Brand: Olimex

This is an SHIELD-EKG-EMG which allows Arduino like boards to capture Electrocardiography and Electromyography signals. The shield opens new possibilities to experiment with biofeedback. You can monitor your heartbeat and log your pulse, recognize gestures by monitoring and analyze the muscle activity as it is done in this project.

SHIELD-EKG-EMG converts the analog differential signal (the ECG/EMG biopotentials generated by muscles), attached to its CH1_IN+/CH1_IN- inputs, into a single stream of data as output. The output signal is analog and have to be discretized further with the aim to give the option of digital processing. Typically, this is done via dedicated ADC embedded in the MCU of the baseboard (like OLIMEXINO-328, OLIMEXINO-32U4, OLIMEXINO-STM32, etc). In the demo example, we have provided, “ShieldEkgEmgDemo.into”, we have used 10-bit ADC with 256Hz sampling rate.

SHIELD-EKG-EMG’s total gain is the product of the gains of each discretization stage: Instrumental Amplifier(G1=10), OAmp with regulated gain (G2=6..101) and 3rd order “Besselworth” filter (G3=3.56). Then, the Gtotal = G1*G2*G3 = 10*(6..101)*3.56. By default, we have set the G2 gain approximately ~80. Then, Gtotal = 10*(~80)*3.56 ~ 2848.
