“…For this reason, a piezoelectric highdynamic process force dynamometer was especially developed and presented in Transchel et al [27]. This MicroDyn dynamometer is a three component process force dynamometer possessing a lowest natural frequency of f 0 ¼15.8 kHz, which allows accurate measurements of existing process forces during an interaction sequence of a single diamond grain.…”

“…According to the converse piezoelectric effect, if an electric field is applied on the piezoelectric materials, the piezoelectrics will generate a mechanical strain. Due to E (1) n generated by the stress T j , an additional strain S (2) i is produced. The secondary converse piezoelectric effect occurs on the piezoelectric quartz.…”

“…That is to say, the effect of the induced electric field E (1) n is always opposite to that of the stress T j which induces E (1) n . Due to the additional piezoelectric strain S (2) i , tertiary direct piezoelectric effect still occurs on the piezoelectric quartz to generate an additional electric field E (3) n .

The sensitivity enhancement of piezoelectric force sensors is investigated based on multiple piezoelectric effects in this paper. At first, theoretical analysis showed that multiple piezoelectric effects had an influence on the piezoelectric force sensors. Secondly, a practicable method was adopted to perform the experimental validation and quantify the influence of multiple piezoelectric effects. In the method, different capacitors whose capacitances became much larger than that of the piezoelectric quartz sensor were in parallel with the quartz sensor. With the method, the details of the sensitivity enhancement of piezoelectric sensors were obtained. Experimental results showed that the sensor sensitivity increased from 4.00 pC/N to 4.07 pC/N when the capacitance of parallel capacitors was increased from 500 to 1000 and then 5000 times of that of the sensor. The force sensor sensitivity was improved by 1.75%. However, the nonlinearity and repeatability error of the force sensor were markedly increased with increasing the capacitance of the parallel capacitor. The method demonstrated that the piezoelectric force sensor sensitivity could be enhanced to a certain extent in the practical engineering, but it also brought some negative effects. Finally, further analysis indicated that multiple piezoelectric effects influenced the sensitivity by changing the piezoelectric coefficient. The well-known piezoelectric coefficient d11 of the quartz could actually reach 2.35 pC/N.
