Abstract
Embodiments of the invention include a temperature sensing device that includes a base structure that is positioned in proximity to a cavity of an organic substrate, an input transducer coupled to the base structure, and an output transducer coupled to the base structure. The input transducer includes a first piezoelectric material to generate vibrations which are transmitted on the base structure in response to input signals being applied to the input transducer. The output transducer includes a second piezoelectric material to receive the vibrations and to generate output signals which are used to determine a change in ambient temperature.
