| Abstract: | Even a thin layer of sweat on the surface of the skin badly reduces the sensitivity of an e.m.g. channel. This has been found to be the greatest difficulty in operating any myoelectric device in hot climates. A new method for the discrimination of functions is described. This can operate an artificial hand successfully for sequential movements even if the sensitivities of the e.m.g. channels change at random within 30%. The method has been tested for five movements. |
