Abstract

Disclosed is a tire mountable apparatus and method that includes a substrate defining a longitudinal direction, a top surface and a bottom surface. The substrate has a plurality of conductor terminals arranged in a substantially linear relationship. A first support element is located below the bottom surface of the substrate and a second support element is located above the top surface of the substrate. The plurality of conductor terminals are positioned between the first and second support elements. The substrate may be a piezoelectric device having a piezoelectric layer arranged between first and second conductive layers. The plurality of conductor terminals may be arranged in a substantially linear relationship along a line about 80° to about 100° to the longitudinal direction of the substrate, and the longitudinal direction of the substrate being substantially perpendicular to the direction of rotation of the tire.
