•First example of a wearable trace metal electrochemical sensor is demonstrated.•Real-time monitoring of trace metal in human perspiration is described.•Flexible and robust printable tattoo sensors withstand mechanical stress.•Non-invasive epidermal stripping-voltammetric detection of trace metal is achieved.
A wearable electrochemical sensor for non-invasive monitoring of trace metals in human perspiration is described. The temporary tattoo-based printable stripping-voltammetric sensor has been applied for real-time monitoring of zinc in sweat using a bismuth/Nafion film electrode during physical activity. The Zn temporary tattoo sensor withstands repeated mechanical stress and displays a well-defined Zn response during on-body testing. Such a non-invasive stripping-voltammetric detection could be readily expanded to epidermal measurements of other relevant heavy metals.
