Muchinyorwa chakabudiswa munguva pfupi yapfuura mumagazini yeScientific Reports, vaongorori vanokurukura nezvekugadzirwa kwesystem inotakurika yekunzwa gasi kuti ionekwe panguva chaiyo. Sisitimu iyi itsva inobatanidza masensa epamusoro anogona kutariswa zviri nyore kuburikidza neapplication yakatsaurirwa yefoni. Tsvagiridzo iyi ine chinangwa chekupa mhinduro yakamanikana uye inoshanda yekutarisa mazinga eCO munzvimbo dzakasiyana-siyana.
Zvidzidzo zvekare zvakaratidza kukosha kwemasensa emafuta akavimbika pakuona magasi ane njodzi akadai secarbon monoxide. Kubatanidzwa kwetekinoroji dzemazuva ano, kusanganisira ma microcontrollers nema mobile apps, kunogona kuvandudza mashandiro uye kuwanikwa kwemidziyo inoona mafuta. Kushandiswa kwePN heterojunctions nezvinhu zve nanowire zvakaita seCuO/copper foam (CF) kwakawedzera kuvandudza kunzwisisika uye kusarudzwa kwemasensa aya emafuta.
Sensor iyi yakabatana nemidziyo yekuyera simba remagetsi uye resistance kuti ione shanduko ye resistance kana yasangana nehuwandu hwakasiyana hwepeturu. Mudziyo wese wakavharwa muimba yekudzora kuti uteedzere mamiriro chaiwo ekuona mafuta.
Kuti vaongorore mashandiro ese echinhu chinoona mafuta, huwandu hwakasiyana hwenitrogen (N2), oxygen (O2), uye carbon monoxide (CO) magasi akaongororwa. Huwandu hwemafuta hwaibva pazvikamu gumi pamiriyoni kusvika pazvikamu mazana mapfumbamwe pamiriyoni (ppm) kuti vaongorore kunzwisisika uye hunhu hwemhinduro yechinhu chinoona. Nguva yekupindura yechinhu chinoona uye nguva yekupora zvinonyorwa patembiricha dzakati wandei uye mwero wehunyoro kuti zvionekwe mashandiro azvo pasi pemamiriro akasiyana-siyana ezvakatipoteredza.
Usati waita bvunzo dzemutemo dzekunzwa gasi, sisitimu yekunzwa gasi inofanira kuita maitiro ekuyera kuti ive nechokwadi chekuti zviyero zvakarurama uye zvakavimbika. Mutsetse wekuyera unobva wagadzirwa nekuisa sensor kuhuwandu hwegasi hunozivikanwa uye zvichibatanidza shanduko yekuramba nemazinga egasi. Mhinduro ye sensor inoongororwa zvichienderana nemitemo yakatarwa yekunzwa gasi kuti ionekwe kururama kwayo uye kuenderana kwayo mukuona carbon monoxide.
