Devices Would Detect Drugs In Sweat
Proposed devices worn on skin detect such substances as methamphetamine, morphine, tetrahydrocannabinol (THC), and cocaine in wearers' sweat and transmits radio signals in response to computer queries. Called Remote Biochemical Assay Telemetering System (R-BATS), commonly referred to as "drug badge," attached to wearer by use of adhesive wristband. Used for noninvasive monitoring of levels of prescribed medications in hospital and home-care settings and to detect overdoses quickly.
