Hei te okana nui rawa atu o te tinana tangata, ehara i te mea ko ngā mahi matua o te kiri tangata ko te tiaki, te huna me te manawa anake, engari he pūnaha somatosensory nui hoki mō te taunekeneke me te whakawhitiwhiti kōrero i waenga i te tangata me te ao rauemi. I ngā tau tata nei, kua nui te hiahia o ngā kairangahau ki te whanaketanga o te kiri hiko bionic, ā, he whānuitia ana tono i roto i te aroturuki hauora whaiaro e taea ana te mau, te prosthesis atamai me te karetao, te taunekeneke tangata-rorohiko me te matauranga horihori.

I runga i ngā momo tikanga rongo ā-tinana rerekē, ka taea te whakarōpū i te kiri hiko ki ngā momo piezoresistive, capacitive, piezoelectric me te triboelectric. Ka kitea, ka inehia hoki e te kiri hiko ngā momo whakaohooho taiao, tae atu ki te pāmahana, te haumākū, te pēhanga, te wiri me te pā, ā, ka hurihia hei pāoro hiko wā-tūturu me te tirohanga. Ko te mana waku he momo whakamahi i te whakapā hiko me te pānga hononga o te whakaawe hiko, ka taea te huri i te pūngao miihini utu nui ki te pūngao hiko me te urunga ki te hangarau pūngao hou, he iti te utu, he māmā te hanganga, he watea te whakamahinga, he whiriwhiri rauemi, he pai te hurihanga, me ētahi atu. I roto i te mara o te pūtake hiko mau me te pūoko tuku hiko, he whānui te tirohanga tono, koinei te whiringa pai mō te momo kiri hiko motuhake.

Ko te ngāwari, te toronga, te aro, te urutau me te pakari ā-pūkaha ngā huarahi rangahau tino noa o te kiri hiko i tēnei wā, he ngāwari hoki te whakatinana. I ngā tau tata nei, hei whakapai ake i te mahi whānui o te kiri hiko, kua āta rangahauhia ngā mahi motuhake o te kiri hiko, pērā i te hangarua, te whakaora-ā-roto, te mahara āhua, te hikohiko me te kanapa ā-pūkaha. Ahakoa te arotau tonu me te whakapai ake i ngā āhuatanga o runga ake nei, kua warewarehia te whakamarie, te haumaru me te tiaki taiao o te kiri hiko, ā, he nui te whakararuraru i te whakamahinga mahi o te kiri hiko. Nō reira, me manawa, me pirau, me patu huakita te kiri hiko me te whakamarie me te mahi tino pai. He mahi nui te uruhanga hau hei whakatikatika i te taurite wera me te haumākū me te whakatutuki i te whakawhiti hau i waenga i te tinana tangata me te taiao o waho. Heoi, ko te nuinga o ngā kiri hiko mahi teitei KA WHAKAMAHI i ngā kiriuhi hei irahiko, hei papa rānei, ka taea te whakararu i te kiri, tae atu ki te mumura me te mākūkū. Hei tāpiri, ko te pa roa i waenga i te kiri-e me te kiri tangata he reo pai mō te tipu o te moroiti, nō reira he mea nui ngā āhuatanga patu huakita mō te kiri-e hei aukati i te tipu o te huakita me te ārai i te mate huakita. Hei tāpiritanga, ko te nuinga o ngā rauemi kāore e taea te whakakore noa, ā, i te mutunga o tō rātou oranga whai hua, ka noho hei para hiko, ka kino rānei ki te tinana tangata, ka poke rānei i te taiao.

Nō nā tata nei, i hangaia e te rōpū rangahau o te Beijing Institute of Nanometer Energy and Systems, Chinese Academy of Sciences tētahi kiri hiko nanofiber katoa-ā-manawa, pirau-koiora, huakita, me te mana-ake, e hangai ana ki te nanogenerator waku, e whakatutuki ana i te kohikohinga pūngao miihini me te rongo-ake i te āhua o te tinana tangata me ngā tohu nekehanga hononga. Mā te polylactic acid/glycolic acid copolymer (PLGA) me te polyvinyl alcohol (PVA) nanofibers membrane hei paparanga hiko me te papa me ngā nanowires hiriwa (AgNW) hei takawaenga, i hangaia me te whatunga nanofibers maha-paparanga me te maha o ngā hanganga toru-ahu o ngā kōhao micro-nano e hangai ana ki te kaha waku kiri hiko, ka whai hua mō te kiri tinana tangata me te taiao o waho o te whakawhiti wera. I te wa ano, he tino pai ngā āhuatanga huakita o te kiri hiko, ka taea te aukati i te tipu o Escherichia coli me Staphylococcus aureus, me te ārai i te mate kitakita. Mā te whakarerekē i te rahi me te taurite o te PLGA me te PVA pirau-koiora, ka taea te whakarerekē i te huringa pirau o te kiri hiko ki ētahi rā ki ētahi wiki. Hei tāpiritanga, me te mahi putanga mōrahi o te 130 mW /m2 me te aro o te urupare ngaohiko o te 0.011 kPA-1, ka taea e te kiri hiko te whakatutuki i te aroturuki whaiaro-kore-whakaekenga o ngā tohu ā-tinana (pēnei i ngā whakaaturanga iti, te pā o te manawa, te manawa me ngā mahi) me ngā nekehanga hononga (pēnei i ngā pona, ngā tuke, ngā turi me ngā pona waewae) o te tinana tangata. Ka whakaratohia e tēnei mahi he rautaki rangahau kāore i kitea i mua mō te whakawhanake i te kiri hiko maha-mahi. Ko ngā hua mō te taitara "He kiri hiko manawa, pirau-koiora, huakita, me te whaiaro-whakakaha -e hangai ana ki ngā nanogenerators triboelectric nanofiber katoa", i whakaputaina i roto i te Science Advances.
