  • Patent number: 11331027
    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.

  • Publication number: 20160061814
    Abstract: The present technology relates generally to microfluidic devices for measuring platelet coagulation, and associated systems and methods. In some embodiments, a fluidics device includes an array of microstructures including pairs of generally rigid blocks and generally flexible posts. The fluidics device further includes at least one fluid channel configured to accept the array. The fluid channel is configured to induce fluid flow of a biological sample, such as whole blood, through the array. The fluidics device can further include a detection component configured to measure a degree of deflection of one or more of the flexible posts in the array. In some embodiments, the fluidics device comprises a handheld device and usable for point of care testing of platelet forces and coagulation.
