Brain power

The Denver Post - - BUSINESS -

A group of sci­en­tists say they have de­vel­oped a mind-con­trolled ro­botic hand that will al­low peo­ple with cer­tain types of spinal in­juries to per­form tasks such as us­ing a fork or drink­ing from a cup. Peo­ple who par­tic­i­pated in the study wore a glove-like de­vice on a hand and a cap that mea­sures elec­tric brain ac­tiv­ity and eye move­ment. The cap sends sig­nals to a tablet com­puter that con­trols the hand de­vice. Re­sults from a small study were pub­lished in the jour­nal Sci­ence Ro­bot­ics. Other ro­botic de­vices have been tested in re­cent years, but many re­quired sur­gi­cal im­plants or wet gel that trans­mits sig­nals from the scalp to the elec­trodes.
