ATMEGA328-BASED SMARTWATCH KEEPS TRACK OF DRUGS IN YOUR SYSTEM BY ANALYZING YOUR SWEAT

Wearables have been part of the medical field for a while now, making the work of medical practitioners easier. They help monitor heart rate, temperature, oxygen levels etc. However, to achieve the mission of personalized medicine, centering on delivering the right drug to the right patient at the right dose, therapeutic drug monitoring solutions are necessary. This has moved engineers from the UCLA Samueli School of Engineering and the Stanford School of Medicine to develop a smartwatch capable of tracking a wearer’s metabolization of medicines, by analyzing their sweat. About the smartwatch, Assistant Professor Sam Emaminejad who is the study lead says :

We wanted to create a wearable technology that can track the profile of medication inside the body continuously and non-invasively…This way, we can tailor the optimal dosage and timing of the intake for each individual. And using this personalization approach, we can improve the efficacy of the therapeutic treatments.

The engineers devised a surface engineering strategy, which enabled them to create a¬†voltammetric¬†sensing interface, featuring an ‚Äúundistorted potential window,‚ÄĚ within which the target electroactive drug‚Äôs voltammetric response is dominant and interference is eliminated, rendering reliable target quantification in noninvasively retrievable biofluids (sweat and saliva).
