Ülevaade
Uurimisgrupi teadustöö eesmärgiks on välja töötada paindlikke ja uudseid sensortehnoloogiaid ja algoritme:• Ureemiliste toksiinide eemaldamise jälgimiseks reaalajas. Mõõdetud parameetrid võimaldavad hinnataerinevate ureemiliste toksiinide kontsentratsioone reaalajas ilma vereproove võtmata ning seega aitab saadaparemini tagasisidet ravi (n neeruasendusravi) kohta ning kohandada raviviise vastavalt patsientide vajadustega.• Isikustatud ja targa töörõiva loomiseks, mis töörõivasse integreeritud sensorite ja uudsete algoritmide abil looksväärtuslikke andmeid tööliste asukohast, kõnnimustritest, füüsilisest aktiivsusest, energiakulust jafüsioloogilisest seisundist.• Uuenduslike psühhofüsioloogiliste meetodite väljatöötamine, et hinnata inimeste emotsionaalset vastusterinevatele (elu)keskkondadele (nt turvalised, mugavad, stressirohked, ülestimuleerivad või ebaatraktiivsed).
