GENERAL DESCRIPTION
Our low-noise ECG local differential triode
configuration enables fast application andunobtrusive single-lead ECG data acquisition(althoughcustom
electrodecable
configurations are available). The state-ofthe-art design of the analog frontend on thissensor is specifically targeted at analyzing
minutiae in the data and provides medicalgrade raw sensor data.
This sensor can be used to extract heart rate
data and other ECG features, enabling its
application in research fields such as
biomedical, biofeedback, psychophysiology,and sports, among many others.

Note: This sensor is also available with the electrodes cables (A2 & A3) in 30cm lengths.
1 The number of bits for each channel depends on the resolution of the Analog-to-Digital

Converter (ADC); in biosignalsplux the default is 16-bit resolution (𝑛 = 16), although 12-bit(𝑛 = 12) and 8-bit (𝑛 = 8) may also be found on older devices.
