Bite force measurement is an important parameter when checking the function and integrity of the masticatory system, whereas it is currently very difficult to measure bite force during functional movement. Hence, the purpose of this study is to explore the potential technique and device for the measurement and intervention of the continuous bite forces on functional and dynamic occlusal condition. A portable biosensor by sandwich technique was designed, and the validity, reliability, and sensitivity were determined by mechanical pressure loading tests; meanwhile, the pressure signal is acquired by, and transmitted to, voltage changes by the electrical measurements of the sensors. The result is that, when the mechanical stress detection device is thicker than 3.5 mm, it shows relatively ideal mechanical properties; however, when the thickness is less than 3.0 mm, there is a risk of cracking. Mechanical stress changing and voltage variation had a regularity and positive relationship in this study. The mechanical stress-measuring device made by medical and industrial cross has a good application prospect for the measurement of bite force during function.
咬合力测量是检查咀嚼系统功能和完整性的一个重要参数，然而，目前在功能运动期间测量咬合力非常困难。因此，本研究旨在探索用于测量和干预功能和动态咬合状态下连续咬合力的潜在技术和设备。通过三明治技术设计了一种便携式生物传感器，并通过机械压力加载测试确定了其有效性、可靠性和灵敏度；同时，传感器的电测量将压力信号获取并转换为电压变化。结果表明，当机械应力检测装置的厚度大于 3.5 毫米时，它表现出相对理想的机械性能；然而，当厚度小于 3.0 毫米时，存在开裂的风险。在本研究中，机械应力变化和电压变化具有规律性和正相关性。这种由医疗和工业交叉制造的机械应力测量装置在测量功能期间的咬合力方面具有良好的应用前景。
