Abstract: The present invention provides a skin patch for measuring a biometric parameter of a bodily fluid. The skin patch comprises a hydrophilic sensing bead and a sensor including at least one electrode embedded within the hydrophilic sensing bead, in which the sensor is configured to obtain data relating to the concentration of the hydrophilic sensing bead relating to the parameter. The skin patch further comprises a transport section for transporting a bodily fluid to contact the hydrophilic sensing bead. The skin patch also comprises a communication unit, which includes an input section communicating with the sensor via a connector, and an output section configured to output the obtained data.
