We present torsional pendulums based on small bundles of single‐walled carbon nanotubes and ultimately on individual single‐walled carbon nanotubes. The nanotubes serve as mechanical support and torsional spring for a lithographically defined metal plate. The plate can be actuated in an electric field and the device is operated inside the transmission electron microscope. In comparison with previous works we have built mechanically much more fragile devices, i.e. almost three orders of magnitude heavier suspended metal structures, and metal blocks suspended on smaller diameter nanotubes.
