Abstract
This disclosure describes devices, system, and a method for the prediction and prevention of acute decompensated heart failure or other patient conditions involving fluid accumulation in legs or hands. In one example, a wearable device contains a drift-free leg-size sensor and a tissue-elasticity sensor. Both sensors may be relatively inexpensive and developed using innovative new sensing ideas. Preliminary tests with the sensor prototypes show promising results: the leg-size sensor is capable of measuring 1 mm changes in leg diameter and the tissue-elasticity sensor can detect 0.15 MPa differences in elasticity. In another example, a wearable system includes sensors for measuring a variety of physiological parameters, a processing module, and a communication module. A low-profile instrumented sock, e.g., a wearable device, with multiple sensors can provide an indication of heart failure status for a patient.
