Abstract EN
The small force measurement is very important with development of the technology.
The electrostatic force is adopted, in which a pair of coaxial cylindrical capacitors generate the electrostatic force when a voltage is applied across the inner and outer electrodes.
However, the measured force will be covered by noise (creep, ground vibration, and air flow) and could not be measured accurately.
In this paper, we introduce the differential method to reduce the effect of noise.
Two identical parallelogram mechanisms (PM) serve as the mechanical spring.
One of the PM serves as the reference and another serves as the force sensor.
The common signal will be offset, and the difference signal will serve as output.
In this way, the effect of the creep will be reduced.
The measurement system of the electrostatic force was characterized by applying mechanical forces of known magnitude via loading weights of calibrated masses.
The uncertainty from voltage, laser interferometer, and capacitance gradient was estimated.
For the measured force, the relative uncertainty is less than 4% (kp=2).
