218 – BHAPI | BIOPAC Hardware API

The BIOPAC Hardware API gives software developers control over BIOPAC acquisition units. A Hardware API is available for MP160, MP150 & MP36R (Research Systems) or MP36 & MP35 (Education Systems, 4-channel units); not available for MP40,  MP41 , MP45, or MP45 (one- and two-channel units).

This application note provides an overview of the BIOPAC Hardware API (BHAPI 2.2.3). If you have specific questions or interface needs not addressed, please contact BIOPAC.

Associated Applications

• EEG: Electroencephalography - Wired and wireless EEG solutions. Record up to 32 channels of EEG and use software features for filtering, removing EOG artifacts, and complete frequency analysis.
• ERS: Evoked Response - Record evoked, late, and field potentials, as well as startle and nerve conduction. Powerful on- and off-line averaging features (P300), and dual stimulation ability with the MP150.
• Psychophysiology - Record and analyze BP, ECG, HRV, EDA, EMG, EEG, EOG, RSP, etc. Interface to stimulus presentation programs...use automated analysis routines to easily score and analyze data.
• ICG: Impedance Cardiography/Cardiac Output - Record cardiac output, thoracic impedance changes, or any kind of bioimpedance signal. Use AcqKnowledge for a fully automated ICG analysis and dZ/dt waveform classifier.
• EOG: Eye Movement - Record eye position and movement with the EOG100C amplifier. Find frequency, distance, velocity, and point of focus. Isolate behavior associated with nystagmus and saccades.
• Plethysmography - Record PPG, measure BP indirectly, look at appendage size variations, and perform sexual arousal studies using BIOPAC or 3rd-party transducers.
• Sleep Studies - Long term recordings with up to 16 channels of data. Record EEG, EOG, EMG, respiration, temp., sound, limb position and more. Filter out EEG frequencies to score sleep stages.
• Cardiovascular Hemodynamics - Hardware for human and animals. Measure continuous BP, ECG, stroke volume, cardiac output, PPG, etc. For animal and tissue look at acute and chronic dose-response.
• EGG: Electrogastrogram - Measure electrical activity of gastrointestinal system in humans and animals. Examine slow wave propagation and perform automated gastric wave analysis in AcqKnowledge.
• Noninvasive Blood Pressure Monitoring - Human - Human—continuous system with finger sensor. Fits children through large adults. MRI system also available.
• In vitro Pharmacology - Record from tissue bath, isolated organ, Ussing chamber, or use field stimulation. Advanced algorithms analyze Langendorff, working heart, and isolated perfused lung data.
• Laser Doppler Flow - Record microvascular circulation invasively or noninvasively with LDF100C. Look at the effects of drugs, exercise, inadequate blood supply, and tissue ischemia.
• MER: Micro-electrode Recording - Use micro-electrodes and MCE100C amplifier to record in-vivo or in-vitro from organisms, organs, tissues, brain slices, and cells. Record from up to 16 amplifiers simultaneously.
• Respiration | Pulmonary Function - Perform lung volume measurements, examine pressure/volume relationships, and analyze respiratory gases. Use AcqKnowledge to integrate airflow and analyze data.
• Exercise Physiology - Examine ventilation, oxygen uptake, carbon dioxide production, biopotentials, temp., and biomechanical signals simultaneously. Record wirelessly with BioNomadix, BioHarness, or TEAM Systems.
• EMG: Electromyography - Record surface, needle, and fine wire EMG—or wireless EMG with BioNomadix. Use real-time integration tools for immediate analysis or use automated EMG analysis routines.
• Biomechanics - Use BIOPAC equipment for gait analysis, goniometry, ergonomics evaluation, range of motion, EMG, Remote Monitoring or to interface with third-party equipment.
• Remote Monitoring - BioNomadix modules provide high quality, full-bandwidth data for a variety of signals—ECG, EEG, EGG, EMG, EOG, PPG, RSP, SKT, Accelerometry, Cardiac Output, Dynamometry, and Heel-Toe Strike.
• Amplifiers & Interfaces - Use BIOPAC amplifiers with MP Systems, as stand-alone devices, or with 3rd-party flow meters, force plates, sono-micrometers, telemetry equipment, metabolic carts, etc.
• Stim-Response | Virtual Reality - Synchronize events from a virtual world with physiological data from an MP150 system. Use feedback loops for greater control and automation—change the VR world in real time.
• Scripting - Customize acquisitions, display, and UI, automate analysis routines, perform batch analyses, and expedite your research time to publish faster! No experience required.
