Prosthetics help return some limb function to people who have lost a leg or arm.
With advances in biomedical engineering a prosthetic hand is gaining greater sensitivity. A team of researchers at the University of Southampton in the UK recently unveiled the latest version of the Southampton hand. Using a so-called "intelligent finger"circuitry in the fingertips senses slippage, temperature of an object and appropriate grip strength.
The researchers expect human testing of the hand within two years.
