    Abstract:

Applications: 1. The present invention discloses a multi fingered prosthetic hand device comprising a hand frame with one thumb and four fingers, wherein said hand frame comprises a skeleton support system with a compound finger mechanism, a muscular system having a cable or string or tendon driven mechanism, a nervous system, and an integumentary system. 2. A universal arm socket type prosthetic arm comprises a multi-fit strap-on mechanism that is adjustable according to a limb size of an amputee, wherein, said multi fingered prosthetic hand device is actuated by an input source for the motion of said fingers and thumb, for adaptive grasp and pinch operation.
Advantages: 1. The design and development of a fully functional and multi-fingered anthropomorphic hand having a single input source, for adaptive grasp and pinching operations. 2. A dexterous manoeuvre of the fingers and thumb with respect to the stimulus performing a faster movement of the distal phalanges as compared to the proximal phalanges. 3. Available hand mechanisms do not have a smooth interior surface to hold objects properly without using any prosthetic glove. The proposed design adapts to a mechanism having a smooth interior profile. 4. The universal socket arm is provided with two arm belts mounted onto the socket to grip the hand of the amputee. 5. The hand device is incorporated with an anatomically mocking thumb design and places four fingers onto the palm with the skin system (integumentary system). 6. The hand device is incorporated with a force sensor mounted on the distal phalange of the first finger. 7. The hand device is incorporating all in one microcontroller which allows us to control every aspect of hand programming through a single port, for example - Charging, Calibration, and Rebooting. 8. The universal socket arm is designed to accommodate different sizes of the limb, having characteristic features to allow the amputee to wear it easily. 9. The hand device is provided with a replaceable battery in the palm cover. 10. The present invention provides an integrated system consisting of a microcontroller, EMG board, motor driver IC and circuit with a force sensor. 11. The present invention uses compound mechanism during optimization to generate 3D printed finger links to form a skeletal system. 12. The universal socket arm is provided with EMG electrodes to 25 accommodate easy wearing of the prosthetic hand. 13. The hand device has a reduced cost of by incorporating Poly Vinyl Chloride (PVC) and 3D printed parts of the fingers.

THE VISION
THE MISSION
ABOUT I-STEM
It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
