A team of researchers at the University of Pittsburgh has developed a skin patch that can detect antibodies associated with COVID and flu infections. It's orders of magnitude more sensitive than existing tests, uses just a half volt of electricity, and can return results in 10 minutes. https://medicalxpress.com/news/2025-11-needle-flucovid-vaccines-effective.html Mon, 10 Nov 2025 14:14:02 EST news682006441 QUT researchers have created a prototype electronic device using a material made from seafood waste, paving the way for safe, flexible and sustainable wearable health sensors. https://medicalxpress.com/news/2025-09-seafood-sustainable-wearable-health-sensors.html Wed, 17 Sep 2025 07:29:04 EDT news677312941 Although lithium is highly effective in treating bipolar disorder, the chemical has a narrow therapeutic window—too high a dose can be toxic to patients, causing kidney damage, thyroid damage, or even death, while too low a dose renders the treatment ineffective. https://medicalxpress.com/news/2025-07-wearable-sensor-patients-bipolar-disorder.html Wed, 23 Jul 2025 09:37:01 EDT news672482215 In the COVID-19 pandemic era, at-home, portable tests were crucial for knowing when to wear a mask or isolate at home. Now, Penn State engineering researchers have developed a portable and wireless device to simultaneously detect SARS-CoV-2, the virus that causes COVID-19, and vitamin C, a critical nutrient that helps bolster infection resistance, by integrating commercial transistors with printed laser-induced graphene. https://medicalxpress.com/news/2025-01-biosensing-platform-simultaneously-vitamin-sars.html Tue, 21 Jan 2025 17:12:04 EST news656701921 Leveraging rapid technological advances for human health is a global trend, driving the rise of biomedical engineering research. https://medicalxpress.com/news/2024-09-team-generation-wearable-glucose-diabetes.html Wed, 18 Sep 2024 10:30:10 EDT news645874201 The fusion of man and machine is the epitome of a science fiction narrative. In real life, the first steps towards such cyborgs have long been taken: people have pacemakers to treat arrhythmias or cochlear implants to improve hearing, and retinal implants help people who are almost blind to see at least a little. https://medicalxpress.com/news/2023-11-retina-like-biochip-implants-fuse-body.html Thu, 02 Nov 2023 11:49:03 EDT news618144541 A prototype sensor that measures glucose levels in saliva could eventually offer a simple, rapid and painless way for people to monitor their diabetes, according to the KAUST researchers behind the technology. https://medicalxpress.com/news/2023-08-transistor-glucose-saliva.html Mon, 28 Aug 2023 16:14:36 EDT news612458073 Sticking an implantable sensor to the surface of a beating heart usually requires suturing around the periphery of the sensor or copious amounts of adhesive layered between the sensor and the heart. In both cases, such a sensor rarely has tight, uninterrupted contact with heart tissue, limiting the data that clinicians can collect on a patient's heart function. https://medicalxpress.com/news/2023-08-transistor-adhere-internal-tape.html Thu, 17 Aug 2023 10:40:04 EDT news611487601 Anyone familiar with antidepressants like Prozac or Wellbutrin knows that these drugs boost levels of neurotransmitters in the brain like serotonin and dopamine, which are known to play an important role in mood and behavior. https://medicalxpress.com/news/2022-12-soft-brain-probe-boon-depression.html Mon, 19 Dec 2022 13:31:04 EST news590679062 Oral cancer is the 13th most common type of cancer globally, and oral squamous cell carcinomas (OSCCs) account for more than 90% of oral cancers. An estimated 300,000 new cases and 145,000 deaths worldwide were attributed to oral cancer in 2012. https://medicalxpress.com/news/2022-12-point-of-care-biosensor-rapidly-oral-cancer.html Tue, 13 Dec 2022 11:00:02 EST news590150216 A new method for the miniaturization of biosensors will enable new possibilities for minimally invasive implants.
