We’re four high school sophomores developing Turnwise to help nursing teams use pressure data when caring for patients with limited mobility. Our focus is a discreet mat that fits beneath a normal fitted sheet and helps caregivers respond to pressure, movement, and moisture.

Turnwise started with something Mateo saw firsthand. In the late stages of his grandmother’s life, she developed pressure ulcers, and he saw how painful they were and how much depended on her being repositioned in time. It stuck with him that an injury this serious is so often preventable.
Tommy grew up hearing about pressure injuries from his parents, who are both doctors. Their stories showed us how often these injuries happen, and they taught us what a real solution has to handle in a hospital or nursing home: it has to be easy to clean, thin enough that patients never feel it, and safe if a patient ever needs to be defibrillated. That is why every part of Turnwise is sealed inside an insulating cover with no exposed metal.
When the four of us teamed up for the Conrad Challenge, we wanted to build something that could help families and care teams facing the same thing. Turnwise is our answer: a thin pad that shows caregivers where pressure is building, so they can act before it becomes an injury.
Give caregivers a clearer picture of pressure, movement, and moisture throughout a patient’s time in bed.
Patient comfort, clear information for caregivers, and a design that can be cleaned, repaired, and maintained.
