Abstract:
1. An apparatus, comprising: one or more heating elements; plurality of elongated beams; and one or more transverse beams; wherein the one or more heating elements comprise a heating element, wherein the plurality of elongated beams comprise a first and a second elongated beam, wherein the one or more transverse beams comprise a transverse beam; wherein the heating element is coupled with the first elongated beam; wherein the heating element induces a time-varying thermal gradient in the first elongated beam to cause one or more drive oscillations of first elongated beam; wherein a nodal point of the first elongated beam abuts a first face of the transverse beam; wherein a nodal point of the second elongated beam abuts a second face of the transverse beam; wherein the heating element cooperates with the first elongated beam to cause one or more drive oscillations of the second elongated beam.
