Integrated programmable wearable device for hemodynamic monitoring

A system for monitoring hemodynamic signals of a user, the system comprising:

• a wearable device configured to be worn on a limb of the user, the wearable device comprising:
• an electrode array comprising one or more current generation electrodes and one or more voltage detection electrodes;
• one or more electrocardiogram (ECG) electrodes configured to acquire biopotential signals of the user;
• an optical sensing subsystem comprising a light-emitting device configured to emit light toward skin tissue of the user and one or more photodiodes configured to detect light reflected from and/or transmitted through the skin tissue;
• an accelerometer configured to detect motion of the user;
• a processor;
• and
• a memory, including instructions, stored thereon, when executed by the processor, cause the wearable device to:
• generate a photoplethysmography (PPG) signal based on signals detected by the one or more photodiodes;
• acquire an ECG signal using the one or more ECG electrodes and an electrical bioimpedance (EBI) signal using the electrode array;
• and
• process the ECG signal, the PPG signal, and the EBI signal based at least in part on motion detected by the accelerometer to compensate for motion-related effects and generate one or more updated physiological signals.
