Forcen Inc. has developed the ForceFilm System, a thin, conformal film that can be laminated, under a stiff material and its contact surface, without modifying the contact surface.
The ForceFilm System works by measuring strains in the underlying structure, and has a force resolution of as little as 10 mN.
The strain can be measured in multiple dimensions at multiple points, due to the array of sensors integrated into the thin ForceFilm.
The surface or part can be of any complex shape or geometry. It is integrated with a sealed electronics module that calibrates, measures, and converts the sensing array signals to noise-free force measurements.
These measurements are transmitted by digital wired bus for simple integration, and requires no modification to the components, robot, or assembly.
