A connector (20) for connecting modular tiles, each tile having an underside, the connector comprising: a. a film (22); b. an adhesive (24) on a side of a film (22), wherein the adhesive (24) is capable of forming a bond with the undersides of the tiles so that, when the connector spans adjacent edges of adjacent tiles so that the adhesive contacts the undersides of the adjacent tiles, the adhesive prevents relative movement between the adjacent tiles; and c. a sensor capable of sensing one or more of pressure, moisture, pH, and temperature.
