Wearable Uses Microneedles to Track Metabolism

A team of researchers at the University of California San Diego created a wearable device that uses a disposable microneedle patch to continuously sample and analyze interstitial fluid. The wearable can measure glucose, alcohol, and lactate levels, all of which could be useful information for patients with diabetes. The disposable patch is attached (Read more...)

Wearable Sweat Sensor Warns of Impending Cytokine Storm

Researchers at the University of Texas at Dallas, in collaboration with a company called EnLiSense, developed a wearable electrochemical sweat sensor that can detect chemokines in sweat, alerting the wearer and clinicians to a viral or bacterial infection. The device also warns of an impending cytokine storm, where high levels of inflammatory molec (Read more...)

Smartphone App to Diagnose Neurological Disorders

A team at the University of California San Diego has developed a smartphone app that can precisely measure changes in pupil size as a potential method to assess a variety of neurological conditions and disorders, including Alzheimer’s disease and ADHD. The technique relies on the near-infrared cameras that newer smartphones use for facial rec (Read more...)

Multiplex Immunoassay for Dengue Diagnosis

Researchers at the University of Reading in the UK created a rapid multiplex immunoassay for the detection of Dengue fever. The technology, which the researchers call the Cygnus system, aims to provide improved sensitivity compared with lateral flow tests and improved convenience and speed compared with conventional lab tests. As a point-of-care de (Read more...)

Multi-Purpose Sensor for Rapid, Accurate COVID-19 Testing

Researchers at Johns Hopkins University developed a COVID-19 testing technology that is based on surface enhanced Raman spectroscopy (SERS) coupled with machine learning. The technique does not require sample preparation or special training and can deliver results in as little as 25 minutes, with an accuracy that is comparable to that of PCR, the c (Read more...)

Magnetic Tentacle Robot Travels Deep into Lungs

Researchers at the University of Leeds in the UK have created a magnetic “tentacle robot” that is just 2 mm in diameter, which they hope will be able to navigate through some of the smallest airways in our lungs. At present, a bronchoscope is used to investigate the lungs, but this cannot pass into very […]

Optical Probe Measures Dental Plaque Acidity

A team at the University of Washington have developed an optical probe that can detect the acidity of dental plaque. The acidity created by bacteria within plaque causes cavities, and knowing which areas of the teeth are particularly acidic could help dentists to predict where cavities are likely to arise. The knowledge could help someone [… (Read more...)

Blood Clotting Test on a Smartphone

Researchers at the University of Washington have developed smartphone-based technology that can allow someone to perform a blood clotting test at home. The technology is low-cost and easy to use. The test involves placing a drop of blood into a plastic attachment that can be viewed by a smartphone camera. The smartphone then vibrates the […]

Quick and Accurate COVID Test Uses LAMP Assay

Researchers at the University of Washington developed a new COVID testing technology that can provide accurate results in as little as 30 minutes. The technology intends to be a bridge between PCR tests, which are accurate but slow, and antigen tests, which are rapid but suffer from reduced accuracy. The system provides results straight to [&hellip (Read more...)

Cheap and Portable COVID-19 Test Lab

Researchers at Queen Mary University of London have created a low-cost, portable COVID testing kit intended for use in remote, low-resource regions of the world. They describe the approach as a lab-in-a-backpack, and it makes use of a recycled computer hard-drive as a centrifuge. The test assay relies on loop mediated isothermal amplification (LAMP (Read more...)

Quantum Sensor to Detect SARS-CoV-2 More Accurately

Researchers at MIT have designed a quantum sensor to detect SARS-CoV-2. While the device is still theoretical, the researchers have used mathematical simulations to show its potential, and the data and design indicate that it may be faster, more accurate, and less expensive than the current gold-standard technique, PCR. The system is based on nanod (Read more...)

New Wearable Detects Respiratory Exacerbations: Interview with Dr. Maria Artunduaga, CEO of Respira Labs

Respira Labs, a medtech company based in California, created the Sylvee sensor, an adhesive patch that the user wears on their lower rib cage, and which monitors respiratory health. The device works through acoustic resonance, whereby it emits sound into the chest cavity and analyzes the echoed vibrations. The measured data provide information on l (Read more...)

Washable Fabric Measures Electrical Activity of Muscles

Researchers at the University of Utah engineered a wearable fabric that can function as a biosensor, measuring electrical activity of muscles. The technology could be useful for physical rehabilitation, allowing clinicians and physical therapists to monitor patients’ progress. The fabric contains a network of silver flakes and gold nanopartic (Read more...)

Multistep Lateral Flow Devices Perform Advanced Assays

Researchers at Georgia Tech have developed a lateral flow test platform that can perform advanced assays that would otherwise require a laboratory. By controlling the flow of liquid through the lateral flow test, the research team designed it so that it can perform advanced multistep assays that do not require sophisticated lab equipment and signif (Read more...)
