Hydrogels: The Most Important New Medical Technology 02/23/2017

As a package for implantable medical devices, hydrogel material holds enormous promise. The topic is showing up with increasing regularity in the research and medical development press. In 2016, the developmental focus was on flexible electronics. That is still an important technology, and advances will continue to be made. But in 2017, the focus is […]

Value-based Health Care 02/08/2017

Value-based health care is replacing the fee for service model that the health care industry has been operating under for most of its history. Can medical device designers help in this transformation? Value-based care seeks to improve outcomes, increase patient satisfaction, and reduce the cost of care. Improving device design should have positive impact in […]

Medical Device Design for Usability 02/01/2017

Medical devices that are designed for good usability will minimize user errors. Negative outcomes are more likely to occur as a result of user error than of other device failure modes. In their paper, Evaluating and Predicting Patient Safety for Medical Devices with Integral Information Technology JaiJie Zhang and colleagues discuss using heuristic analysis as […]

Smartphone Medical Devices 01/26/2017

I’ve written several times in the past about smartphones being employed as the base platform for medical devices and diagnostic instruments. A new milestone has been reached using that strategy by researchers who have created a device that can image DNA sequences and can reportedly perform mutation analysis on living tissue. The device is portable, […]

Build Your Own Medical Wearable 01/20/2017

You can now build your very own, customized medical wearable device. A company out of Scotland, Glasgow Neuro Ltd., is offering all of the individual components you need, along with a bio-amplifier that communicates to a smartphone or tablet via Bluetooth. Dr. Bernd Porr, has been instrumental in educating the public, via a series of […]

Graphene Gyroid Geometry 01/11/2017

Researchers have been trying to get graphene to behave as a 3D material for some time. Their work might have finally paid off, but not in the way expected. Graphene is one of the strongest materials that exists. It is also light weight and has electrical properties that could give it advantages in many functional […]

Gamification Theory 01/04/2017

A recent story about Reflexion Health’s Virtual Exercise Rehabilitation Assistant (VERA) points to the continuing progress that is being made in moving medical care out of the hospital and into the home. That trend has been underway for some time, and I think it will accelerate in the years ahead. With the continuing pressure on reducing […]

Are Wearables at an Inflection Point? 12/21/2016

Wearable devices that can tell you such things as how many steps you’ve taken in a day, or what your heart rate is have become fairly common. There are many devices out there, and consumers have embraced them. But most of these devices are limited in what they can do. For many people who try […]

Thought-controlled Machines 12/15/2016

I have written in the past about how we will be able to control machines using our thoughts alone. Advances in research into our ability to do so seem to be coming more frequently. The latest is news from MedGadget, out of the University of Minnesota. A team there has been able to employ non-invasive […]

Sanitizing Robotic Surgical Instruments 11/30/2016

A recent study performed by researchers in Japan has revealed that instruments used in robotic surgery are very difficult to decontaminate. The complexity of the instruments prevents cleaning and sterilization mechanisms from reaching all areas of the instrument. The instruments are not designed to allow disassembly to clean the interior of lumens. As a result, protein […]
