Lingaliro la kupatsa mphamvu zamagetsi zotha kuvala ndi masensa olumikizidwa ndi intaneti okhala ndi mphamvu yochokera ku vibrate silatsopano ndipo likusintha mosalekeza. Lero pamsonkhano wa ISSCC2020, opanga ma French tchipisi ziwiri zodalirika zosonkhanitsira ndi kuunjikira magetsi kuchokera ku kugwedezeka kosalekeza ndi kugwedezeka.
Zolemba ziwiri zochokera ku malo ofufuzira a CEA-Leti zikuwonetsa mawonekedwe a ma microcircuits awiri ochotsa magetsi kuchokera ku vibrate. Chip chimodzi chimagwiritsa ntchito njira ya piezoelectric yopezera mphamvu, pomwe chinacho chimadalira kugwedezeka kwa maginito mu koyilo yamagetsi. Pazochitika zonsezi, kusungirako mphamvu ndi machitidwe opangira magetsi amamangidwa mu tchipisi ndipo alibe zinthu zopangira kunja, zomwe zimalola kuti yankho likhale losavuta kuphatikizidwa mumagetsi aliwonse oyenera.
Transducer ya piezoelectric imakhala ndi dera losinthira ma frequency a resonant. Njirayi idapangitsa kuti zitheke kukulitsa ma frequency oscillation omwe magetsi amapangidwa ndi 446%. Malinga ndi CEA-Leti, palibe amene adakwanitsa izi. Kuchita bwino kumafika 94%, ndipo chizindikiro chowunikira mphamvu () akhoza kukhala 30 nW.
Zowona, mabwalo owongolera a chip jenereta amayendetsedwa ndi magetsi omwe amapanga. Kugwiritsidwa ntchito kwa chip ndi 1 Β΅W, pomwe kusonkhanitsa mphamvu kuchokera kumalo ozungulira (vibrations) kumachokera ku 100 Β΅W mpaka 1 mW.
Chip chachiwiri chozikidwa pa maginito ozungulira ndi koyilo chikuwonetsa bwino kwambiri - mpaka 95,9%. Chofunikira ndichakuti zida zomwe zimagwiritsidwa ntchito popanga yankholi ndizopezeka komanso zotsika mtengo. The coefficient of mphamvu m'zigawo kuchokera kugwedezeka kosalekeza kufika 210%, ndi kugwedezeka mantha - 460%. Zingakhale zosangalatsa kuwona zonsezi mu mawonekedwe a kukhazikitsidwa kwa malonda, koma palibe chomwe chikudziwika pa izi.
