  text: The back-action damping of mechanical motion by electromagnetic radiation
    is typically overwhelmed by internal loss channels unless demanding experimental
    ingredients such as superconducting resonators, high-quality optical cavities,
    or large magnetic fields are employed. Here we demonstrate the first room temperature,
    cavity-free, all-electric device where back-action damping exceeds internal loss,
    enabled by a mechanically compliant parallel-plate capacitor with a nanoscale
    plate separation and an aspect ratio exceeding 1,000. The device has 4 orders
    of magnitude lower insertion loss than a comparable commercial quartz crystal
    and achieves a position imprecision rivaling optical interferometers. With the
    help of a back-action isolation scheme, we observe radiative cooling of mechanical
    motion by a remote cryogenic load. This work provides a technologically accessible
    route to high-precision sensing, transduction, and signal processing.
