Ukusetyenziswa kwezinto ezintsha ze-thermoelectric kwiindawo eziphambili kuhambela phambili ngokukhawuleza, kuqhutywa ziinguqu eziguqukayo kwisayensi yezinto. Okuphawulekayo kukuba, ukuhlanganiswa okudibeneyo kokuguquguquka kunye nokunciphisa i-aturization kukhulule ubuchwepheshe bokupholisa be-thermoelectric kwimida yezakhiwo eziqinileyo zesiqhelo, ngaloo ndlela kuvula imida emitsha yesicelo kumacandelo amaninzi obuchwephesha obuphezulu:
Izicelo ze-Electronic Skin and Healthcare eziguquguqukayo
Ukuvela kwezinto eziguquguqukayo ze-thermoelectric ezingaphiliyo—ezifana nee-composites ezisekelwe kwi-bismuth telluride (Bi₂Te₃) kunye ne-silver chalcogenides—kuye koyisa urhwebo olude phakathi kokusebenza okuphezulu kwe-thermoelectric kunye nokukhubazeka koomatshini.
Ukunciphisa iiMicroscale Hot-Spot: Iicooler ze-thermoelectric ezisebenzisa iBi₂Te₃ ezincinci kakhulu, iimodyuli zokupholisa ze-thermoelectric (iimodyuli zePeltier) zifikelela ekunciphiseni ubushushu obungaphezulu kwe-10 °C phantsi kombane omncinci wokufaka (umz., 84 mA), kunye nexesha lokuphendula ubushushu elikhawulezayo kakhulu elimalunga ne-25 μs. Oku kwenza ulawulo lobushushu oluchanekileyo nolukwindawo ethile kwiisekethe ezidityanisiweyo ezinamandla aphezulu, ngaloo ndlela kuphucula ukuthembeka kweetship kunye nokuzinza kokusebenza.
Izixhobo zonyango ezinxitywayo nezifakelwayo: Ngenxa yokunamathela kwazo kwizicubu zebhayoloji—ezifana nolusu lwe-elektroniki—izixhobo ze-thermoelectric eziguquguqukayo, izixhobo ze-peltier, (iimodyuli ze-thermoelectric) zisebenza imisebenzi emibini: (i) ukuqokelela amandla obushushu ukusuka kwi-gradient yomzimba ukuya kwi-sensors ze-biomedical ezinamandla aphantsi kakhulu (umz., iimonitha zesantya sentliziyo eziqhubekayo); kunye (ii) ukuvumela ukuva ubushushu okuchanekileyo, okuxazululwe ngokwendawo ukuze kufunyanwe kwangethuba ukudumba okukhoyo, uvavanyo lweengxaki zokuphuma kwegazi emzimbeni, kunye nolawulo olusebenzayo lobushushu kwizixhobo ezifakelwayo kwisizukulwana esilandelayo—kubandakanya i-neural interfaces kunye ne-brain-computer interfaces.
Iindawo Ezingqongileyo Ezigqithisileyo kunye Neenkqubo Zeenqwelo-moya
Ukuvuthwa kwemizi-mveliso kwee-semiconductors zesizukulwana sesithathu ze-wide-bandgap—ngakumbi i-silicon carbide (SiC) kunye ne-gallium nitride (GaN)—kuyandisa ngokuthe ngcembe indlela yokusebenza kwezixhobo ze-semiconductor, ii-thermoelectric modules, ii-TEC modules (ii-peltier modules) kwiimeko ezimandundu.
Ukuva Ubushushu Obuphezulu kunye noLawulo Lobushushu: I-voltage ephezulu yokuqhekeka kwangaphakathi, uzinzo olukhethekileyo lobushushu, kunye nokunyamezela imitha ye-SiC kunye ne-GaN kwenza ukuba kusebenze ngamandla iinkqubo zokuvavanya ubushushu kunye neenkqubo zokulawula ubushushu ezisebenzayo kwiindawo ezibalulekileyo—kuquka amaqonga eenqwelo-moya kunye nokujonga inkqubo yemizi-mveliso enobushushu obuphezulu—apho ukuchaneka okungqongqo, ukuthembeka, kunye nokuphila ixesha elide kubaluleke kakhulu.
Iirobhothi ezikrelekrele kunye nokubona okuchukumisayo
Uyilo lwezinto ezibonakalayo ludlulela ngaphaya kolawulo lobushushu ukuze luxhase inkqubela phambili epheleleyo kwi-elektroniki eguquguqukayo. Umzekelo, abaphandi benze i-active-matrix tactile sensor besebenzisa ii-semiconductors ezibhityileyo kakhulu, ezihambelana noomatshini (umz. i-molybdenum disulfide). Xa idityaniswe kwi-robotic grippers ezithambileyo, le sensor ibona uxinzelelo lwenqanaba elingaphantsi kwe-millipascal—olulingana namandla athambileyo omoya ophuma eluswini lomntu—ngaloo ndlela inika oomatshini ubuchule obufana nobomntu. Ukudibana kokuqonda okuqinileyo kobuchule kunye nolawulo lobushushu oluguquguqukayo kuseka iqonga lezixhobo zesiseko zeenkqubo ze-robotic ezizimeleyo ze-biomimetic kwixesha elizayo.
Uguqulelo lweMizi-mveliso kunye noLawulo lweTekhnoloji yasekhaya
Kwilizwe lasekhaya, imizamo edibeneyo yamaziko ophando kunye nabathathi-nxaxheba kushishino ikhawulezisa utshintsho lwezinto ezintsha zelebhu ukuya kwiimveliso ezithengiswayo. Ityala elimeleyo yiShanghai Institute of Ceramics, iChinese Academy of Sciences, enikeze iilayisenisi ezininzi zeepatenti kwi-thermoelectrics zeplastiki ezingaphiliyo—eziququzelela ukusasazwa kwazo kwi-optical module thermal stabilization, i-advanced chip-level heat dissipation, kunye nezicelo ze-microsensor ezizisebenzisayo. Olu phuhliso lubonisa inkqubela phambili yeTshayina ekuzithembeni kwezobuchwepheshe kwizixhobo ze-semiconductor eziphambili, ukunciphisa ukuxhomekeka kwiikhonkco zokubonelela zangaphandle kunye nokuqinisa amandla asekhaya okuvelisa izinto ezintsha.
