Abstract
Maximum bite force is an important factor to evaluate the masticatory system level of health and fitness. Dentists often take the maximum bite force as a reference in determining what actions should be perform in a patients. The aim of this study was to present a simple yet handy device for measuring human maximum bite force based on low-cost sensor. Flexyforce, which has suitable shape and size for human teeth, wide measurement range (up to 430 N), good linearity, fast response time (lower than 5 s) and high repeatability, was use as the chosen sensor. Low pass filter is employed to reduce the existing noise and eliminate drift that occur when sensor perform measurement. In addition, to ensure user convenience, the designed device utilized liquid crystal display (LCD) for visualize measurement result. Based on the conducted test, the designed human maximum bite force measurement device has an excellence performance. It shows through more than 90% in accuracy with the highest error percentage is 1.75% and the mean of error percentage is 0.57%.
