The soft and conformable device transmits electrocardiogram, heart rate, respiration and motion data to a remote sensor such as a smartphone. The Monitor is mounted upon a stretchable substrate with gold, skin-like electrodes together with a special circuit board in the form of a “strain-isolated soft substrate”.
The three inch long monitor is expected to shrink in size with further development and is equipped with a smallrechargeable battery that will hopefully be charged externally using a radio-frequency charging system.
The soft and conformable monitor can broadcast electrocardiogram (ECG), heart rate, respiratory rate and motion activity data as much as 15 meters to a portable recording device such as a smartphone or tablet computer.
The electronics are mounted on a stretchable substrate and connected to gold, skin-like electrodes through printed connectors that can stretch with the medical film in which they are embedded.The research was supported by the Imlay Innovation Fund at Children’s Healthcare of Atlanta, NextFlex (Flexible Hybrid Electronics Manufacturing Institute), and by a seed grant from the Institute for Electronics and Nanotechnology at Georgia Tech. The monitor has been studied on both animal models and humans.
