Researchers in Simon Fraser College’s Additive Manufacturing Lab are replicating a particular artform—the delicate folding of origami—to create 3D printable applied sciences to help within the combat in opposition to COVID-19, and assist medical doctors to determine and diagnose numerous well being circumstances.
Highlighting the work, led by SFU Faculty of Mechatronic Techniques Engineering’s affiliate professor Woo Soo Kim, is a low-cost, moveable 3D-printed ventilator, pushed by a patented, clever 3D-printed origami tube. An in-depth overview of the design and improvement of the innovation, not too long ago evaluated by a neighborhood staff of respiratory therapists, has been revealed within the journal Versatile and Printed Electronics.
The moveable mechanical ventilator is designed to help an individual’s respiration by reliably contracting a 3D-printed origami tube, reasonably than compressing a traditional bag-valve masks (BVM), which reduces the general dimension of the assisted respiration machine with mechanical power acquire. The 3D-printed design and light-weight supplies additionally lowers manufacturing prices.
In our moveable origami ventilator, greater than 95 per cent of elements will be 3D printable, that is why it’s actually cost-efficient. Different moveable ventilators can price over $2,000, however our 3D-printed ventilator will be produced for about $200.”

Kim says that the small and light-weight design, mixed with low manufacturing prices, makes their moveable ventilator helpful for treating COVID-19 sufferers or sufferers who want a compact and conveyable gadget outdoors of hospital settings, akin to long-term care houses or in distant rural areas and creating nations.
The staff has partnered with Vancouver-based ventilator producer Pantheon Design and Delta-based 3D-printing firm Tinkerine, with help from the Alliance program of the Pure Sciences and Engineering Analysis Council of Canada (NSERC). The staff can also be in search of additional funding and improvement companions with a aim of mass manufacturing.
Growing 3D origami-based dry electrodes for sensing robots to help healthcare professionals
Kim can also be creating and patenting 3D origami dry electrodes that can be utilized to observe affected person well being. This expertise is beneath the identical mental property technique of 3D printed origami applied sciences. The dry electrodes can detect and monitor physiological alerts, akin to heartbeat, respiration, temperature and muscle actions, all with the easy contact of the 3D origami dry electrodes.
Sooner or later, Kim envisions that this expertise could possibly be used to help medical doctors and nurses by permitting them to evaluate sufferers’ well being remotely by a robotic helper.
The humanoid robotic would additionally have the ability to monitor oxygen ranges – helpful in circumstances the place a affected person has developed extreme COVID-19. The info will be considered in real-time on the robotic’s monitor or despatched on to the healthcare supplier.
“The dry electrode does not should be geared up with the sensing robotic – it may be utilized in a hospital setting to exchange the moist gel sort electrode for electrophysiology akin to electrocardiogram or blood stress measurement functions,” Kim says. “Dry electrodes are simply one of many applied sciences beneath this portfolio of 3D origami applied sciences we’re creating right here at SFU.”
