A cardiac event monitor is a medical diagnostic device like a long term ECG, which is monitoring abnormal heart activity. The results get saved automatically and if the patient presses a button. The long recording time of 14 days is important to make a clear diagnosis from rare symptoms like arrhythmia or heart diseases. The information get recalled by a doctor via RFID technology. The small patch is working with a printed battery while the bigger one is powered by printed electro active polymer, which generates power with the breathing and the expansion of the chest.
A printed cardiac event monitor frees the patient from the console and the cables, which belong normally to an event monitor, because it sticks on the skin like a patch. Made through an industrial printing processes the patch is a lot cheaper than normal portable ECGs and so it can be used more often to make heart diagnostics.
