Trampoline paper appears in PRX!


Force measurements and optomechanics experiments typically call for lightweight, low-noise, and optically pristine mechanical elements. We have created delicate, nanogram-scale “trampoline” mechanical sensors that achieve a record 16 attonewton force sensitivity at room temperature (equivalent to the gravitational pull between two people 100 kilometers apart). These trampolines are furthermore compatible with the high-quality optical elements required for optomechanics experiments, in principle enabling laser light at the level of a single photon to strongly influence their mechanical trajectories.
