Abstract
Nosivi bežični kemijski senzori omogućavaju neinvazivnu i kontinuiranu analizu uzoraka, što nije moguće postići klasičnim analitičkim metodama i instrumentima. U ovom radu predstavljena su mjerenja provedena kako bi se ustanovio princip djelovanja te mogućnost primjene novog nosivog optičkog senzora u fiziologiji sporta. Kolorimetrijska karakterizacija pH osjetljivog bojila (2-fluoro-4-[4-(2-hidroksietansulfonil)-fenilazo]-6-metoksifenol (GJM-492) imobiliziranog na tekstilu od poliestera, provedena je kako bi se odredila njegova primjenjivost za određivanje pH znoja. Senzor je zasnovan na RFID tehnologiji bežične komunikacije, te bi se ovakva vrsta senzora mogla primjenjivati kao nosivi bežični optički pH kemijski senzor u svrhu poboljšanja učinka sportaša.Wearable wireless chemical sensors allow non-invasive and continuous analysis of samples, which can otherwise not be achieved by conventional analytical methods and instruments. In this work measurments conducted in order to establish the principle of operation and possibility of application of a novel type of wearable optical chemical sensor in sport physiology are presented. Colourimetric characterisation of pH sensitive dye 2-fluoro-4-[4-(2-hydroxyethanesulfonyl)-phenylazo]-6-methoxyphenol (GJM-492) immobilized on a polyester fabric was conducted in order to determine its applicability for sweat pH monitoring. The wireless sensor is based on RFID technology of wireless communication, and this type of sensor could therefore be used as wearable wireless optical pH sensor in order to improve athletes' performance
