Conformable sensor assembly and system

A sensor assembly comprising:

• at least one stretchable layer including a stretchable substrate;
• at least one flexible layer including a flexible substrate coupled to the at least one stretchable layer;
• an actuation layer coupled to the at least one stretchable layer and the at least one flexible layer, the actuation layer including at least one contact pressure actuator for adjusting contact pressure of a target surface on the sensor assembly;
• and
• a control circuit in communication with the at least one contact pressure actuator, the control circuit configured to receive information on the contact pressure of the target surface on the sensor assembly from a trace and to adjust the contact pressure of the target surface on the sensor assembly via the at least one contact pressure actuator based on the information.

A sensor assembly comprising:

• at least one flexible layer, the at least one flexible layer having an elongation of break of greater than about 10 percent, the at least one flexible layer having conformability features;
• a first group of sensor elements printed on the at least one flexible layer;
• at least one stretchable layer, the at least one stretchable layer made from one or more materials having a modulus of less than about 60 megapascals (MPa) and an elongation of break of greater than about 25 percent, the at least one stretchable layer including a low pitch sensor element;
• and
• a second group of sensor elements printed on the at least one stretchable layer;
• wherein the first group of sensor elements and the second group of sensor elements form a plurality of sensor elements;
• wherein at least some of the plurality of sensor elements are disposed between conformability features of the at least one flexible layer.
