This work presents a wearable microfluidic device for sweat analysis. The purpose of this device is to collect sweat from the skin and convey it to the sensor. The device is printed by a 3D printer with Multi-Jet Modelling (MJM) technology using flexible materials. The performance of the microfluidic device in electrochemical sensing of two types of molecular analytes is verified. We investigated the electrochemical measurements of Paracetamol as a model of a drug, and of ferro-ferricyanide as model of ionic analyte. We checked the performance of the device with both unmodified carbon and gold screen-printed electrode. The device is then proposed for several potential analyses in sweat for in-vivo and in-situ applications.
