Abstract
Modular, miniaturized cardiovascular sensors, systems, methods, and wearable devices for the non-obtrusive evaluation, monitoring, and high-fidelity mapping of cardiac mechanical and electromechanical forces and central arterial blood pressure are presented herein. The sensor manufacturing process is also presented. Using accelerometers, the sensors register body-surface (preferably torso-surface) movements and vibrations generated by cardiac forces. The sensors may contain single-use or reusable components, which may be exchanged to fit different body sizes, shapes, and anatomical locations; they may be incorporated into clothing, bands, straps, and other wearable arrangements. The invention presents a practical, noninvasive solution for electromechanical mapping of the heart, which is useful for a wide range of healthcare applications, including the remote monitoring of heart failure status and the guidance of cardiac resynchronization therapy. Exercise and cardiovascular fitness tracking applications are also presented.
