Abstract The development of wearable biosensors for continuous noninvasive monitoring target biomarkers is limited to assays a single sampled biofluid. An example simultaneous sampling and analysis two different biofluids using epidermal platform demonstrated here. concept successfully realized through sweat stimulation (via transdermal pilocarpine delivery) at an anode, alongside extraction interstitial fluid (ISF) cathode. system thus allows on‐demand, controlled the same time, physically...
Despite tremendous recent efforts, noninvasive sweat monitoring is still far from delivering its early analytical promise. Here, we describe a flexible epidermal microfluidic detection platform fabricated through hybridization of lithographic and screen-printed technologies, for efficient fast sampling continuous, real-time electrochemical glucose lactate levels. This soft, skin-mounted device judiciously merges lab-on-a-chip integrated with miniaturized electronic board wireless data...

Abstract Tracking fluctuations of the cortisol level is important in understanding body's endocrine response to stress stimuli. Traditional sensing relies on centralized laboratory settings, while wearable sensors are limited slow and complex assays. Here, a touch‐based non‐invasive molecularly imprinted polymer (MIP) electrochemical sensor for rapid, simple, reliable stress‐free detection sweat described. The readily measures fingertip via highly selective binding cortisol‐imprinted...
Wearable sensors for noninvasive monitoring of physiological parameters is a growing technology in the clinical field. Especially neonates, development portable and nonharmful devices urgently needed because they cannot provide any feedback about discomfort or health complaints. However, infant monitoring, only wearable measuring physical vital signs have been developed. Here, we describe first chemical sensor newborn monitoring. This fully integrated pacifier operates as wireless device...
While wearable and mobile chemical sensors have experienced tremendous growth over the past decade, their potential for tracking guiding nutrition has emerged only three years. Currently, guidelines from doctors dietitians represent most common approach maintaining optimal status. However, such recommendations rely on population averages do not take into account individual variability in responding to nutrients. Precision recently address large heterogeneity individuals' responses diet, by...
Diabetes prevalence has been rising exponentially, increasing the need for reliable noninvasive approaches glucose monitoring. Different biofluids have explored recently replacing current blood finger-stick strips with painless sensing devices. While sweat received considerable attention, there are mixed reports on correlating results levels. Here, we demonstrate a new rapid and approach that combines simple touch-based fingertip electrochemical sensor algorithm addresses personal variations...
