Temporary Electronic Tattoo for Monitoring ******* Levels Through Sweat
[IMG]http://www.medgadget.com/wp-content/uploads/2016/08/skin-*******-sensor.jpg[/IMG]Breathalyzers, the most widely used **n-invasive tools for measuring blood ******* concentration, are prone to inaccurate results since they can only provide indirect estimates. Although the most accurate technique for measuring blood ******* level is via a blood sample, this requires a finger prick to draw blood. Researchers from the University of California San Diego have engineered a **vel wearable electronic tattoo that senses and measures blood ******* level in sweat and relays this information to a wireless device via an electronic circuit board. The flexible sensor is a **n-invasive, portable, real-time indicator that provides accurate read-outs within 15 minutes.

The tattoo consists of a small hydrogel pilocarpine-eluting ***** and screen-printed electrodes. Pilocarpine stimulates the production of sweat, which interacts with the electrodes that electrochemically detect blood ******* level and relay the data to a flexible electronic circuit board. The circuit board communicates wirelessly with a mobile device, such as a smartphone or laptop.

The device was tested in nine healthy subjects prior to and following ******* consumption, and it was able to detect the rise in etha**l on the skin. The applications for the device include self-monitoring, integration with the ******* ignition interlocks of vehicles, or physician and law enforcement use.
