PVDF micro machining for the high resolution skin-like tactile sensors
2017
This work report PVDF micro machining process by RIE without much loss of its piezoelectric constant. L/S (70/130_μm) of fine structure was realized in this work with high etch rate. O 2 mixing feed gases of CF 4 , CHF 3 , SF 6 and 100 % of O 2 were used. At the condition of 100% O 2 gas plasma and at a higher of RF power, the better of surface state and higher of aspect ratio structure could be realized.
