1. A 3D force sensor to detect the 3D direction of a contact force that can be non-parallel and non-orthogonal to the 3D force sensor surface and the 3D force sensors is comprised of;
- an exterior housing to be in touch with the contact force;
an interior housing located inside the exterior housing;
a plurality of sensors located between the exterior housing and the interior housing to track the movement of each corner of the exterior housing relative to the x, y, and z-axis due to the contact force, and generate a signal representing the movement; and
a microprocessor that receives the signals of the plurality of sensors and determines the 3D direction of the contact force.

Abstract
Disclosed is a 3D force sensor that can detect its orientation and the magnitude and 3D direction of a force applied to its surface. The force can be non-parallel and non-orthogonal to the surface of the 3D force sensor. A plurality of the 3D force sensors are simultaneously used to detect the orientation of an object and the magnitude and 3D direction of the forces applied to the object. Also, a plurality of the 3D force sensor can be used to detect the tilting of a vertical or horizontal stacking of a plurality of objects relative to one another.
