Hu­man-ma­chine fu­ture seen in blink of an eye

China Daily (Hong Kong) - - CHINA -

glasses’ frame, the mi­nus­cule mus­cle move­ment of a clos­ing eye mo­men­tar­ily pushes the sen­sor’s lay­ers to­gether, gen­er­at­ing an elec­tri­cal sig­nal that can be re­li­ably mea­sured,” the study said. It was pub­lished last week in the US jour­nal Sci­ence Ad­vances.

“It is su­per­sen­si­tive, sta­ble, easy and cheap,” said Pu Xian­jie, the lead au­thor of the re­port. “We are now ap­ply­ing for a patent in China and over­seas. In the near fu­ture, we ex­pect to see it on the mar­ket.”

The sen­sor can ini­ti­ate tasks such as turn­ing a light on or off. When the glasses are con­nected to a com­puter screen, the wearer can blink as a cur­sor passes over dif­fer­ent keys, typ­ing out words.

“This TENG-based mi­cro­mo­tion sen­sor is dis­tinct and unique in its fun­da­men­tal mech­a­nism, which pro­vides a novel de­sign con­cept for in­tel­li­gent sen­sor tech­niques and shows great po­ten­tial for ap­pli­ca­tion in HMIs,” Hu said.

“For our next step, we would like to ... ex­plore the great po­ten­tial of TENG sen­sors in in­tel­li­gent ro­bots.”

Crop pic­tures are clearly vis­i­ble in rice fields in Hangzhou, Zhe­jiang province, on Thursday. The im­ages were not made by aliens, how­ever. Zhang Bin, a pro­fes­sor at Zhe­jiang Univer­sity, de­vel­oped a way to make them us­ing special plant­ing tech­niques. The pic­tures look best from mid-Au­gust to Septem­ber, when the color of the leaves is bright­est, Zhang said.
