Structures and sensor assemblies having engagement structures for securing a compliant substrate assembly

A structure for receiving a compliant substrate assembly, the structure comprising:

• an outer surface;
• a first set of engagement features extending from a first location of the outer surface, wherein the first set of engagement features are configured to receive a first rod of the compliant substrate assembly;
• and
• a second set of engagement features extending from a second location of the outer surface that is offset from the first location by a distance, wherein the second set of engagement features are configured to receive a second rod of the compliant substrate assembly, wherein the first and second rods are proximate first and second edges of the compliant substrate assembly, respectively.

A sensor assembly comprising:

• a base structure comprising:
• an outer surface;
• a first set of engagement features extending from a first location of the outer surface;
• and
• a second set of engagement features extending from a second location of the outer surface that is offset from the first location by a distance;
• a compliant substrate assembly comprising:
• a base layer;
• a deformable layer heat-sealed to the base layer such that the base layer and the deformable layer define at least one inflatable chamber;
• a first member proximate to a first edge of the compliant substrate assembly, wherein the first member is held by the first set of engagement features;
• and
• a second member proximate to a second edge of the compliant substrate assembly, wherein the second edge is opposite the first edge and the second member is held by the second set of engagement features such that the compliant substrate assembly is stretched over at least a portion of the base structure, wherein the first member and the second member are rods;
• and
• at least one pressure sensor fluidly coupled to the at least one inflatable chamber and operable to produce a signal indicative of a pressure within the at least one inflatable chamber.
