Wearable biosensor tattoos monitor sweat to track weight
Taking continuous effort of seamlessly integrating biosensors with human body a leap further, Laboratory for Nanobioelectronics led by Professor Joe Wang, Department of NanoEngineering, has developed biosensor tattoos which monitor electrolytes and metabolite levels in sweat. To access the metabolic health of a wearer, these wearable biosensors have been integrated with multifaceted electrochemical sensors with simple, fairground tattoos that are perfect in monitoring the pH and lactate levels in the sweat. One of the student members of the team, Amay Bandodkar informs that the biosensor tattoos are made with carbon fiber backing which makes them sturdy and flexible to bend with the skin of the wearer in normal course.
A great medical achievement to keep track of weight and daily physical activity levels of a patient, the newly developed biosensor tattoos have been on display at the Research Expo being held at the UC San Diego Jacobs School of Engineering. The researchers are still working on the highly sensitive and accurate biosensor tattoo, one to see how these live though rigorous wear and tear in normal day use, and second to also get the tattoos to detect sodium and ammonia in the sweat.
The biosensor tattoos can be easily disguised, they can either apply directly skin or can even be sewn into clothing. Researchers say, the higher are the quantities of quantities of electrolytes, sodium and ammonia in sweat, the higher is the person’s physical activity and keeping track of these chemicals with biosensor tattoos can reveal the change in person’s weight and stamina etc.
