A capacitive-based soft sensor consists of two parallel plates separated by 4 mm distance. When a pressure is 8 N/m^2 is applied to the surface, the gap is changed to 3 mm. The areas of the plates are unchanged and is 12 cm. The relative permittivity (dielectric constant) of the material between the plates remains constant at 5. Determine the change in capacitance of the sensor when pressure is applied and not applied
