Ten student teams with inventions to improve people’s lives worldwide — from portable ventilators for resource-strapped hospitals, to wheelchair cushions that prevent sores, to multipurpose sleeping bags for refugees — on Saturday split awards totaling $92,500 at the annual MIT IDEAS Global Challenge showcase and awards ceremony.

Grand prize winner of $15,000 went to Umbulizer, a team developing a low-cost, portable ventilator — made by modifying and simplifying the machinery — for patients in rural areas where medical resources are scarce and unreliable.

“High-end ventilators are not affordable for hospitals in Pakistan. We’ve basically simplified the model” to make them less expensive, team member Moiz Imam, a senior in mechanical engineering, told MIT News.

An additional nine winners, chosen by a team of judges that include seasoned entrepreneurs and venture capitalists, received four $10,000 awards and five $7,500 awards.

Traditional ventilators come with about 20 different functions, which make them complex and expensive. Second-hand ventilators, which low-resource hospitals tend to buy, can run up to $15,000 to $20,000, the Umbulizer team said. The alternative is a $40 hand-operated ventilator, called an “artificial manual breathing unit,” or AMBU bag, which requires constant manual pumping.

“People end up getting those AMBU bags, which are dangerous for lungs because you cannot regulate the volume or the pressure,” team member Wasay Anwer, a junior in mechanical engineering at MIT, told MIT News. “That’s where our device comes in.”

The Umbulizer team — including Sanchay Gupta, a Harvard Medical School student, and Hamza Khan, a Harvard Business School student — is developing an automated ventilator that keeps only four critical functions, reducing the price to around $2,000. “We talked to doctors in Pakistan and they said 90 percent of the patients only need four of the core functions of traditional second-hand ventilators. Our device provides those core functions at about 10 percent of the price,” Anwer said.

The team has a working prototype and aims to pilot the device at a major Pakistan hospital in the summer. “The [IDEAS] prize money will go a long way to helping us developing the final version of that prototype,” Imam said. “It will also help us find local manufacturers, because our end goal is to mass manufacture this device.”

Throughout Saturday afternoon, 40 teams showcased innovations in the Samberg Conference Center in nine categories: water and sanitation, education and training, agriculture and food, health and medical, emergency and disaster relief, infrastructure, energy and environment, mobile devices and communication, and finance and entrepreneurship.

A team of three MIT mechanical engineers, Loop, took home a $7,500 prize for tackling an issue that is little known and affects people who use wheelchairs in developing countries: preventable pressure sores.

According to the World Health Organization, life expectancy for people with spinal cord injuries in many developing countries is as low as one year. A leading cause of death is, surprisingly, infected sores caused by sitting in wheelchair seats that cause the patient’s weight to be unevenly distributed. Sores are easily prevented with high-quality air cushions that prevent pressure concentrations. But these can cost upward of $400, which is out of reach for many people in developing countries. Lower-cost cushion options are somewhat ineffective, according to Loop.

Loop is developing a cushion made of readily available and inexpensive bicycle inner tubes that are looped through a grid of holes in a plastic base. In testing, the team said its cushion prevents pressure concentrations as well as expensive, high-quality cushions do. The team hopes that when it reaches manufacturing scale it can sell its cushions for as low as $5 each.

“The goal is that high-quality seat cushion will be available to anybody regardless of price,” team member Sarah Tress, an MIT junior in mechanical engineering, told MIT News. The other team member is Shannon McCoy, also an MIT junior in mechanical engineering. With the prize money, Loop will bring its prototype to Bali this summer to test the design and gain feedback for further refining.

The eight other winners were:

  • TravlerPack ($10,000), developing a water-resistant sleeping bag for refugees that withstands extremely cold temperatures, comes equipped with mosquito nets, and can be zipped together with other bags to fit entire families;
  • OZÉ ($10,000), developing a mobile app that empowers small business owners in Africa to make data-driven decisions;
  • DIL ($10,000), developing a mobile app that generates dictionaries and offers a convenient way to record and store proverbs, songs, and stories;
  • STEMgem ($10,000), developing tech toolkits that allow learners, especially young girls, to build internet of things and wearable technologies for sports and social interactions;
  • Aeolian ($7,500), developing an air-quality monitoring network for indoor spaces;
  • Libremente ($7,500), developing a text message-based program to improve mental health of disaster victims;
  • PreserveAir ($7,500), developing climate field storage and transport services for farmers to minimize dehydration losses; and
  • Capiche ($7,500), developing an education discussion platform that uses artificial intelligence to evaluate student learning.

This year, more than 500 interested students attended dinners and other events, many sponsored the Bose Corporation, where they learned from past IDEAS winners and entrepreneurial mentors, pitched ideas, and recruited team members. IDEAS also awarded 25 teams funding throughout the year to help them build prototypes.
