FEMG Smart Amplifier

The fEMG Electromyography Smart Amplifier is designed specifically for recording facial EMG signals and electrical activity from other small muscle groups. Use with AcqKnowledge™ software to analyze facial expressions and startle paradigms.

BIOPAC’s new Smart Amplifiers are designed for great data. Smart Amplifiers improve performance by amplifying the physiological signal close to the subject, which allows a high-level voltage connection to the data acquisition system and reduces noise artifact.

AcqKnowledge Smart Amp setup includes guides and prompts to prevent errors. Setup includes an option to toggle Comb Filter on or off. Plus, channels are automatically set to be plotted and included in input values display, with the initial visual range set to the min/max input range for that Smart Amplifier signal type, in appropriate units.

Connect short-cable leads from the proven BN Series of accessories—BN-EL*-LEAD3 electrode lead if a ground electrode is required or a BN-EL*-LEAD2 electrode lead if there is already another Smart Amplifier with a ground lead on the subject—and use with disposable EL500 Series electrodes.

The Smart Amplifier may be attached to the subject either using the included Velcro backed clip or optional Velcro straps around the subject. The amplifier terminates with a 3 m long cable and connects to the AMI100D Amplifier Input Module.
