I have constructed the analytical model for the motional capacitance of a quartz-crystal tuning-fork tactile sensor. Especially, depicting the materials in contact with the senso's base as the Voigt viscoelastic body is new. I have derived the analytical formula for the motional capacitance of the electrical equivalent circuit of the sensor at resonance based on the law of energy conservation which the electrostatic energy in motional capacitance is equal to the sum of the strain energy of the quartz arm and the loss of energy of the materials in contact with the sensor's base. I can prove that the change in reciprocal motional capacitance is caused by the dynamic Young's modulus and viscosity of viscoelastic materials since the calculated values are approximately equal to the measured values of the change in reciprocal motional capacitance before and after the sensor's base comes into contact with neoprene rubbers and plastic materials. This work will be published in JJAP.

本文建立了石英晶体音叉触觉传感器运动电容的解析模型。特别是，描述与传感器基座接触的材料作为Voigt粘弹性体是新的。根据能量守恒定律，即运动电容中的静电能量等于石英臂的应变能和与传感器底座接触的材料的能量损失之和，推导出了传感器等效电路谐振时运动电容的解析公式。我可以证明运动电容的变化是由粘弹性材料的动态杨氏模量和粘度引起的，因为计算值与传感器底座接触氯丁橡胶和塑料材料前后运动电容的变化的实测值近似相等。这项工作将在JJAP上发表。
