Background:

Accurate measurement of maximal voluntary bite force is crucial for diagnosing and monitoring various medical conditions.
Existing bite force sensors can be expensive, complex to fabricate, or lack the necessary sensitivity and range for comprehensive clinical use.

Purpose of the Study:

To design and develop a low-cost, reliable, and easily manufacturable maximal voluntary bite force sensor.
To validate the sensor's performance characteristics, including linearity, repeatability, and measurement range.

Main Methods:

Utilized an in-house acrylic laser cutting machine for sensor fabrication.
Designed the sensor for ease of assembly, calibration, and safe operation.
Investigated the relationship between applied force and the sensor's electrical resistance.

Main Results:

Demonstrated a good linear relationship between applied force and sensor resistance.
Achieved a wide measurement range of 0 to 700 N with low signal drift and excellent repeatability.
Observed a high signal-to-noise ratio for human bite force measurements.

Conclusions:

The proposed bite force sensor is a cost-effective and reliable solution for measuring human bite forces.
Its ease of fabrication and rapid deployment make it suitable for both research and clinical applications.
The sensor shows high potential for widespread use in diagnostics and therapeutic monitoring.
