Apparatuses and methods for the haptic sensation of forces at a remote location. Groups of MEMS-based pressure sensors are combined into sensor arrays. In some embodiments, the pressure sensors are encased in silicone or other elastomeric substance to allow for routine use in the aqueous environment of the body. The sensor arrays may be housed in a No-compatible material (e.g., stainless steel, plastic) and may be attached to a printed circuit board to allow the electrical signal generated by the sensors to be communicated to a user. The sensor arrays may be used with faceplates that directly interact with the target tissue or object. The faceplates may be rough, smooth, serrated, or any other texture. The present apparatuses and methods are particularly well suited for robotic surgery and may be used in wherever haptic sensing of forces at a remote location is desired.
