Abstract
An analog floating-gate (AFG) inclinometer where a plurality of AFG sensors are provided to detect the presence of a discharge caused by settling of a conductive liquid droplet contained in a sealed microchannel under gravity. A plurality of sensor port electrodes associated with the AFG sensors are placed along the length of a curved sealed microchannel of the inclinometer at specific positions calibrated to corresponding angular inclinations. Discharge detected at a specific AFG sensor port during measurement due to the movement of the conductive liquid droplet under gravity is used in determining a surface inclination being measured.
