In a time of COVID-19 restrictions and minimal travel, many people are turning to virtual doctor appointments and consultations as a safer alternative to in-person doctor visits. Researchers at Missouri S&T are working to make this new wave of telemedicine more successful by creating an oxygen-sensing patch printed on a flexible, disposable bandage that can interact with a smartphone. This smart bandage could enable remote monitoring for the early detection of illnesses such as pressure ulcers, allowing for immediate treatment or intervention.
