Force Sensor – Precision Force Measurement for Neuroscience and Physiology Research
The Force Sensor from Brain Products is a peripheral physiology device designed to measure changes in the force exerted by research participants during experiments. It enables researchers to capture both the timing and relative amplitude of force-related actions, providing valuable behavioral data that can be synchronized with EEG, EMG, and other physiological recordings.
Overview
Many neuroscience and human-performance experiments require precise measurement of physical interactions such as button presses, grip strength, finger tapping, or force application. Traditional response buttons often record only the occurrence of an event, whereas the Force Sensor provides continuous force measurements, allowing researchers to analyze how force changes over time.
This makes it possible to study not only when a participant responded, but also how strongly they responded.
Key Features
High-Resolution Force Measurement
The sensor measures:
- Relative force changes
- Force application timing
- Response onset and offset
- Force amplitude variations
- Continuous force profiles
Researchers can quantify subtle differences in motor behavior that are not detectable with simple event triggers.
Seamless Integration with Brain Products Systems
The Force Sensor uses Brain Products’ standard 5-pin Binder connector, allowing direct connection to a variety of data acquisition platforms.
