Spray-coated carbon flower sensors on stretchable substrates detect six biomarkers at sub-nanomolar levels and distinguish ...

Capacitive sensors work by detecting the change of capacitance introduced by the finger touching near the electrode. Such change is so small that detecting it unambiguously is challenging, and has ...

Dispersible electrodes based on gold-coated magnetic nanoparticles modified with DNA can detect microRNA in unprocessed blood samples at extremely low concentrations and over a broad range – a first ...

T his article is a follow-up to the one on SELF capacitance [1], and together, they cover the theories and design guides for the two most popular capacitive sensors, the projected and self capacitive ...

BEIJING, June 11 (Xinhua) -- Researchers have developed a new type of graphene electrode for ultra-sensitive and controllable flexible capacitive pressure sensors. Flexible pressure sensors allow ...

Per- and polyfluoroalkyl substances (PFAS) are persistent pollutants that have contaminated drinking water supplies around the world. Scientists and regulators would like to easily detect these ...

A new, wearable sensor that uses silver nanowires to monitor electrophysiological signals, such as electrocardiographyor electromyography, has been developed by researchers. The new sensor is as ...

Researchers from North Carolina State University have developed a new, wearable sensor that uses silver nanowires to monitor electrophysiological signals, such as electrocardiography (EKG) or ...

A soft, edible electrode made from alginate and polydopamine detects glucose under intestinal conditions, opening a path toward swallowable sensors for diabetes monitoring. (Nanowerk Spotlight) ...
