Electronic Tattoo 03/29/2017

Well, not really a tattoo, but a sensor patch made to look like one. Flexible electronics have been in development for a number of years now, and their practical use in the medical field is beginning to be seen. This video is about a patch that monitors the body’s sweat production so you can stay […]

Hydrogels for Medical Applications – Continued 03/16/2017

Hydrogels seem to be all over the medical news these days. A recent advance that holds promise for a number of medical applications is detailed in a paper at Nature.com. Conventional hydrogels can be injected as a liquid solution. They form a gel as their polymer components crosslink. However they also absorb water, which causes […]

More on Hydrogels in Medical Device Design 03/08/2017

My last post was about how hydrogels will be an important medical technology that will see significant developments this year. Further evidence of that from another report at Medgadget. Researchers at University of California, San Diego are using 3D printing methods to build millimeter-scale networks that mimic vascular structures. From the Medgadget article: “The new method, […]

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 […]
