Abstract
Systems and methods for making a marker. The methods comprise: disposing a resonator with a flat planar cross-sectional profile in a cavity formed in a first substrate partially defining a marker housing; sealing the cavity using a second substrate; placing a first bias element adjacent to the second substrate so that the resonator will be biased by the first bias element when the marker is in use to oscillate at a frequency of a received transmit burst; and using a physical structure in the cavity or a magnetic field passing through the cavity to reduce frictional forces between the resonator and at least the second substrate.
