Ua makemake nui ʻia nā mea uila uila hiki ke hoʻohana ʻia no ka hoʻokō ʻana i ka hoʻokele olakino pilikino.Eia nō naʻe, hiki i ka hapa nui o nā mea uila uila i hōʻike ʻia i kēlā me kēia manawa ke kuhikuhi i kahi hōʻailona physiological hoʻokahi a i ʻole nalo i nā kikoʻī kikoʻī o nā hōʻailona, ​​​​e alakaʻi ana i kahi loiloi olakino.Eia kekahi, ʻo ka textiles me ka waiwai maikaʻi a me ka hōʻoluʻolu e mau nō ka paʻakikī.Maʻaneʻi, hōʻike mākou i kahi pūʻulu ʻike ʻike triboelectric āpau-textile me ka ʻike kiʻekiʻe a me ka hōʻoluʻolu.Hōʻike ia i ka naʻau puʻe (7.84 mV Pa−1), ka manawa pane wikiwiki (20 ms), kūpaʻa (> 100,000 cycles), ka bandwidth hana ākea (a hiki i ka 20 Hz), a me ka holoi ʻana i ka mīkini (> 40 holoi).Ua humuhumu ʻia nā TATSA i hana ʻia i nā ʻāpana like ʻole o nā lole e nānā i nā nalu pulse arterial a me nā hōʻailona hanu i ka manawa like.Ua hoʻomohala hou mākou i kahi ʻōnaehana nānā olakino no ka loiloi lōʻihi a me ka noinvasive o ka maʻi cardiovascular a me ka maʻi apnea moe, e hōʻike ana i ka holomua nui no ka loiloi quantitative o kekahi mau maʻi maʻi.

Hōʻike nā mea uila hiki ke hoʻohana ʻia i kahi manawa hoihoi ma muli o kā lākou noi hoʻohiki i ka lāʻau lapaʻau pilikino.Hiki iā lākou ke nānā i ke kūlana olakino o ke kanaka ma ke ʻano hoʻomau, ka manawa maoli, a me ke ʻano ʻole (1–11).ʻO ka puʻupuʻu a me ka hanu, ʻo ia nā mea koʻikoʻi ʻelua o nā hōʻailona koʻikoʻi, hiki ke hāʻawi i kahi loiloi pololei o ke kūlana physiological a me nā ʻike kupaianaha i ka ʻike a me ka wānana o nā maʻi pili (12-21).I kēia lā, ʻo ka hapa nui o nā mea uila hiki ke hoʻohana ʻia no ka ʻike ʻana i nā hōʻailona physiological maʻalahi e pili ana i nā substrates ultrathin e like me polyethylene terephthalate, polydimethylsiloxane, polyimide, aniani, a me ke silikoni (22-26).ʻO kahi drawback o kēia mau substrates no ka hoʻohana ʻana i ka ʻili aia ma kā lākou papa planar a paʻa.ʻO ka hopena, koi ʻia nā lipine, Band-Aids, a i ʻole nā ​​mea hana mīkini ʻē aʻe e hoʻokumu i kahi pilina paʻa ma waena o nā mea uila hiki ke hoʻohana a me ka ʻili kanaka, hiki ke hoʻonāukiuki a me ka pilikia i ka wā lōʻihi o ka hoʻohana ʻana (27, 28).Eia kekahi, ʻo kēia mau substrates ka maikaʻi ʻole o ka ea permeability, ka hopena i ka ʻeha ke hoʻohana ʻia no ka nānā ʻana i ke olakino lōʻihi.No ka hoʻohaʻahaʻa ʻana i nā pilikia i ʻōlelo ʻia ma luna o ka mālama olakino, ʻoi aku hoʻi i ka hoʻohana ʻana i kēlā me kēia lā, hāʻawi nā textiles akamai i kahi hopena hilinaʻi.Loaʻa i kēia mau textiles nā hiʻohiʻona o ka palupalu, ke kaumaha māmā, a me ka hanu a, no laila, hiki ke ʻike i ka hōʻoluʻolu i nā mea uila uila.I kēia mau makahiki i hala iho nei, ua hoʻolaʻa ʻia nā hana koʻikoʻi e hoʻomohala i nā ʻōnaehana i hoʻokumu ʻia i ka textile i nā mea ʻike makaʻala, ka ʻohi ikehu, a me ka mālama ʻana (29–39).ʻO ka mea nui, ua hōʻike ʻia ka noiʻi kūleʻa e pili ana i ka fiber optical, piezoelectricity, a me ka resistivity-based smart textiles i hoʻohana ʻia i ka nānā ʻana i ka pulse a me nā hōʻailona hanu (40-43).Eia naʻe, he haʻahaʻa haʻahaʻa ka naʻau o kēia mau textiles akamai a me kahi ʻāpana nānā hoʻokahi a ʻaʻole hiki ke hana ʻia ma ke ʻano nui (papa S1).I ka hihia o ke ana pulse, paʻakikī ka ʻike kikoʻī e hopu ma muli o ka nawaliwali a me ka wikiwiki o ka loli ʻana o ka pulse (e laʻa, kona mau hiʻohiʻona), a no laila, koi ʻia ka ʻike kiʻekiʻe a me ka hana pane alapine kūpono.

I loko o kēia haʻawina, hoʻolauna mākou i kahi triboelectric all-textile sensor array (TATSA) me ka naʻau kiʻekiʻe no ka hopu ʻana i ka epidermal subtle pressure, i ulana ʻia me nā kaula conductive a me ka nylon i loko o kahi stitch cardigan piha.Hiki i ka TATSA ke hāʻawi i ka naʻau kiʻekiʻe (7.84 mV Pa−1), ka manawa pane wikiwiki (20 ms), ke kūpaʻa (> 100,000 cycles), ka bandwidth hana ākea (a hiki i ka 20 Hz), a me ka holoi ʻana i ka mīkini (> 40 holoi).Hiki iā ia ke hoʻohui pono iā ia iho i nā lole me ka noʻonoʻo, hōʻoluʻolu, a me ka hoʻopiʻi nani.ʻO ka mea nui, hiki ke hoʻokomo pono ʻia kā mākou TATSA i nā wahi like ʻole o ka lole e pili ana i nā nalu pulse ma ka ʻāʻī, lima lima, manamana lima, a me nā kuʻekuʻe wāwae a me nā nalu hanu i ka ʻōpū a me ka umauma.No ka loiloi i ka hana maikaʻi loa o ka TATSA i ka manawa maoli a me ka nānā ʻana i ke olakino mamao, hoʻomohala mākou i kahi ʻōnaehana nānā olakino naʻauao pilikino e hoʻomau a mālama i nā hōʻailona physiological no ka nānā ʻana i ka maʻi cardiovascular (CAD) a me ka loiloi o ka maʻi apnea hiamoe (SAS). ).

E like me ka mea i hōʻike ʻia ma ka Fig. 1A, ua humuhumu ʻia ʻelua TATSA i loko o ka pahu a me ka umauma o kahi pālule e hiki ai i ka nānā ikaika a me ka manawa like o ka pulse a me nā hōʻailona hanu, kēlā me kēia.Ua hoʻouna ʻia kēia mau hōʻailona physiological ma ke kelepona ʻole i ka polokalamu kelepona paʻalima akamai (APP) no ka nānā hou ʻana i ke kūlana olakino.Hōʻike ka Figure 1B i ka TATSA i humuhumu ʻia i loko o kahi ʻāpana lole, a hōʻike ka inset i ka ʻike nui ʻana o ka TATSA, i ulana ʻia me ka hoʻohana ʻana i ke kaula conductive hiʻohiʻona a me ke kaula nylon pāʻoihana i hui pū ʻia i loko o kahi pahu cardigan piha.Hoʻohālikelike ʻia me ka humuhumu maʻamau, ʻo ke ʻano hana maʻamau a maʻamau, ua koho ʻia ka hili cardigan piha no ka mea ʻo ka pilina ma waena o ke poʻo loop o ke kaula conductive a me ke poʻo humu kuʻi pili o ke kaula nylon (fig.

No ke kālailai ʻana i ke ʻano hana o ka TATSA, me kona ʻano mechanical a me ka uila, ua kūkulu mākou i kahi hoʻohālike geometric knitting o ka TATSA, e like me ka mea i hōʻike ʻia ma ka Fig. 2A.Me ka hoʻohana ʻana i ke kuʻikuʻi cardigan piha, hoʻopili ʻia nā wili conductive a me nā nylon i nā ʻano o nā ʻāpana loop i ka papa a me ka ʻaoʻao wale.Hoʻokahi hanana loop (fig.

Wahi a ka AATCC Test Method 135-2017, ua hoʻohana mākou i ka TATSA a me ka ballast lawa e like me ka ukana 1.8-kg a laila hoʻokomo iā lākou i loko o kahi mīkini laundering kalepa (Labtex LBT-M6T) e hana i nā pōʻai holoi holoi mīkini.A laila, hoʻopiha mākou i ka mīkini holoi me 18 mau galani wai ma 25 ° C a hoʻonohonoho i ka mea holoi no ke kaʻina holoi holoi i koho ʻia (ka wikiwiki hoʻonāukiuki, 119 paʻi i kēlā me kēia minuke; ka manawa holoi, 6 min; ka wikiwiki milo hope, 430 rpm; hope loa. manawa milo, 3 min).ʻO ka mea hope loa, ua kau ʻia ka TATSA ma kahi maloʻo i ka ea mālie ma ka lumi wela ʻaʻole i kiʻekiʻe ma mua o 26°C.

Ua aʻo ʻia nā kumuhana e moe i kahi kūlana ma luna o kahi moe.Ua kau ʻia ka TATSA ma nā kahua ana.I ka manawa i noho ai nā kumuhana i kahi kūlana maʻamau, mālama lākou i kahi kūlana hoʻomaha loa no 5 a 10 min.A laila hoʻomaka ke ana ʻana o ka hōʻailona pulse.
