Title: SYSTEM FOR MAGNETIC DETECTION OF MYOCARDIAL FORCES
Abstract:
Devices and techniques for magnetic detection of myocardial forces are generally described. In some examples, cardiac tissue may be cultured such that the cardiac tissue adheres to a first post and a second post. In further examples, a magnetometer may detect a change in a magnetic field resulting from a deflection of the first post in a first direction from a first position to a second position. In some other examples a signal corresponding to the change in the magnetic field may be generated. In still other examples, frequencies of the signal outside of a first frequency range may be excluded to produce a filtered signal. In various examples, the first frequency range may include frequencies associated with beating of cardiac tissue. In still further examples, a force exerted by the cardiac tissue may be determined based at least in part on the filtered signal.
