Highschool scholar Archishma Marrapu has made important strides within the area of biomedical engineering. Her want to make use of her technical abilities to assist others led her to develop low-cost improvements together with an automatic pill-tracking system that reminds sufferers to take their drugs. Her Mission Tablet Tracker has caught the eye of main pharmaceutical corporations together with CVS, a big U.S. pharmacy chain.
Marrapu, a scholar on the Thomas Jefferson Excessive College for Science and Expertise, in Alexandria, Va., got here up with the thought final summer season after seeing her grandfather battle to recollect to take life-saving drugs at particular instances every day. She got down to create a tool that might assist him and thousands and thousands of different folks handle their drugs successfully. Her 3D-printed prescription bottles are outfitted with ultrasonic sensors, which preserve observe of the capsules disbursed. The accompanying cell app is programmed with a number of options together with AI sample evaluation to detect skipped doses and misuse, in addition to ChatGPT to offer data to customers, resembling methods to mitigate negative effects.
By switching to Marrapu’s tracker from conventional prescription bottles, pharmacies may enhance treatment adherence, stopping intensified medical situations and decreasing the variety of deaths—presently about 125,000 yearly—because of forgetting to take a prescribed drug or misusing it, based on the World Well being Group.
Marrapu offered a poster on her invention at this 12 months’s IEEE Built-in STEM Schooling Convention at Johns Hopkins College’s Utilized Physics Laboratory, in Laurel, Md. She acquired the IEEE Technical Excellence Award.
“I wish to be a changemaker in society and make a significant distinction in folks’s lives,” she says. “I firmly consider that by combining the ability of well being care and expertise, we are able to tackle among the most urgent challenges confronted by people and communities worldwide.”
Disrupting the high-priced biomedical system market
Earlier than creating her automated pill-tracking software, Marrapu carried out market analysis. She discovered that comparable units had been costly, some charging a excessive month-to-month subscription plan of just about US $100—which places them out of attain for many individuals.
“I got down to create one thing everybody may use no matter socioeconomic background,” she says. “Well being care has so many challenges that may be solved utilizing easy, cheap expertise. Why can’t we make biomedical units which are each inexpensive and useful?”
Related instruments additionally don’t account for human errors resembling forgetting to take a capsule on time or ingesting too many.
After a number of iterations, Marrapu landed on a design much like the prescription bottle pharmacies use at this time, solely built-in with AI and different elements that she constructed and programmed herself.
That features LEDs that mild up when it’s time to take a capsule, as properly a buzzer.
Her prescription bottles can be bought on to pharmacies, she determined.
Marrapu developed an app to accompany the system. It permits the consumer to scan the bar code on the prescription bottle, which then autofills utilization details about the prescription, together with what number of capsules are to be taken and the way usually. When it’s time to take the treatment, not solely will the bottle mild up and buzz; customers are also notified on their cellphone.
“Everybody has a spot in STEM, and one of the best ways to steer is by instance.”
By incorporating these 3 ways for the affected person to be reminded, the system can alert those that are hearing-impaired or visually impaired as properly.
To take the treatment, the consumer pushes a button on the bottle lid; the prescribed capsules are disbursed from a gap on the backside. The lid is for design functions solely, to duplicate the feel and appear of atypical prescription bottles.
The variety of capsules taken and the time of dosage is then recorded on the app. If the treatment will not be disbursed on the scheduled time after repeat reminders, the app routinely notifies the designated medical skilled or caretaker.
The app additionally lists sure meals the affected person ought to keep away from, relying on the treatment. Grapefruit, kale, cured meats, and different meals can have an effect on the way in which some medicines work within the physique.
One other app function lets customers give the explanation why they’ve stopped taking a specific treatment, resembling negative effects or monetary points. The app can present suggestions resembling methods to treatment the negative effects, or it may counsel a generic various. It additionally notifies the medical skilled or caretaker.
The pill-tracking system has a pattern-analysis algorithm that goals to assist forestall prescription drug misuse. The algorithm tracks what number of capsules had been disbursed “on demand” by the consumer. It may be achieved when, for instance, the affected person drops a capsule on the ground and must dispense one other to exchange it. The sample evaluation identifies when somebody is taking extra treatment than the physician prescribed and notifies the physician or a caretaker.
Getting in Entrance of the Buyer
Marrapu first pitched her system to CVS executives in February. She additionally visited pharmacies in her space to interview pharmacists and prospects.
“This helped the evolution of my product,” Marrapu says. “There was suggestions, for instance, from these with arthritis, or aged individuals who had a tough time urgent the button. Assembly with pharmacists, I bought the thought to include contact ID and voice recognition within the subsequent iteration to make it less complicated to dispense treatment.”
Executives at CVS’ Digital Innovation Lab stated they had been impressed by Marrapu’s system. Collectively they’re partnering on subsequent steps to make sure the following model is extra handy and inclusive.
A few of Marrapu’s longer-term plans are to launch a startup to deliver the product to market and to develop extra inexpensive biomedical units.
It’s by no means too early to start out a STEM profession
Marrapu grew up in a household and neighborhood the place lots of the adults labored in technical fields. Her mother and father each have jobs in data expertise.
She started competing in science, expertise, engineering, and math competitions at age 4. She participated within the First Lego League, a global robotics competitors for youngsters in grades 1 via 8. She went on to enter American Laptop Science League competitions for college students in grades 1 via 12.
Marrapu participated in ACSL nationwide competitions, profitable a lot of them. She realized to code within the fourth and fifth grades, she says, turning into Java– and Python-certified.
It was throughout a visit to India visiting household whereas within the seventh grade that she discovered her ardour for biomedical engineering. At a charitable belief run by a household good friend, Marrapu witnessed sufferers who had been receiving prosthetic limbs for gratis. The good friend confirmed her the factitious limbs, and Marrapu observed they didn’t have performance.
When Marrapu returned to highschool that 12 months, she constructed her first biomedical system: an AI-powered prosthetic hand. Comprised of cheap electronics and 3D-printed elements, it provided the consumer a spread of movement and gripping capabilities. She then donated some to the belief.
She launched a nonprofit, STEMifyGirls, that very same 12 months to empower younger ladies to enter STEM fields. The group presents hands-on actions, competitions, and assets to assist college students turn into occupied with STEM fields and purchase new abilities.
“I’ve at all times had a whole lot of assist from my household and neighborhood to pursue no matter pursuits me, however I do know that not everybody has the identical assets that I had,” she says. “I wished to offer younger ladies with the identical alternatives.”
By partnerships with organizations together with the Maryland STEM Competition, the Washington Academy of Sciences, and the Cyber & Steam World Innovation Alliance, STEMify has reached some 4 million college students, she says.
Fingers-on studying prepares college students for the actual world extra successfully than textbooks or classroom studying, Marrapu says, and he or she needs to offer that have to as many ladies and younger ladies as she will.
“Everybody has a spot in STEM,” Marrapu says. “And one of the best ways to steer is by instance.”
