At Purdue University researchers have come up with a way of reliably attaching thin film sensors and other small electronic devices to soft contact lenses. The capability may allow for real-time, non-invasive measurement of glucose levels, delivery of drugs directly to the eye, and maybe even tracking intraocular pressure. “We developed a ver (Read more...)

Photoacoustic Computed Tomography May Replace Mammographies for Breast Cancer Screening
Though mammography helps to provide early detection of breast cancer, it is a modality that suffers from limitations, particularly in dense breasts. A new technology, developed at Caltech, may have the potential to eclipse mammographies for spotting cancerous lesions. The photoacoustic system sends near-infrared laser light into breast tissue and d (Read more...)
Stretchable, Conductive Hydrogel as a Biomedical Sensor
Researchers at King Abdullah University of Science & Technology in Saudi Arabia have developed an electrically conductive hydrogel that can flex, stretch, and self-heal when cut and reattached. The versatile material has potential in a variety of applications including wound healing patches, wearable electronics, and touch-sensitive robotics. T (Read more...)
Health Technology Briefs from the ITF Demo Floor
Medgadget was recently invited to attend the imec Technology Forum (ITF) conference in Antwerp, Belgium. One of the highlights of the conference was the demo floor where imec, which is a non-profit R&D innovation organization, had the opportunity to show off some cool technologies from their research teams, spinoff companies, and partner organi (Read more...)
Tiny Battery-Free Implantable Devices Powered Wirelessly Using Radio Frequency Waves
Scientists at MIT have developed a wireless system that can power tiny implantable devices in the body, without the need for batteries. The system relies on radiofrequency waves emitted by an antenna outside the body, which can then power the implants from as far away as one meter and as deep as 10 cm below […]
New Way to Inject Light into Microdisk Resonators May Allow New Diagnostics
Microdisks are special tiny resonators that trap light inside themselves and enhance the incoming light for specific applications. They rely on the whispering-gallery optical effect, similar to the sound-based effect of the same name that’s demonstrated at many children’s museums. Microdisks have great potential for assessing the s (Read more...)
Pressure-Responsive Fibers Could Lead to Color-Changing Bandages
Engineers at MIT have developed photonic fibers that change color in response to pressure. The innovation could lead to color-changing bandages that allow clinicians to easily know if they’re tight enough or too tight. Compression stockings and bandages are a common treatment for venous ulcers. However, it can be difficult to tell if an optim (Read more...)

E. Coli in an Electronic Pill Can Detect Bleeding in the Stomach
Researchers at MIT have developed an ingestible chip containing genetically engineered E. coli. When swallowed, the bacteria can detect blood in the stomach, and produce light. The chip contains components that measure the amount of light produced and relays this information to a nearby smartphone, allowing a simple and non-invasive diagnosis of ga (Read more...)
Monitoring Your Health is No Sweat with Eccrine Systems’ Sweatronics Wearable
Biofluids can be a goldmine of valuable information about our health. However, most of them require sharp needles, diuretics, or sappy romance dramas (blood, urine, and tears) to produce in useful quantities. One Cincinnati area startup has developed a device that samples a biofluid that everyone produces continuously while sleeping or awake &ndash (Read more...)
Blood Test for Quick and Early Diagnosis of Pancreatic Cancer
Pancreatic cancer is notoriously famous for being a merciless killer, but the reality is that our current inability to diagnose it early is what makes it so intractable. Earlier diagnosis would allow therapies to be initiated before the cancer becomes untreatable. Researchers at University of California, San Diego may have just developed a blo (Read more...)
PeraTrend Clinical Surveillance Software Gets Clearance from FDA
PeraHealth, based in Charlotte, North Carolina, recently won FDA clearance for its PeraTrend clinical surveillance offering, which relies on smart algorithms to predict dangerous oncoming health issues, such as cardiac and pulmonary arrest, while the patient is in the hospital. The algorithms are based on the Rothman Index, a measure of how well a (Read more...)
Advanced Cancer Diagnostics Reduce Frequency of Misdiagnoses: Interview with Precipio CEO Ilan Danieli
According to 2010-2012 data from the National Cancer Institute (NCI), 40% of men and women will be diagnosed with cancer in their lifetime. In all its forms, cancer is known to be a clinically and emotionally challenging disease to manage. Despite the fact that each year 455 men and women per 100,000 patients are diagnosed […]
“Superman Vision” Gets a Boost from Vayyar’s Next Generation Chip: Interview with CEO Raviv Melamed
Earlier this month, Vayyar Imaging, a firm based in Yehud, Israel, announced the launch of its next generation CMOS System on a Chip (SOC), strengthening the company’s position as a global leader in 3D imaging technology. The new chip covers imaging and radar bands from 3 GHz to 81 GHz and, compared to many similar chips with (Read more...)

MasSpec Pen Spots Cancer on Surgical Samples
Most people undergoing a tumor excision go in knowing that the entirety of the offending tissue may not be removed successfully. Typically, tumors look just like healthy tissue and it takes quite a bit of time between when a sample is sent to the pathology lab and when the results come in. Therefore, repeat surgeries […]
Biomarker to Differentiate Between Type 1 Diabetes and Maturity Onset Diabetes of the Young
Scientists from MedGenome, Genentech and Madras Institute of Technology in India have spotted a biomarker that may help avoid misdiagnosis of Type 1 diabetes in children. Those with Maturity Onset Diabetes of the Young (MODY) have different treatment needs than Type 1 requires, but a genomic analysis like the one done by the researchers can he (Read more...)
Device Provides New Way to Visualize Brain Activity
Researchers at the Rockefeller University have developed a tiny headset that can visualize neurons in the brain turning on and off while a mouse explores its environment, or interacts with other mice. The technique could help scientists to track the interactions between brain cells and learn more about what happens in the brains of people [… (Read more...)
