Microscopic Graphene Flakes to Stop Epileptic Seizures

During epileptic seizures, the brain’s excitatory neurons go haywire, generating extreme amounts of electric activity. There are already electronic devices available that help to prevent and mitigate seizures, but so far they’re only effective in some patients while having all the downsides of a serious implantation. A team of European researchers from Sissa (International School … Continue reading

Optical Fibers for 3D Tissue Imaging Inside Body

Researchers at RMIT University in Australia have developed a technique to allow an optical fiber probe to obtain 3D images of tissues deep within the body. The technology could pave the way for minimally invasive 3D optical biopsies. An optical biopsy allows clinicians to view tissues in real-time within their native environment, and avoids the … Continue reading

Kevlar with Conductive Nanowires Makes for Perfect Heat Pads

Electric heating pads are very popular for relieving minor aches and pains. They’re fairly cheap and are easy to use, but the heat distribution is uneven and the pads themselves tend to be lumpy or downright rigid. Wearing them while walking around is impractical, as they don’t wrap well around joints and tend to be … Continue reading

Nanoparticles and Microneedles for Painless Vaccinations

At Leiden University in The Netherlands, research is being done on making vaccinations easier and more effective. Currently, needles are commonly used and no one, particularly children, is happy about that. Microneedles patches have been developed in the past, but while they’re effective in some applications, they suffer from many limitations. At Leiden University one … Continue reading

Smart Textiles to Release Drugs When and Where Needed

At the Swiss Federal Laboratories for Materials Science and Technology (Empa) researchers are working on integrating therapeutic drugs into textiles that can release them into the skin as needed. The researchers envision pain medication to be administered as soon as the body severely during a sports injury, or an antibiotic can be released as soon as … Continue reading

Graphene Spike Coating for Implants Kills Any Bacteria Trying to Settle

Graphene, the material that consists of a one atom thick layer of carbons, is so impressive that its development was awarded a Nobel Prize in physics. To add to its abilities, researchers at Chalmers University of Technology in Sweden used it to create microscopic spikes that kill bacteria upon contact. Because our native cells are … Continue reading

Hair-Sized Fiber-Optic Probe Can Measure Temperatures Deep Inside the Body

Researchers at the University of Adelaide have developed a tiny fiber-optic probe that can measure temperatures deep inside the body, while imaging structures in the region of interest. The probe, which has a similar thickness to a human hair, could help researchers to investigate the effects of drugs that raise temperatures in specific parts of … Continue reading

On-Skin Flexible Screen for Displaying Live Health Information

Scientists at the University of Tokyo have developed an elastic display that can be affixed to the skin to display the waveform of an electrocardiogram, or other health parameters, detected by a skin sensor. When combined with a communication module, the system can transmit the data to a smartphone and the cloud, allowing doctors to … Continue reading

Skin Patch Controls Blood Sugar Without Finger Pricks or Injections

Researchers at National Institutes of Health’s National Institute of Biomedical Imaging and Bioengineering (NIBIB) have developed a special patch for Type 2 diabetics that helps to control glucose levels in a novel way. The technology, once fully proven out and optimized, may work for days or even weeks at a time. The patch is made of … Continue reading

Abderma, a High Absorbency and Retention Material for Wound Applications

On our visit to Med in Ireland medtech industry event, we had a chance to check out some cool indigenous materials engineering that goes on in Ireland to benefit medtech. Specifically, ATD emolda, a company based outside of Dublin, was showing off its Abderma foam, a product designed for wound management applications. Abderma, a biocompatible … Continue reading
