 Brief description of the product/ technology:

 Prosthetic hands allow the amputees ability to carry o ut some of their day-to-day activities and help them to regain confidence in carrying out complicated tasks  after loss of human hands. Electromyography (EMG) has been extensively used in the past for achieving human-machine interface. In this project, we would like  to make use of tactile sensing and EMG to obtain fine control of the artificial hand. The tactile sensor based glove that will be developed using piezoelectric  material, will be used to provide appropriate feedback to control the artificial hand movement. Along with the muscle signals, the sensor array output will be used  to manipulate the force exerted by the arm based on the object shape or size to grab/release the object. In this project, we will explore the use of the different  material for sensing, for example, capacitive, pressure-based, etc. and for different mechanical properties, for example, waterproof, heat resistant, etc. Efficient  control algorithms for translating the sensors outputs will be explored in this project.  Neuro-inspired read-out for large size sensor array (64x64) will be developed  which will be implemented and tested on an ASIC. The project will specifically be targeted towards low cost and low power. The project may be extended to  include vision-sensors to include gain better control in grasp, slip, etc
 
 This project is targeted towards building low-cost, low-power, controllable prosthetic hand. Existing solutions include iLimb and Bebionic that  manufacture artificial hands with EMG control, both of these are extremely expensive and not suitable for the Asian market. In this project, we would like  to explore solutions that would reduce the cost of the prosthetic hand without compromising the control that patients could have. Our preliminary  analysis show that the cost of these hands is majorly due to the material used and the control algorithms. We would like to explore alternatives for  designing low-cost and intelligent prosthetic hand suitable for the Indian population.
