 mAh lithium-polymer battery provides up to eight hours of operation.
Once commercialized, ENRICH is expected to cost between Rs 25,000 and Rs 50,000.
