Pfungwa yekugonesa zvinopfekeka zvemagetsi uye internet-yakabatana sensors ine simba rinotorwa kubva kune vibrations haisi itsva uye inogara ichishanduka. Nhasi pamusangano weISSCC2020, vagadziri veFrance maviri anovimbisa machipisi ekuunganidza uye kuunganidza magetsi kubva kunogara uye nekuvhunduka vibrations.
Mapepa maviri kubva kuCEA-Leti research centre anoratidza chimiro chemamicrocircuits maviri ekubvisa magetsi kubva kuvibrations. Imwe chip inoshandisa piezoelectric nzira yekuburitsa simba, nepo imwe ichitsamira pane oscillation yemagineti mucoil yemagetsi. Muzviitiko zvose zviri zviviri, simba rekuchengetedza uye hurongwa hwekugadzira inovakwa mumachipisi uye haina kunze kwekugadzira zvinhu, zvichiita kuti mhinduro yacho ibatanidzwe nyore nyore mune chero magetsi akakodzera.
Iyo piezoelectric transducer yakashongedzerwa nedunhu rekuchinja kune simba resonant frequency. Iyi mhinduro yakaita kuti zvikwanise kuwedzera huwandu hwe oscillation frequencies umo magetsi anogadzirwa ne446%. Sekureva kweCEA-Leti, hapana anga akwanisa kuita izvi. Kubudirira kunosvika 94%, uye chiratidzo chekutevera cheiyo yakanyanya simba poindi () inogona kuva 30 nW.
Ehezve, maseketi ekudzora ejenareta chip anofambiswa nemagetsi avanoburitsa. Iyo yakazara kushandiswa kwechip i1 Β΅W, nepo kuunganidzwa kwesimba kubva munzvimbo yakatenderedza (vibrations) inotangira pa100 Β΅W kusvika 1 mW.
Yechipiri chip, yakavakirwa pane oscillating magineti uye coil, inoratidza yakatokura kupera-kusvika-kumagumo kushanda-kusvika 95,9%. Chinokosha ndechekuti zvinhu zvinoshandiswa kugadzira iyi mhinduro zvinowanikwa uye zvisingadhuri. Iyo simba rekudzoreredza chiyero kubva kunogara ichidedera inosvika 210%, uye kubva mukuvhunduka - 460%. Zvingave zvinonakidza kuona izvi zvese muchimiro chekushandiswa kwekutengeserana, asi hapana chinozivikanwa nezve izvi zvakadaro.
