Abstract: The present disclosure provides a device and system for detecting and/or measuring a constituent of an interstitial fluid from the skin of a subject. The device is a wearable extended gate field effect transistor (EGFET) device comprising a polymeric substrate for fixing to the skin of the subject: an extended gate electrode comprising a first microneedle configured for accessing the interstitial fluid and a first electric contact, wherein the first microneedle and the first electric contact are disposed on the polymeric substrate; and a field effect transistor (FET) associated with the first microneedle through the first electric contact. Further provided are a method for detecting and/or measuring a constituent of an interstitial fluid from the skin of a subject involving the use of the system and a method for fabricating the EGFET device.
