Kev siv cov khoom siv thermoelectric tshiab hauv cov cheeb tsam tshiab tau nce qib sai sai, uas tau tsav los ntawm kev hloov pauv hauv kev tshawb fawb txog cov ntaub ntawv. Qhov tseem ceeb, kev sib koom ua ke ntawm kev ywj pheej thiab kev ua kom me me tau tso cov thev naus laus zis thermoelectric txias los ntawm cov kev txwv ntawm cov qauv ruaj khov ib txwm muaj, yog li qhib cov ciam teb tshiab ntawm kev siv thoob plaws ntau lub lag luam high-tech:

Cov Tawv Nqaij Hluav Taws Xob thiab Kev Kho Mob uas Yooj Yim Siv Tau

Qhov tshwm sim ntawm cov khoom siv thermoelectric inorganic flexible thermoelectric — xws li bismuth telluride (Bi₂Te₃)-based composites thiab silver chalcogenides — tau kov yeej qhov kev lag luam ntev ntawm kev ua tau zoo thermoelectric siab thiab kev hloov pauv kho tshuab.

Kev Txo Qhov Kub Kub Me Me: Cov khoom siv thermoelectric txias uas siv Bi₂Te₃ nyias heev, cov thermoelectric txias modules (Peltier modules) ua tiav qhov kub txo qis tshaj 10 °C nyob rau hauv qhov tsawg kawg nkaus tam sim no (piv txwv li, 84 mA), nrog rau lub sijhawm teb thermal sai heev ntawm kwv yees li 25 μs. Qhov no ua rau muaj kev tswj hwm thermal meej, hauv zos rau cov circuits sib xyaw ua ke muaj zog, yog li ua kom muaj kev ntseeg siab ntawm cov chip thiab kev ruaj khov ua haujlwm.

Cov Khoom Siv Kho Mob Uas Hnav Tau Thiab Muab Tso Rau Hauv: Vim lawv qhov kev sib txuas ua ke rau cov ntaub so ntswg hauv lub cev—zoo ib yam li daim tawv nqaij hluav taws xob—cov khoom siv thermoelectric uas yooj ywm, cov khoom siv peltier, (thermoelectric modules) ua haujlwm ob txoj haujlwm: (i) sau cov zog thermal los ntawm lub cev-ambient gradients los ua lub zog ultra-low-power biomedical sensors (piv txwv li, cov ntsuas lub plawv dhia tas mus li); thiab (ii) ua kom muaj kev ntsuas kub siab, qhov chaw daws teeb meem thermal rau kev kuaj pom thaum ntxov ntawm qhov mob hauv zos, kev ntsuam xyuas cov ntshav peripheral ...

Ib puag ncig hnyav thiab cov txheej txheem aerospace

Kev loj hlob ntawm kev lag luam ntawm tiam peb-tiam dav-bandgap semiconductors—tshwj xeeb tshaj yog silicon carbide (SiC) thiab gallium nitride (GaN)—tab tom nthuav dav lub hnab ntawv ua haujlwm ntawm cov khoom siv semiconductor, thermoelectric modules, TEC modules (peltier modules) mus rau hauv cov xwm txheej hnyav.

Kev Ntsuas Kub thiab Kev Tswj Kub: Lub zog hluav taws xob tawg siab, kev ruaj khov thermal zoo heev, thiab kev kam rau hluav taws xob ntawm SiC thiab GaN ua rau muaj kev ua haujlwm zoo ntawm kev ntsuas kub thiab cov txheej txheem tswj thermal hauv cov chaw tseem ceeb - suav nrog cov platform aerospace thiab kev saib xyuas cov txheej txheem kev lag luam kub siab - qhov twg qhov tseeb, kev ntseeg siab, thiab lub neej ntev yog qhov tseem ceeb.

Kev Txawj Ntse Robotics thiab Tactile Perception

Cov khoom siv tshiab nthuav dav tshaj qhov kev tswj hwm kub kom txhawb nqa kev nce qib hauv cov khoom siv hluav taws xob uas yoog tau. Piv txwv li, cov kws tshawb fawb tau tsim lub sensor tactile uas siv ultrathin, ua raws li kev siv tshuab ob-seem semiconductors (piv txwv li, molybdenum disulfide). Thaum muab tso rau hauv cov robotic grippers mos, lub sensor no ntes tau cov kev cuam tshuam siab hauv qab millipascal-sib npaug rau lub zog maj mam ntawm huab cua ntawm daim tawv nqaij tib neeg-yog li ua rau cov tshuab muaj kev paub zoo li tib neeg. Kev sib koom ua ke ntawm kev pom kev tactile siab zoo li no nrog kev tswj hwm thermal hloov kho tau tsim kom muaj lub hauv paus kho vajtse rau yav tom ntej biomimetic, autonomous robotic systems.

Kev Txhais Lus Hauv Kev Lag Luam thiab Kev Tswjfwm Hauv Tebchaws Txog Kev Siv Tshuab

Hauv tebchaws, kev sib koom tes ua ke los ntawm cov tsev tshawb fawb thiab cov neeg koom nrog hauv kev lag luam tab tom ua kom nrawm dua kev hloov pauv ntawm cov khoom siv hauv chav kuaj mus rau hauv cov khoom lag luam uas muaj peev xwm ua lag luam. Ib qho piv txwv sawv cev yog Shanghai Institute of Ceramics, Chinese Academy of Sciences, uas tau tso cai ntau daim ntawv pov thawj ntawm cov yas inorganic thermoelectrics - pab txhawb lawv txoj kev xa mus rau hauv optical module thermal stabilization, advanced chip-level heat dissipation, thiab tus kheej-powered microsensor daim ntawv thov. Cov kev txhim kho no qhia txog Tuam Tshoj txoj kev vam meej mus rau kev siv thev naus laus zis hauv cov ntaub ntawv semiconductor siab heev, txo kev vam khom rau cov saw hlau xa khoom txawv teb chaws thiab txhawb nqa lub peev xwm hauv tebchaws rau kev tsim kho tshiab.
