New Bioink for 3D Printing and Protein Therapy

Researchers at Texas A&M University have developed a 3D-printable hydrogel bioink containing mineral nanoparticles that can deliver protein therapeutics to control cell behavior. The material does not provoke the immune system and the researchers hope that it could be useful in replacing damaged tissues for regenerative medicine. 3D printing is a promising method for creating … Continue reading

Body-Worn Electric Generator to Power Medical Implants, Wearable Devices

Many implantable and wearable devices need access to continuously available electrical power. Implants, such as cardiac pacemakers, often have to be exchanged for new ones during surgery because modern batteries have a limited lifetime. Engineers at Rice University have been working on a small and flat generator that is capable of producing significant amounts of … Continue reading

Researchers Develop Smart Bioinks to 3D Print Living Tissues

If we’re going to 3D print tissues, organs, and entire body parts, scientists will have to create advanced, highly functional bioinks. Plus, these bioinks will have to withstand being printed and must survive within the harsh interior of the body. At the Fraunhofer Institute for Interfacial Engineering and Biotechnology and University of Stuttgart in Germany, researchers … Continue reading

3M Unveils New Extended Medical Adhesive for Medical Wearables

Wearable medical devices are becoming more common, as electronics keep getting smaller, batteries are getting more powerful, and sensors more capable. The success of every wearable, and whether it will be adopted by patients, depends on whether it adheres well to the body and how little management it requires from day to day. To help … Continue reading

Triboelectric Generators to Power Implantable and Wearable Medical Devices

Wearable and implantable medical devices are constantly hungry for electricity to power their functions. Batteries, their lifetime, whether they can be recharged, and other related issues influence the design, usability, and functionality of electrically powered medical tech. Triboelectric generators that convert mechanical energy into electricity are an ideal solution, but their efficiency and other limitations … Continue reading

New Coating Keeps Intravascular Catheters Clean for Weeks

Intravascular catheters are a bane of clinical medicine, being one of the chief ways people get infected inside of hospitals. They have to be replaced routinely, putting extra strain on nurses and doctors and causing discomfort to patients. There are a ways to keep catheters relatively clean with sterile technique and specialized dressings, but there’s … Continue reading

Electric Generator Powers Cardiac Implants from Beating Heart

Cardiac implants, such as pacemakers and cardioverter defibrillators, have limited lifetimes because they’re powered by batteries that cannot be recharged. Replacement surgeries are required roughly every ten years, creating difficulties for patients, many of whom are already fragile, and incurring a huge cost on the healthcare system. Engineers at Dartmouth, working with clinicians at University … Continue reading

DowDuPont Releasing New Soft Skin Adhesive for Wearable Medical Devices

DowDuPont‘s Specialty Products Division is releasing a new soft skin adhesive, specifically designed for today’s wearable medical devices. The DOW CORNING MG 7-1020 Soft Skin Adhesive is a silicone-based product, which can be worn for extended periods of time while maintaining a tight grip and causing minimal irritation. Unlike devices that use acrylic adhesives, the … Continue reading

Implantable, Light Activated Drug Releasing Microchamber Arrays

A research collaboration between scientists in Singapore, Russia, and the UK has developed a way of building tiny microchambers that can release drugs when activated by light. The microchambers are packaged together into implantable arrays that, when illuminated by near-infrared light, will open up and let whatever is inside flow out. They’re made from a … Continue reading

Specially Designed Batteries for Wearable Devices

Researchers at the Fraunhofer Institute for Reliability and Microintegration in Germany have developed a way to pack dense batteries into flexible devices such as wristbands of wearable devices. The technology has the potential to provide the necessary power to medical wearables that will be required by next generation of power hungry multi-sensor devices. The investigators have … Continue reading
