Mā tēnei pehi i te haruru wera ka whakapai ake i te ōwehenga tohu-ki-haruru (SNR), ka āwhina i te whakaahua taumira teitei i raro i ngā āhuatanga mārama tino iti, korehau rānei.
3. Whakahaere Wera Iti mō ngā Hikohiko Matatau
I te neke haere o ngā pūnga haurua-irahiko i raro i te 3 nm, ka raru te mahi, te pono, me te hua i ngā wāhi wera ā-rohe. Ka tukuna e ngā whakamatao hiko-iti (micro-TEC), ngā kōwae hiko-iti, ngā huānga mico-peltier te whakahaere pāmahana i runga i te mate, i te mate tata rānei me ngā wā urupare i raro i te mirihekona.
• Whakaurunga rauemi hou: I hangaia e tētahi rōpū rangahau i te Harbin Institute of Technology (Shenzhen) tētahi waeine micro-TEC, he waeine micro peltier (pūrere micro peltier) e ahu mai ana i te konupūmā-bismuth, e whakaatu ana i te kaha whakamatao pāmahana rūma pai rawa atu (>500 W/cm³) me te urupare tere. Kua whakamahia angitu hei whakahaere wera kaha o ngā matua waeine microcontroller (MCU).
• Te whakamatao i runga i te maramara me te taumata-wāhanga: Ko ngā Micro-TEC, ngā huānga micro-peltier, ngā kōwae thermoelectric micro, ngā kōwae Micro TEC kua whakauruhia tika ki ngā CPU mahi-teitei, ngā kaituku LiDAR, me ngā kōwae RF mua. Nā te hoahoa hototahi-tapuwae ka taea te whakakore i te werawera i te tauine micron, me te whakarite kia mau tonu te pono o te rorohiko i raro i te kawenga wera tonu.
4. Ngā Pūrere Hauora Koiora me te Aroturukitanga Mekameka Matao
Ka tautokohia e ngā TEC me ngā kōwae TEC (ngā kōwae whakamatao thermoelectric) ngā mahi hauora tino nui mā te hauhake pūngao kore mahi me te whakahaere wera hohe—he mea nui ēnei mō ngā tono ka taea te whakauru me ngā tono e aro ana ki te kawe mahi.
• Te mana whakatō me te whakamatao: I whakaatu ngā kairangahau o MIT i tētahi kiriata hiko tino angiangi, ngāwari hoki i whakatōngia ki raro i te kiri o ngā tauira poaka. Mā te whakamahi i te pikinga pāmahana ~2.5 K i waenga i te kiko o te tinana me te kiri o waho, ka whakakaha tonu te taputapu i tētahi mīhini whakatere manawa mō te iwa marama—e whakamana ana i te mana motuhake o te pūngao koiora-whakauru mō te wā roa.
• Te aroturukitanga mekameka makariri motuhake: I whakamahia ngā tohu tairongo pāmahana e whakauru ana i ngā whakaputa hiko wera (TEG) ki roto i ngā mahi whakahaere kano mRNA a Pfizer. Ka kohia e ēnei pūoko hiko-whaiaro te pūngao wera mai i te rerekētanga pāmahana o roto-o waho o te whare utanga hei whakahaere i te ine waea ahokore—ka whakakore i te whakawhirinakitanga ki te pākahiko me te whakahohe i te tuhi pāmahana tonu, ātete-whakarerekē puta noa i te kawe.
5. Ngā Pūnaha Taiao-Pōuri: Te Rererangi me te Tūhuratanga Moana-Hohonu
Mā te hangarau thermoelectric ka taea te whakahaere i te wera me te hiko, he pakari, kāore he tiaki, i roto i ngā taiao e pakaru ai ngā pūnaha tuku iho—ina koa i raro i te korehau, te pānga o te hihi, te pikinga wera nui rānei.
• Ngā tūāpapa moana hōhonu me ngā tūāpapa āmiomio: I roto i te Whatunga Tirotiro o Mariana Trench e arahina ana e Hapani, ka hurihia e ngā miihini hiko whakamahana ā-pūrua (TEG) te pikinga >340 K i waenga i te wai whakaputa waiariki (~350 °C) me te wai moana taiao (~2 °C) hei mana tonu taumata-kirowatt mō ngā pūnaha ataata HD moana hōhonu. I te wā kotahi, kua whakauruhia ngā hanganga tuanui whakamahana ki roto i te pūrua whakamātautau o te Teihana Wāhi Ātea o te Ao mō te whakaora i te wera para me te whakahaere wera tika.
