Keystone Electronics unveils new battery insulating pull tabs

Keystone Electronics (New Hyde Park, N.Y.) recently introduced a new line of battery insulators designed to protect batteries and circuitry from energizing during shipping and storage. Device creators can install the pull tabs in a product along with the batteries so that they can insulate and prevent the batteries from energizing prior to use. Device users simply

How Zeiss microscopes could enable battery innovation

University College London’s Electrochemical Innovation Laboratory is using Zeiss Xradia 810 Ultra X-ray microscopy to study the inner-workings of batteries and fuel cells, Zeiss recently announced. The Xradia 810 Ultra helps researchers to study the evolution of microstructure down to 50 nm resolution. Such resolution offers a 3D picture of the fine details of lithium

Morgan Advanced Materials touts new CD coating

Morgan Advanced Materials’s Technical Ceramics business announced that it is launching a charge dissipative (CD) coating for ceramic parts to support the development of compact medical equipment. Reduced size and improved resolution and imaging performance is in high demand for medical diagnostic imaging equipment like CT scanners and mobile X-ray machines. Morgan’s CD coating of

What goes into injection molding cooling time?

Part design, material selection, mold design and processing all play a role when it comes to injection molding cooling time. Jeremy Williams, RJG Here’s a value that probably sticks out in your mind if you’ve been to an RJG training event: 80%. That’s how much of the molding cycle is spent cooling the plastic part

This procedure repairs joint damage and avoids hip replacement surgery

The Ohio State Wexner Medical Center is using a new procedure to help patients avoid hip replacement surgery while still repairing their hip. The procedure, called Subchondroplasty, involves injected a bone substitute material into the hip joint. The material helps fill voids or lesions in the joint. “We want to preserve the native hip whenever

Dip molding medical device products: What you need to know

When it comes to dip molding products with emulsions of liquid rubber, it is necessary to complete a series of process steps to assure proper formation, vulcanization and finish treatment to meet the customer’s needs in the final application. Mark Agee, Kent Elastomer Products Dip molding can enable the creation of durable medical device parts in

This artificial cartilage is made using material from bulletproof vests

The same Kevlar material that is used to make bulletproof vests, jackets and gloves now has the potential to make artificial cartilage that could be implanted in the body. Kevlartilage – a material developed at the University of Michigan and Jiangnan University – can withstand just as much force as the cartilage in the human

3D printed organ models are getting way better: Here’s how

University of Minnesota researchers are taking 3D printed organ models to the next level: They look and feel like the real thing, and integrated sensors help surgeons train. There’s even the potential that such artificial models may someday become the real deal – “bionic organs” used to replace damaged biological organs. The Minnesota researchers published

PEEK formulations for new implantable devices

Since the late 1990s, polyether ether ketone has become a go-to material for companies that manufacture orthopedic implants, thanks to its radiolucency and anatomical properties. Now, custom formulations of PEEK are enabling new potential applications for the polymer. Lawrence Acquarulo, Foster Corp. Polymers have always played a role in modern implantable medical devices. But until

Biomaterials: Is there a better way for FDA to regulate them?

The medical device industry is pretty conservative when it comes to materials used in medical devices. That begs the question: Do we need a new FDA approval pathway for biomaterials? Mike Drues thinks the answer is “yes.” “It really will encourage companies to use new materials and not be hamstrung with materials that have been

Repeat sterilization for adhesives in reusable and non-disposable devices

Here’s a review of the common adhesive materials and their reaction to sterilization processes. Christine Marotta, Henkel Intricate medical devices are often constructed of thermoset and other engineered plastics, which require advanced adhesive technology. In addition to considerations of bonding, sealing, gap filling, and manufacturability, developers need to consider the sterilization plan that all materials, including

Lemo redesigns outer shell of S Series connectors

Lemo announced today that it has redesigned the outer shell of its S Series connectors with the company’s iconic “chocolate block” look. The new S Series uses the half-moon insert configuration. It’s fully compatible with the existing S Series connectors on the market since the early 1960’s. Both the straight plug and free receptacle now

6 challenges you need to overcome to create a wearable medical device

Before you start a medical wearable device project, consider the following challenges and suggestions on how to address them. Diana Eitzman and Kris Godbey, 3M Skin is unlike any other substrate. It sweats, grows hair, secretes oil, harbors bacteria, constantly sheds old cells, regenerates new ones and changes with health, environment and age – characteristics
