<prompt> Fingqa isihloko: Ososayensi baye benza umgexo obizwa ngokuthi i-diet choker oqapha konke okuya emphinjeni wakho - futhi okuthumelela isaziso uma udla ngokweqile. I-WearSens iyindandatho yensimbi ezungeza intamo yakho futhi inenzwa esebenzisa ukudlidliza okusephuleni kwakho ukuze ikutshele ukuthi udla futhi uphuza nini. Abacwaningi abasungula le divayisi bayixhumanise nesicelo se-smartphone esizwakalayo uma udlula umkhawulo wakho wekhalori wansuku zonke. Ososayensi baye bahlanganisa i-WearSens, indandatho yensimbi ezungeze intamo ngenhla ukuze iqaphe ukudla, ne-app ye-smartphone ebala ama-calorie. Iphinde ikwazise uma udla kakhulu ukudla okungafanele. Le divayisi yasungulwa onjiniyela baseYunivesithi yaseCalifornia, eLos Angeles futhi kuze kube manje ukuhlolwa kwabantu abangu-30 kubonisa ukuthi iyasebenza. Kodwa ukusabela kwezinye izindawo kuye kwahluka futhi amanye amawebhusayithi ezobuchwepheshe akufanisa nekhola yokugwinya, nakuba inganciphi uma udla kakhulu. Enye ingosi, i-Bustle.com, yabiza le nto ngokuthi ubuchwepheshe obugqokekayo obuyinqaba kunabo bonke esibubonile kuze kube manje. Ithimba le-UCLA lathi i-WearSens isebenza ngoba ukudla ngakunye kwenza iphethini ehlukile yokudlidliza entanyeni ngakho-ke idivayisi iyakwazi ukuthola ukuthi yini oyidlayo isebenzisa inzwa ye-piezoelectric, elinganisa ushintsho ekucindezelweni noma emandleni. Ekuvivinyweni kwemenyu elinganiselwe iye yaqagela ngokunemba ngamaphesenti angu-90 umehluko phakathi kokudla okuqinile noketshezi - ngisho nomehluko phakathi kweziphuzo ezishisayo noma ezibandayo. Umshini ubuye ukwazi ukuhlukanisa phakathi kokudla okuqinile nokuthambile cishe izikhathi ezingamaphesenti angu - 75, ngokusho kokutholakele ephephabhukwini i - IEEE Sensors. UMajid Sarrafzadeh, ongumsunguli we-WearSens, wathi: Izindlela eziningi zokudla ezisekelwe ekubhaleni phansi lokho okudlayo. Kodwa le ndlela inokuhambisana okuphansi ngakho-ke besifuna ukunqoba lezi zinkinga futhi besifuna ukwenza okuthile okwenziwa yi-pedometer ngomsebenzi. Ososayensi banethemba lokuthi lobu buchwepheshe buzokutshela abasebenzisi uma bedla izinhlobo ezingalungile zokudla isithombe sefayela Embonisweni othunyelwe ku-YouTube, idivayisi ibuza iminyaka yomsebenzisi, ukuphakama, isisindo kanye...  <response>: Ososayensi basungula umgexo obizwa ngokuthii-choker yokudlaukuze usize umuntu ukuba anciphise umzimba. Ochwepheshe bahlanganisa insimbi ye-WearSens nohlelo lokusebenza lwe-smartphone ukuze bakhe umkhiqizo. Ubuchwepheshe obusezingeni eliphezulu buthumela isaziso uma abasebenzisi beqala ukudla ngokweqile.
