You are designing capacitive-sensing technology capable of detecting respiratory motion with high temporal frequency of 200Hz. You are acquiring 200 data points per second. The system does not require contact with the patient. For a 0.5cm^2 capacitive sensor, R is 100M. Calculate the plate spacing, x, required to pass the frequencies above 200Hz. Note the dielectric constant of free space is 8.854x10^-12F/m and dielectric constant of the insulator is 1.0
