A novel method for measurement of vertical and lateral forces with a high sensitivity and accurate gap control has been presented. It combines a double-ended tuning fork (DETF) resonator for the vertical force measurement with an optical fiber probe for the lateral force measurement. The theoretical and experimental investigations revealed that this method can provide simultaneous measurement for lateral and vertical forces of nanometer-gap lubrication with a precise gap of control within 1nm. In addition, the attained force sensitivity is of the order of 10nN. This method can be useful to clarify the nanolubrication or boundary lubrication phenomena, which has not been fully understood due to the difficulty of the measurement.
