Massachusetts Institute of Technology (MIT) ili ndi otukuka khungu lamagetsi kapena khungu la e-khungu lomwe limatha kuchotsedwa mosavuta pakhungu ngati bandeji. Khungu la e-khungu limapangidwa ndi semiconducting filimu yomwe imakhala bwino pakhungu ndipo imagwiritsidwa ntchito kuyeza kugunda kwa mtima, kuchuluka kwa shuga ndi cortisol m'magazi, komanso kuchuluka kwa mchere mu thukuta. Kulumikizana kwake ndi khungu kumachitika popanda zingwe chifukwa mulibe tchipisi, mawaya, kapena mabatire.
Ambiri mwa chatekinoloje chovala, monga tikudziwira, ili ndi mabatire, mawaya, masensa, ndi tchipisi. Mwachitsanzo, taganizirani zovala zanzeru zopangidwa ndi University of Purdue zomwe zimawunika zofunikira za thupi. Zovala zawo zanzeru zimatha kuchapidwa ndipo zimalumikizana ndi khungu popanda zingwe kudzera pa WiFi kapena mafunde a wailesi. Izi zimachitika chifukwa koyilo yoyendetsa ndi nano-circuitry imayikidwa munsalu ya nsalu.
Komabe, nkhani ya MIT's e-skin ndi yosiyana pang'ono. Chipangizocho, poyambira, sichinapangidwe e-nsalu. Ndipo ilibenso ma coil oyendetsa ophatikizidwa mu kapangidwe kake. Njira yomwe imalankhulirana ndi khungu ndi kudzera mu zipangizo zomwe zimagwiritsidwa ntchito popanga.
Zida zomwe zimagwiritsidwa ntchito popanga e-skin
Khungu lamagetsi limapangidwa kuchokera ku gallium nitride, chinthu chotambasuka chomwe chimathandizira katundu wa piezoelectric. Katundu wa piezoelectric wazinthu amatanthauzidwa ngati kutembenuka kwa makina olowera kapena kupsinjika kwamakina monga kutambasulira kukhala mphamvu yamagetsi kapena ma siginecha. Ofufuzawo adapeza kuti kutambasula zinthu za gallium nitride kumapanga zizindikiro zamagetsi.
Mu phunziro lawo lofalitsidwa mu Science, Yeongin Kim et al. adapeza kuti gallium nitride, ikaphatikizidwa ndi golidi, imapanga ma siginecha amagetsi okhala ndi kunjenjemera kopangidwa ndi kugunda kwamtima kulikonse ndi thukuta lopangidwa. Zosanjikiza zagolide zomwe zidagwiritsidwa ntchito apa zidakulitsa zolowa ndi zotuluka.
Akatswiri amapanga “khungu” lamagetsi lopanda chip, opanda zingwe: Chipangizochi chimamva ndikutumiza mauthenga okhudzana ndi kugunda kwa mtima, thukuta, ndi kuwala kwa ultraviolet, popanda tchipisi tambirimbiri kapena mabatire. https://t.co/eOqFoPP6pP pic.twitter.com/he1vII0ga4

Zigawo pa e-skin
Nembanemba ya piezoelectric gallium nitride yomwe idagwiritsidwa ntchito mu phunziroli inali yocheperapo nthawi 100 kuposa tsitsi la munthu. Izi zikutanthauza kuti nembanembayo imatha kukhudzidwa ndi mawonekedwe amtundu wapakhungu, monga lub-dub yamtima. Gallium nitride ikaphatikizidwa ndi nembanemba yopyapyala komanso yozindikira ayoni, imatha kuyeza kuchuluka kwa mchere mu thukuta.
Olembawo adanenanso kuti kusintha zigawo za gallium nitride kumasintha zomwe zimayesa. Wolemba nawo Jun Min Suh adalongosola kuti "mukasintha nembanemba yozindikira, mutha kuzindikira chilichonse chomwe mukufuna, monga glucose, kapena cortisol yokhudzana ndi kupsinjika".
Zotsatira za kafukufukuyu zikuwonetsanso kuti khungu la e-skin-based e-skin lingagwiritsidwe ntchito pakapita nthawi ndipo limakhudzidwa kwambiri ndi zovuta zamakina, kuwala kwa UV, ndi ma ion mu thukuta. Njirayi ndiyotsika mtengo ndipo imatha kulumikizidwa ndi zida zowunikira zaumoyo.
Ngongole ya zithunzi: Zithunzi zomwe zimagwiritsidwa ntchito ndi za MIT ndipo zaperekedwa kuti zigwiritsidwe ntchito ndi atolankhani.
