The current methodology for estimat

The current methodology for estimating sodium in the perspiration relies on collecting sweat via Macroducts sweat collection systems followed by lab-based analysis of the collected fluid(Lee et al., 2010). However, such a protocol has several shortcomings for routine operation (Schazmann et al., 2010). Theseinclude (i) a large sweat collection system that is uncomfortable towear thus hindering wearer's routine, (ii) bulky centralizedexpensive instrumentation for sweat analysis that is incompatiblewith on-body testing and (iii) compromised accuracy due toevaporation of the sweat samples during their transport.Such drawbacks can be addressed using wearable sensors.Diamond's team demonstrated a wearable waistband sodiumsensor for on-body potentiometric monitoring of sodium(Schazmann et al., 2010). Additional efforts aimed at on-bodymonitoring of other electrolytes included measurements of sweatchloride (Gonzalo-Ruiz et al., 2009), ammonium (Guinovart et al.,2013a), potassium (Guinovart et al., 2013b) and pH (Bandodkaret al., 2013a) in human perspiration using disposable strip, textilebased, and tattoo-like ISE, respectively. Parallel activity has beendevoted lately towards the development of portable wirelesstransceivers for potentiometric sensors (Novell et al., 2013; Fayet al., 2011). However these devices have not been applied for onbody electrolyte monitoring
