[4][5] Development of devices, sensing techniques and biomarker identification in sweat continues to be an expanding field for medical diagnostics and athletics applications.
In-vivo and in-vitro studies from this time period, and even those continuing today, have identified numerous structural nuances and new molecules present within sweat.
Recently several efforts[18] have been made to develop low cost polymer based continuous perspiration monitoring devices and are in early stages of commercialization.
[19] More recently, startup companies such as Xsensio have begun developing products targeted towards the consumer, healthcare and athletics market for sweat diagnostics.
[20] Temporary tattoo-based sweat diagnostic tools[21] have been demonstrated by Dr. Joseph Wang's group from University of California, San Diego.
