12 problemsA few problems to explore
12 totalImplantable bioartificial kidney
A compact implanted device could combine blood filtration with living kidney cells. Can it provide enough continuous function to replace dialysis safely for long periods?
Neural-implant lifetime testing
Can short laboratory tests predict how implanted brain electrodes will fail over years?
Noninvasive continuous glucose monitoring
Can a skin-worn sensor track glucose reliably over everyday life without repeated invasive calibration?
Small-diameter vascular grafts
Can a readily available artificial small artery remain open and remodel safely for long-term human use?
Deep-tissue sound printing
Sound can form injected materials inside tissue. How can a printer keep its pattern in the right place as deep tissue moves?
Wearable cardiac ultrasound
Wearable ultrasound can track deep tissues. How can heart measurements stay calibrated when a flexible array bends and its contact changes?
