Why spend time maximizing efficiency in a switch mode power supply? Higher efficiency switching regulators get you more bang out of your buck. In a world of mobile devices, minimizing power consumption is a must. Don’t waste power in the power supply. This blog looks at the sources of inefficiency one would find in a […]

When I say temperature sensors, you’ll likely think thermocouples. But today I’d like to discuss NTC thermistors. Medical devices regularly need to measure temperature. Often engineers overlook or under-estimate the inherent challenges. Whether designing in thermal measurement and control capability or just temporarily instrumenting up a test rig, it’s worth thinking about how the device […]
EMC (Electromagnetic compatibility) compliance is an essential requirement for all electronic medical devices. Usually, designers partner with EMC labs (certified testing) facilities in order to assess device compliance. In this blog members of the StarFish Electrical Engineering team share tips for a productive and successful assessment during your EMC lab visit.
Recently almost every medical device I design requires a stepper motor. After working with these motors so frequently, I’d like to share what I’ve learned about medical device stepper motors, the different types of stepper motor configurations, and how to drive stepper motors properly.
An alpha device may look like it’s finished, but it’s not a medical device. A basic principle of medical device commercialization is that even though an alpha device looks like it’s finished – cool housing, looks like a device – it’s not a medical device until it passes regulatory standards and receives regulatory clearance, after […]
Navigating water ingress in medical devices can be tricky, as one of the key requirements for ISO 60601-1 is the protection against ingress. With so much development focused on the functioning of the medical device, ingress protection can be overlooked or left late in the development phase as something that is easily solvable.
Silicon photomultipliers are an exciting technology enabling applications previously only available with large, bulky PMTs to be implemented in small, low-cost, low-power form factors. If you have demanding low-light detection requirements for an upcoming project where a PMT would be too bulky, expensive, or fragile, I strongly encourage you to take a look at silicon […]
Over many years of working in optics labs, I’ve come across a variety of lab practices ranging from admirable to appalling. These practices can have a significant impact both on the quality of data and the efficiency with which it’s collected. Below, some optics lab best practices to help create an optics lab environment that […]
Improve your medical device innovation process Everyone has a mental toolkit of innovation – a series of patterns that innovative people find. They take something and they break it into pieces or they take pieces and put them together or they put things upside down or they hollow them out or they turn them inside […]
There are so many methods available to prototype that I’d like to expand upon an earlier blog. In this article I share the low-cost tips and methods on how to prototype a medical device on a budget that I use in my New Product Introduction (NPI) work. Just as importantly, I explain when I use […]
The value proposition is easy to see and the advantages can be well worth the investment. Connected medical devices are shaking up the industry. Look at just about any home healthcare device in the last few years: chances are, you’ll find some sort of wireless chipset inside to radio information to the internet for telemedicine […]
Despite a high number of university or college graduates looking for entry level work in the tech industry, companies still report difficulty in hiring . This is in part due to a medtech skills gap between entry level work and university training. Industry involvement in academia has the power to address this issue. Who better […]
