Abstract

Accurately measuring bite force is critical in dentistry, as it provides valuable insights for diagnosing dental conditions, planning orthodontic treatments, and designing durable prosthetics. While commercial Force Sensing Resistors (FSR) are widely used, they often lack the precision, adaptability, and personalized fit required for measuring bite force in diverse dental applications. Custom-made FSRs address these limitations by offering tailored designs that conform to the unique shapes and sizes of individual teeth, allowing for multiple active sensing areas and enhanced sensitivity. This research explores the development of a screen-printed Force Sensing Resistor (FSR) tailored for measuring dental bite force. The motivation stems from the need for accurate and flexible sensors to enhance the measurement of bite force in dental applications. The primary objectives are to design an optimized FSR, fabricate it using screen printing, and evaluate its performance parameters. Methodology involves an extensive literature review, design modeling using SolidWorks, finite element simulation analysis, and fabrication through screen printing on flexible substrates. Initial simulations indicate promising results in optimizing the sensor's sensitivity and resistive range. Simulation results show optimum design of Design 3 (width of 0.9mm) with lowest resistance due to highest contact width that create additional conductive pathways. Measurement results shows Design 6 (0.75 mm width with 4 active areas) yields the highest sensitivity 0.096 1/N with sensing range of 0 – 20N compared to other design. The project concludes with comprehensive groundwork for FSR fabrication, paving the way for practical testing and validation in subsequent phases to advance dental diagnostic tools.
