We investigate use of nanomechanical torsional resonators for frequency-shift-based infrared (IR) thermal sensing. Nanoscale torsion rods, ~1μm long and 50-100nm in diameter, provide both extraordinary thermal isolation and excellent angular displacement and torque sensitivities, of order ~10-7 rad.Hz-1/2 and ~10-22 (N.m) Hz-1/2, respectively. Furthermore, these nanorods act as linear torsional ...
