Ent\u00e4 jos sykkeen seuraaminen olisi yht\u00e4 helppoa kuin musiikin kuuntelu? Avaruusteknologian kehityksen ansiosta iPhone pystyy pian pit\u00e4m\u00e4\u00e4n sinut ajan tasalla sek\u00e4 suosikkiartisteistasi ett\u00e4 sykkeest\u00e4si.<\/p>\n<\/div>\n

T\u00e4h\u00e4n asti urheilijat ja kuntoilun harrastajat ovat yleens\u00e4 joutuneet k\u00e4ytt\u00e4m\u00e4\u00e4n ep\u00e4mukavia rintakeh\u00e4vy\u00f6j\u00e4, jos he ovat halunneet saada tarkkoja sykemittaustuloksia. Tilanne on kuitenkin muuttumassa, kun sveitsil\u00e4isen CSEM-yrityksen valmistama pieni laite Pulsear tulee markkinoille. Pulsear asennetaan tavallisen kuulokkeen sis\u00e4\u00e4n. Se toimii l\u00e4hett\u00e4m\u00e4ll\u00e4 infrapunasignaaleja korvan kudosten l\u00e4pi.<\/p>\n

Hyvin pieni anturi tallentaa tulokset ja l\u00e4hett\u00e4\u00e4 ne kuulokkeiden johtojen kautta laitteeseen, joka liitet\u00e4\u00e4n puhelimeen. iPhone-sovellus n\u00e4ytt\u00e4\u00e4 sykkeen n\u00e4yt\u00f6ll\u00e4. On my\u00f6s mahdollista verrata yhden p\u00e4iv\u00e4n sykett\u00e4 nostavaa vaellusta tai juoksulenkki\u00e4 aiempaan harjoituskertaan. Sovellusta p\u00e4ivitt\u00e4isiss\u00e4 toiminnoissa ja kuntoilussa testanneet koehenkil\u00f6t antoivat laitteelle korkeat arvosanat.<\/p>\n

T\u00e4m\u00e4 uraauurtava teknologia kehitettiin ESA:lle osana monimutkaista rintakeh\u00e4\u00e4n kiinnitett\u00e4v\u00e4\u00e4 anturia, jolla mitataan astronauttien veren happipitoisuutta. ESA:n teknologiansiirto-ohjelman my\u00f6nt\u00e4m\u00e4n tuen avulla CSEM pystyi sitten kehitt\u00e4m\u00e4\u00e4n Pulsear-prototyypin.<\/p>\n

Vaikka nykyinen versio mittaa vain sykett\u00e4, sit\u00e4 voitaisiin helposti mukauttaa mittaamaan my\u00f6s muita elintoimintoja, kuten veren happipitoisuutta. T\u00e4m\u00e4 avaisi lukuisia l\u00e4\u00e4ketieteellisi\u00e4 sovelluksia. Se voisi esimerkiksi olla k\u00e4ytt\u00e4j\u00e4yst\u00e4v\u00e4llinen tapa seurata keuhkosairauksista k\u00e4rsivi\u00e4 potilaita.<\/p>\n

\u201cVoit vain sanoa: \u2018anna menn\u00e4, kuuntele musiikkia\u2019, ja samalla voit seurata heid\u00e4n elintoimintojaan\u201d, sanoi CSEM:n tohtori Andrea Ridolfi.<\/p>","protected":false},"excerpt":{"rendered":"
