Instruments for biomechanics and movement analysis
In biomechanics research, BIOPAC can record muscle activity, force, pressure, acceleration, joint angles and contact events. These measurements link physiological activity with movement phases or task performance. Scope depends on the amplifiers, transducers, mounting and acquisition settings.
EMG describes electrical activity in selected muscles; goniometers and accelerometers capture selected movement variables; force and pressure transducers measure interaction with the environment. These are not automatically a complete 3D kinematics system. Projects that require full segment tracking may need an external platform and verified synchronisation.
Movement tasks require attention to participant freedom, cable routing or wireless modules, secure sensor mounting and a shared timeline for all channels.
Biometric measurement and signal-recording systems
“Biometrics” in this category means physiological measurement rather than identity recognition. Depending on configuration, a system can record cardiac, muscular, electrodermal, respiratory, pulse, temperature and movement signals.
ECG and PPG
Different views of cardiac activity and pulse wave, requiring appropriate sensors, sites and artifact control.
EDA and respiration
Common psychophysiological signals whose interpretation depends on the protocol and comparison between conditions.
EMG and movement
Muscle activity can be synchronised with force, angle, acceleration and task events.
Every signal path includes the acquisition unit, an amplifier or receiver, sensor, leads, electrodes or mounting hardware and software settings.
BIOPAC systems for data acquisition and analysis
Modular BIOPAC platforms support configurations from a few channels to complex multisignal studies. Start with the data-acquisition units, then add the required amplifiers, sensors and software.
A protocol may use GSR and EDA sensors, PPG and SpO2 sensors, ECG equipment and EMG equipment. AcqKnowledge supports acquisition setup, display, event marking and analysis within the capabilities of the selected version and licences.
BioNomadix provides wireless recording for selected signals, subject to transmitter and receiver compatibility, channel count, range and battery life.
How to select instruments for a biomechanics laboratory
Begin with a signal table. For every channel define the quantity, range, sampling rate, sensor, mounting and synchronisation. Then select a wired or wireless platform and a complete accessory list.
- Signals and channels: each modality needs the correct amplifier or receiver.
- Participant movement: affects cables, wireless transmitters and mounting.
- Synchronisation: define markers, direction, latency and export format.
- Consumables: include electrodes, gels, tapes, leads and hygiene items in the BOM.
- Software: version, licences and analysis must match the protocol.
For structural strain or temperature measurement, compare fibre-optic sensors. Optical-path equipment is listed under photonics laboratory equipment.
These are research instruments. They must not be treated as medical diagnostic equipment unless the manufacturer has explicitly assigned that intended use to the specific product.
Send the signal list and study conditions
Include channels, participant mobility, session length, sensors and devices to synchronise.
