Abstract

High resolution digital radial encoders (either incremental or absolute) are often not cost effective or small enough when used in conjunction with modern cost effective hybrid circuitry. In many applications, sensor costs are far greater than the supporting control system. The piezoelectric rotary sensor depicted in Figures 1,2A and 2B, could offer unique solutions to cost effective, manufacturable, miniature incremental encoding.
