BAM Labs provides an FDA-approved sensor mat that is placed under mattresses to monitor a patient's presence, sleep pattern, heart rate and breathing rate. The clever part is that the patient isn't connected to any wires -- the "smart bed" does all the work. The mat can be used in a hospital or home setting. Data collected is transmitted online to an app viewable on any Internet-connected device. Doctors and caregivers can monitor multiple patients at once from the app.
