We demonstrate theoretical and physical agreement and characterize the most relevant performance parameters with a device with 1. 5mg/Hz acceleration sensitivity, a 2. 5 fm/Hz1/2 displacement resolution corresponding to a 17. 02 ug/Hz1/2 force-equivalent acceleration, and a 5. 91 Hz/nW power sensitivity, at the thermodynamical limits.
