| Abstract: | The half coated metal core piezoelectric fiber(HMPF)is one of the new type of piezoelectric devices for sensors.The mechanical model was derived when an HMPF worked as a dynamic micro force sensor.When an external harmonically varying micro lateral force is applied at its tip of a cantilevered HMPF,the electric charge of the sensor were calculated based on the piezoelectric constitutive equations and the vibration theory,and by using the average distributed electrical charge method.The effects of the radius... |
