University of California San Diego researchers say their fingertip sweat sensor can accurately detect levels of levodopa, a common medication to treat Parkinson’s Disease symptoms, in sweat.

At the University of California, San Diego, Professor Joseph Wang and his team have developed a touch-based fingertip sweat monitor capable of measuring levels of levodopa, a Parkinson’s medication, directly from sweat. Their goal is to build a revolutionary “closed-loop” system that could assist physicians in precise medication dosage delivery, enabling patients to manage their symptoms more effectively.

Today, we sit down with Shichao Ding, a postdoctoral researcher at UC San Diego, to explore how his team’s innovative electronic finger wrap is revolutionizing health monitoring by analyzing biomarkers from fingertip sweat and generating its power—all without the need for invasive procedures.

Now, let’s continue with today’s episode.

The team led by Yuehe Lin from Washington State University and Joseph Wang from University of California San Diego present an epidermal sensing platform enhanced with single-atom materials (SAMs) designed for flexible and orthogonal electrochemical detection of UA. They designed and synthesized an SAM with Fe-N5 active sites to boost the electrochemical sensing signals, integrating it with laser-engraved graphene (LEG) to fabricate a wearable SAM-based UA patch sensor. This design provides superior UA detection performance compared to sensors based on conventional nanomaterials.

New technology could make it significantly easier to monitor patients’ vital health signs.

Engineers at the University of California San Diego have developed an electronic finger wrap that monitors important chemical levels — such as glucose, vitamins and even drugs — using only human sweat, the university stated in a news release.

The wearable innovation is said to be as easy as wearing an adhesive bandage.

A sweat-powered wearable has the potential to make continuous, personalized health monitoring as effortless as wearing a Band-Aid. Engineers at the University of California San Diego have developed an electronic finger wrap that monitors vital chemical levels—such as glucose, vitamins, and even drugs—present in the same fingertip sweat from which it derives its energy.

A wearable health monitor developed by Washington State University researchers can reliably measure levels of important biochemicals in sweat during physical exercise.

WSU researchers at the Engineering Teaching and Research Laboratory have developed a 3D-printed sensor capable of detecting glyphosate in beverages. 

A newly developed, low-cost sensor can detect and accurately measure the amount of the widely used and controversial herbicide, glyphosate, in droplets of liquid in a laboratory test.

Washington State University scientists have developed a method to detect the biomarkers for Alzheimer’s disease that is 10 times more sensitive than current blood testing technology.

Washington State University researchers have developed a novel way to deliver drugs and therapies into cells at the nanoscale without causing toxic effects that have stymied other such efforts.

The work could someday lead to more effective therapies and diagnostics for cancer and other illnesses.
