Multidirectional Cylindrical Piezoelectric Force Sensor: Design and Experimental Validation

Sensors, 2020
A common design concept of the piezoelectric force sensor, which is to assemble a bump structure from a flat or fine columnar piezoelectric structure or to use a specific type of electrode, is quite limited.
