Masayendisiti akagadzira chitsva chechipfuva-laminated, ultrathin, 100 muzana inotambanuka mwoyo inonzwa mudziyo wemagetsi (e-tattoo) kutarisa kushanda kwemoyo. Chishandiso chinogona kuyera ECG, SCG (seismocardiogram) uye nguva yemwoyo yemwoyo nenzira kwayo uye nekuenderera mberi kwenguva yakareba yekutarisa. ropa dzvinyiriro.
Chirwere chemwoyo (s) ndicho chikonzero chikuru chekufa pasi rose. Monitoring kushanda kwemwoyo wedu kunogona kubatsira kusvika pamwero wakati kudzivirira zvirwere zvemwoyo. ECG (electrocardiogram) bvunzo inoyera kuita kwemagetsi emwoyo yedu nekuyera kurova kwemoyo uye mutinhimira kutiudza kana moyo wedu uri kushanda zvakanaka. Imwe bvunzo inodaidzwa kuti SCG (seismocardiography) iaccelerometer sensor-based method iyo iri kushandiswa kurekodha kuzunguzika kwemoyo nekuyera kuzunguzika kwechipfuva kunokonzerwa nekurova kwemoyo. SCG iri kuwedzera kukosha mukiriniki sechimwe chiyero pamwe chete neECG yekutarisa uye kuona kusagadzikana kwemoyo nekuvandudzika kwechokwadi uye kuvimbika.
Zvishandiso zvinopfekwa senge kugwinya uye matracker ehutano zvave nzira inovimbisa uye yakakurumbira yekutarisa hutano hwedu. Nekutarisa mabasa emoyo, mashoma maturusi akapfava aripo anoyera ECG. Nekudaro, masensa eSCG aripo nhasi akavakirwa pane yakasimba accelerometers kana isinga tambanuke membranes ichiita kuti ive yakakura, isingaite uye kusagadzikana kupfeka.
Muchidzidzo chitsva chakaburitswa muna Chivabvu 21 mukati Yepamberi Sayenzi, vatsvakurudzi vanotsanangura chigadzirwa chitsva chinogona kuiswa pachipfuva chemunhu (saka chinonzi se e-tattoo) uye kuongorora mashandiro emwoyo nekuyera ECG, SCG uye nguva dzemoyo. Ichi chakasarudzika mudziyo chakanyanya kutetepa, chakareruka, chinotambanuka uye chinogona kuiswa pamusoro pemoyo wemunhu pasina kudiwa tepi kwenguva yakareba pasina kukonzera marwadzo kana kusagadzikana. Mudziyo uyu wakagadzirwa nenyoka mesh yemashizha anotengeswa epiezoelectric polymer anonzi polyvinylidene fluoride nekushandisa nzira yekugadzira yakapfava, isingadhuri. Iyi polymer ine yakasarudzika pfuma yekugadzira yemagetsi kuchaja mukupindura kune mechanic kusagadzikana.
Kutungamira mudziyo uyu, ye3D mufananidzo yekubatanidza nzira inoburitsa mafambiro echipfuva anobva mukufema uye kufamba kwemoyo. Izvi zvinobatsira kuwana yakaringana yekunzwa nzvimbo yechipfuva kudengenyeka kukwidza mudziyo. Iyo yakapfava SCG sensor inosanganisirwa nema electrode egoridhe anotambanuka pachinhu chimwe chete ichigadzira maviri maviri mode mudziyo unogona kuyera ECG neSCG nekushandisa electro- uye acoustic cardiovascular sensing (EMAC). ECG inogara ichishandiswa kutarisa mwoyo wemunhu, asi kana ichibatanidzwa neSCG zviratidzo zvekurekodhwa, kururamisa kwayo kunowedzera kuvandudzwa. Uye, zvakaonekwa kuti nguva ye systolic ine hukama hwakasimba hwakaipa ne BP, nokudaro BP inogona kufungidzirwa pachishandiswa mudziyo uyu. Kubatana kwakasimba kwakaonekwa pakati penguva yesystolic uye systolic / diastolic yeropa. Imwe smartphone inopa simba ichi chiri kure.
Iyo itsva yechipfuva-yakaiswa mudziyo inotsanangurwa muchidzidzo chezvino inopa nzira iri nyore yekutarisa kukwira kweropa nguva dzose uye isina-invasively. Ichi chishandiso chinonzi ultrathin, ultralight, soft, 100 percent stretchable mechano-acoustic sensor iyo ine high senitivity uye inogona kugadzirwa nyore nyore. Zvipfeko zvakadaro zvinogona kupfekwa kutarisa kushanda kwemoyo pasina kushanya kwachiremba zvinogona kunge zvichivimbisa kudzivirira zvirwere zvemoyo.
