The rapid development of wearable biosensing calls for next‐generation devices that allow continuous, real‐time, and painless monitoring of health status along with responsive medical treatment. Microneedles have exhibited great potential for the direct access of dermal interstitial fluid (ISF) in a minimally invasive manner. Recent studies of microneedle‐based devices have evolved from conventional...

In article number 2108607, Miaomiao Yuan, Hossam Haick, and co‐workers report an innovative, stretchable, skin‐conformal, fast‐response, microneedle, extended‐gate field‐effect transistor biosensor for real‐time detection of sodium in interstitial fluids for minimally invasive health monitoring. High sensitivity, low limit of detection, excellent biocompatibility, and on‐body mechanical...
Sodium is a prominent prognostic biomarker for assessing health status, such as dysnatremia. As of now, detection and monitoring of sodium levels in the human body is carried out by means of laborious and bulky laboratory equipmentand/or by offline analysis of various body fluids. Herein, an innovative stretchable, skin‐conformal and fast‐response microneedle extended‐gate FET biosensor is reported...
