Abstract:Conductive polymers are recognized as ideal candidates for the development of noninvasive and wearable sensors for real‐time monitoring of potassium ions (K+) in sweat to ensure the health of life. However, the low ion‐to‐electron transduction efficiency and limited active surface area hamper the development of high‐performance sensors for low‐concentration K+ detection in the sweat. Herein, a wearable K+ sensor is developed by tailoring the nanostructure of polypyrrole (PPy), serving as an ion‐to‐electron tra… Show more
