A sensor may include a bladder, and a deformable conductor disposed on the bladder such that deformation of the bladder causes deformation of the deformable conductor, wherein the bladder is constrained so as to enhance the deformation of the conductor in response to the deformation of the bladder. A method may include applying a stimulus to a bladder having a deformable conductor attached thereto, detecting a change in an electrical characteristic associated with the deformable conductor in response to the stimulus, and selectively constraining the bladder to amplify the change in electrical characteristic in response to the stimulus.
