A flexible modular skin sensor array can cover any surface of a robot. The skin sensor array includes a flexible mesh and a set of modular sensor panels that attached to the mesh. The skin sensor array underlies or is molded inside a skin membrane (e.g., silicone), and can flex and stretch with the skin. Each modular sensor panel has a communications chip and one or more sensors. A master controller provides communications with the modular sensor panels through a shared bus. Modular sensor panels can fail without affecting the network. The flexible mesh and modular sensor panels may be made of flexible PCB, to accommodate movement of the skin. A set of convoluted bridges connect locations at which the modular sensor panels attach, allowing for flexing and stretching without tearing of the flexible mesh. The redundancy allows some of the connection leads to fail without affecting communications.
