Abstract: Various examples are related to bioimpedance measurements. In one example, a wearable monitoring system includes electrodes and processing circuitry configured for bioimpedance sensing. The electrodes can include a current source electrode, a current sink electrode, and voltage measurement electrodes aligned between the current source and sink electrodes. The processing circuitry can sense bioimpedance based upon excitation current applied through the current source and sink electrodes and measured voltage obtained through the voltage measurement electrodes across a range of excitation frequencies. The electrodes can be conformal and stretchable.
