Abstract
A system for estimating a position associated with a pre-tensioned active material without using a position sensor. The system includes an active material being transformable between a first state and a second state in response to a pre-determined stimulus and pre-tensioned to at least a pre-determined threshold, yielding the pre-tensioned active material. The system also includes a processing unit configured to perform various operations. The operations include obtaining a value for electrical resistance of the pre-tensioned active material. The operations also include estimating, using the electrical resistance determined, the position associated with the pre-tensioned active material.
