Tri-axial accelerometers are high-level output transducers requiring no additional amplification since the amplifier is built into the transducer. They provide three outputs, each simultaneously measuring acceleration in the X, Y, and Z direction. They connect directly to the AMI100D Amplifier Module Interface—released in 2019—and the older HLT100C High-Level Transducer module or TEL100C module; check connection compatibility by specific part number, including suffix.
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.
Electrodermal Activity (EDA) is an objective index for understanding emotional states. Researchers measure EDA to gain insights on psychological or physiological response, leading them down the path of scientific discovery. Because EDA is so important to research, BIOPAC has created tools to optimize event-related EDA analysis. Topics include: how to identify skin conductance responses, convert stim events from E-Prime SuperLab, Presentation, Vizard, etc., into AcqKnowledge events that can used for analysis, and score skin conductance responses using the AcqKnowledge automated EDA analysis tool.
NIRS and CNAP—Pairing great tools for great data Cerebral hemoglobin concentration (blood mass in the brain) is frequently measured in the prefrontal cortex, and systemic arterial blood pressure is known to be a variable factor based on the hemoglobin concentration. A leg pressure cuff was used to constrict and release blood flow to create a […]
BIOPAC’s just released Introductory ECG Guide addresses fundamental to advanced concerns to optimize electrocardiography data recording and analysis. Topics include: ECG Complex; Electrical and Mechanical Sequence of a Heartbeat; Systole and Diastole; Configurations for Lead I, Lead II, Lead III, 6-lead ECG, 12-lead ECG, precordial leads; Ventricular Late Potentials (VLPs); ECG Measurement Tools; Automated Analysis Routines […]
