Could a DIY Ultrasound be in Your Future?
September 12, 2018 | University of British ColumbiaEstimated reading time: 1 minute
Engineers at the University of British Columbia have developed a new ultrasound transducer, or probe, that could dramatically lower the cost of ultrasound scanners to as little as $100. Their patent-pending innovation—no bigger than a Band-Aid—is portable, wearable and can be powered by a smartphone.
Conventional ultrasound scanners use piezoelectric crystals to create images of the inside of the body and send them to a computer to create sonograms. Researchers replaced the piezoelectric crystals with tiny vibrating drums made of polymer resin, called polyCMUTs (polymer capacitive micro-machined ultrasound transducers), which are cheaper to manufacture.
“Transducer drums have typically been made out of rigid silicon materials that require costly, environment-controlled manufacturing processes, and this has hampered their use in ultrasound,” said study lead author Carlos Gerardo, a PhD candidate in electrical and computer engineering at UBC. “By using polymer resin, we were able to produce polyCMUTs in fewer fabrication steps, using a minimum amount of equipment, resulting in significant cost savings.”
Sonograms produced by the UBC device were as sharp as or even more detailed than traditional sonograms produced by piezoelectric transducers, said co-author Edmond Cretu, professor of electrical and computer engineering.
“Since our transducer needs just 10 volts to operate, it can be powered by a smartphone, making it suitable for use in remote or low-power locations,” he added. “And unlike rigid ultrasound probes, our transducer has the potential to be built into a flexible material that can be wrapped around the body for easier scanning and more detailed views–without dramatically increasing costs.”
Co-author Robert Rohling, also a professor of electrical and computer engineering, said the next step in the research is to develop a wide range of prototypes and eventually test their device in clinical applications.
“You could miniaturize these transducers and use them to look inside your arteries and veins. You could stick them on your chest and do live continuous monitoring of your heart in your daily life. It opens up so many different possibilities,” said Rohling.

It’s Only Common Sense: Storytelling That Sells—Stop Pitching, Start Painting Pictures
09/15/2025 | Dan Beaulieu -- Column: It's Only Common SenseLet me tell you something that most salespeople — even the ones flashing Rolexes and bragging about crushing their quotas—still haven’t figured out: Facts don’t close deals, stories do. People file away facts while they feel stories. Facts tickle the brain, but stories punch the heart, and it’s the heart that signs the check every time.
Elementary Mr. Watson: Running the Signal Gauntlet
09/11/2025 | John Watson -- Column: Elementary, Mr. WatsonIf you’ve ever run a military obstacle course, you know it’s less “fun fitness challenge” and more “how can we inflict as much pain in the shortest time possible?” You start fresh—chest out, lungs full of confidence, thinking you might even look good doing this—and 10 seconds later, you’re questioning all your life choices.
It's Only Common Sense: Leveraging AI in Your Sales Strategy
09/01/2025 | Dan Beaulieu -- Column: It's Only Common SenseLet’s get one thing straight: AI isn’t here to replace you; it’s here to make you smarter and faster. Every time a new tool shows up, half the sales floor panics: “They’re going to automate us out of a job!” This is shouted while doomscrolling LinkedIn. Relax. Sales is still, and will always be, about human connection, trust, and delivering value. However, if you’re not using AI to your advantage, you’re handing your competitors a loaded gun and asking them to shoot first.
Global Sourcing Spotlight: How to Evaluate Supplier Capabilities Worldwide
08/20/2025 | Bob Duke -- Column: Global Sourcing SpotlightIn global sourcing, the difference between a competitive edge and a catastrophic disruption often comes down to how well you vet your suppliers. Sourcing advanced PCBs, precision components, or materials for complex assemblies demands diligence, skepticism, and more than a little time on airplanes. Here’s how to do your due diligence when evaluating international suppliers and why cutting corners can cost you more than money.
It’s Only Common Sense: Why Failure Is an Opportunity for Growth
08/18/2025 | Dan Beaulieu -- Column: It's Only Common SenseIt’s only common sense that failure, as painful as it may be, is one of the best teachers. Whether you’re running a business, managing a team, or navigating your personal journey, failure offers an unparalleled opportunity to learn, grow, and emerge stronger. If you’re not failing now and then, you’re likely not trying hard enough or pushing yourself out of your comfort zone. Here’s why failure is not just inevitable but also invaluable, and how to use it as a steppingstone to success.
