Biopotential Sensors

Biopotential sensors detect small electrical signals generated within the body, for example by the heart. The biopotential signals are typically conditioned and sent to a microprocessor for storage, calculation, or display by a health monitoring device. Biopotential measurements are used for fitness monitoring or by healthcare professionals to determine the overall health of a patient under observation. Examples of cardiac parameters, which can be recorded using this technique include electrocardiogram (ECG or EKG) and R-R intervals.

Our biopotential sensors are complete biopotential and bioimpedance (BioZ) analog front-end (AFE) solutions for health monitoring applications. They offer clinical grade accuracy and ultra-low power operation to enable high performance and long battery life for clinical and fitness applications. Our biopotential sensors provide electrocardiogram (ECG) waveforms, heart rate and pacemaker edge detection, and bioimpedance measurements for calculating respiration. They are available in small wafer-level packages (WLPs) to support wearable applications such as body patches, wrist-worn devices, and chest straps.
