Tri-axial accelerometers are high-level output transducers requiring no additional amplification since the amplifier is built into the transducer. They connect directly to the HLT100C High Level Transducer module or TEL100C module to provide three outputs, each simultaneously measuring acceleration in the X, Y, and Z direction.
5 g accelerometers are well-suited for measuring slow movements
50 g accelerometers are designed to measure quick movements
Precise acceleration measurements can be obtained with the equipment and scaling parameters detailed in this application note.
New series of unshielded 45 cm electrode leads with thin cable; suitable for facial EMG and other areas where lighter, shorter lead cables are required. Use for female Touchproof connectors to pinch clip connectors—connect electrodes to either a C-series amplifier or an MEC. The pinch connectors are light weight and the lead cable tinsel wire […]
The new issue of Psychophysiology has a study “Quantifying rapid changes in cardiovascular state with a moving ensemble average” using MEAP for preprocessing/analysis and BIOPAC hardware and software for data collection, display, and storage. The proof of concept study demonstrates a viable method for the adoption of ICG measures across the field of psychophysiology. MEAP (moving ensemble […]
BIOPAC provides software and hardware that allow for research teams to record and analyze respiration activity in physiological experimentation. Here are a few notable studies covering MRI, ECG, and Laser Doppler Flow measurement. fMRI & Thermal Perception: The neural mechanisms underlying thermal perception (how hot or cold we perceive the temperature to be) have not been fully […]
