SFU researcher Woo Soo Kim is part of an international research team developing a low-cost 3D-printed wearable sweat sensor
According to Kim, innovations in technology design over the past decade have seen rapid advances in wearable sensors, including sweat sensors
Unlike other biological fluids such as saliva or blood that are collected and tested, the method is non-invasive and requires no assistance
"The chemical composition and physical information extracted from sweat is very valuable in reflecting human health," Kim said
While there are a growing number of low-cost wearable sensors that can collect and analyze sweat to assess a person's health, Kim's 3D printed models integrate mechanically flexible electrochemical sensors and wireless communication capabilities
Typically, the sensor can be attached to the skin using flexible materials such as foam, fabric, flexible plastic or rubber, and ideally, powered by a wireless charger
Kim noted that sweat metabolites can provide important information that can be effectively used to assess the wearer's overall health
