Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.

The development of nanotechnologies, and the advent of micro/nano-sensors with novel functionalities integrated on flexible substrates, has opened the way to the development of wearable technology. Interest in wearable technology comes from the considerabl ...

The present invention concerns a biosensor (1) comprising: a source element (13); a drain element (17); a semiconductor channel element between the source element (13) and the drain element (17) for forming an electrically conductive channel with adjustabl ...

This paper presents a method to integrate biocompatible passive microfluidic systems within a sensing platform to allow continuous analysis of sweat in a wearable microsystem. The technology is promising for miniaturization of systems to enable access to b ...

Cortisol is a hormone released in response to stress and is a major glucocorticoid produced by adrenal glands. Here, we report a wearable sensory electronic chip using label-free detection, based on a platinum/graphene aptamer extended gate field effect tr ...

Wearable systems could offer noninvasive and real-time solutions for monitoring of biomarkers in human sweat as an alternative to blood testing. Recent studies have demonstrated that the concentration of certain biomarkers in sweat can be directly correlat ...

Ion sensitive field effect transistors (ISFETs) form a very attractive solution for wearable sensors due to their capacity for ultra-miniaturization, low power operation, and very high sensitivity, supported by complementary metal oxide semiconductor (CMOS ...

This paper reports for the first time, smart 3D-Extended-Metal-Gate Ion-Sensitive-Field-Effect-Transistors (3D-EMG-ISFETs), with unique figures of merit: (i) extremely-low-power (down to a record value of 2 pW per sensor under excellent linearity), (ii) al ...

This work presents one of the first low power pH sensing microfluidic chip based on the heterogeneous integration of: (i) high-k FinFET sensors with liquid gate, (ii) miniaturized Ag/AgCl quasi-Reference Electrode and (iii) passive microfluidic. The integr ...

An on-body wearable bio-fluid collection and sensing device including an interface or interface surface comprising at least one biocompatible material for contacting a bodily part; at least one inlet for receiving the bio-fluid, at least one outlet for eva ...

Presented herein are systems and methods for measuring sweat rate of a subject using a wearable system. A sweat rate may be determined automatically based on one or more signals produced by a wetting sensor module in response to a presence of sweat in the ...

Presented herein are devices for collecting and/or channeling a biofluid (e.g., sweat, tears, saliva) and detecting and/or quantifying one or more biomarkers in the biofluid. The biomarker(s) may include, for example, ions, salts thereof, hormones and/or s ...
