An backward accessory developed by engineers at the University of British Columbia (UBC) could pave the way for ultrasounds scanners that amount as little as $100. Barely bigger than a acclaim card, the UBC ultrasound sensor is mobile, wearable, and can be powered by a smartphone.
Ultrasound machines about use piezoelectric crystals to actualize those first photos of a person’s life. In contrast, the technology alien by the UBC aggregation uses tiny cavernous drums, which are cheaper to fabricate.
“We replaced the piezoelectric technology acclimated in bartering ultrasound machines for drum-like sensors alleged CMUTs,” Carlos Gerardo, a UBC Ph.D. applicant who formed on the project, told Digital Trends. “These CMUTs action abounding abstruse advantages over the piezoelectric technology, but their boundless use is bedfast by aerial artifact costs. We on the added side, absitively to use bargain plastic-like polymer abstracts to actualize the aforementioned affectionate of drums structures alleged polyCMUTs. It turns out that by application polymers, we were able to actualize high-performance ultrasound [sensors] for a few dollars only.”
Besides lower costs, one of the better advantages of the UBC accessory is that is doesn’t crave abundant activity to operate. A smartphone can do the trick. That agency the accessory could be acclimated in alien areas and regions after reliable admission to electricity. And the accessory doesn’t skimp on affection either. According to the researchers, the UBC accessory produced sonogram images on par with accepted ultrasound sensors.
“The affection of the created images is commensurable in affection to the ones acquired by bartering ultrasound machines, except that in our case we did not accept to use a circuitous and big-ticket cyberbanking interface to actualize the images,” Gerardo said. “Moreover, we did this application abundant lower voltage levels than the ones begin in bartering devices. This translates anon into an continued assurance for patients.”
Since the accessory is baby and portable, Gerardo and his aggregation anticipate it actuality activated anon to a patient’s skin, area it could adviser basic signs. They are currently creating prototypes for medical uses.
