Khungu lowuziridwa ndi njoka: tsogolo la ma prosthetics akumva

Munda wa ma prosthetics ndi gawo lofunikira, koma lofunikira, powonetsa momwe ukadaulo ungakulitsire moyo wa omwe akutizungulira. Ngakhale kuti anthu odulidwa ziwalo sangaimire unyinji wa anthu wamba, akupeza phindu la kupita patsogolo kodabwitsa kwaukadaulo komwe kumawonjezera kukhudzidwa kwawo ndi moyo watsiku ndi tsiku, komanso kusintha ntchito zawo zonyozeka, zomwe ena aife timaziwona mopepuka. 

Ma prosthetics masiku ano akugogomezera kwambiri za kukhudza, ndipo kafukufuku kumbuyo kwake akuyesetsa kutengera momwe zimamvera kukhala ndi mkono weniweni, wogwira ntchito, wachilengedwe. 

Njoka ndi Khungu 

"Chikopa cha Viper" chatsopano cha prosthetics ndi chitukuko chomwe chimagwiritsa ntchito njira yofanana ndi ziwalo zomwe zimamva kutentha kwa njoka za njoka; amapanga epidermal wosanjikiza wa ma prostheses omwe amatha kumva kusintha kwa kutentha. Khungu lochita kupanga limeneli silingamezedwe ku zokopa za anthu odulidwa, komanso lingagwiritsidwe ntchito pa mabandeji achipatala kuti azindikire kusintha kwa kutentha, komwe kungasonyeze matenda. 

Momwe Khungu La Prosthetic la Tsogolo Limagwirira Ntchito 

Khungu, kapena "filimu", monga ofufuza ku dipatimenti ya Caltech's Engineering (otsogolera polojekiti) amakonda kuyitcha, amatsanzira ziwalo zozindikira kutentha za njoka yamoto. Njira za ion mu nembanemba ya cell ya dzenje la njoka zam'mimba zimakula panthawi yakusintha kwa kutentha; izi zimathandiza kuti ma ions ayende, ndipo zimayambitsa zikhumbo zomwe zimatsogolera ku zomverera ndi ndemanga za kusintha kwa kutentha mkati mwa njoka. Dongosolo lomwe limagwiritsidwa ntchito pakhungu la prototypal ndilofanana kwambiri, ndipo limagwiritsa ntchito nembanemba ya pectin ndi madzi, zomwe zimapangitsa kuti pakhale mphamvu yamagetsi yofananira ikagwiritsidwa ntchito pama prosthetics.
