We propose and theoretically demonstrate a mechano-optical nano-antenna over a broad temperature range. We show that there is a tunable, temperature-dependent plasmonic resonance associated with the nano-antenna geometry. We also theoretically demonstrate a matching condition for mechanical properties that is essential for maximizing thermal expansion differences across a broad temperature range. We expect that mechano-optical nano-antennas should allow for spatiotemporal temperature mapping in applications where precise measurement of local temperature is needed in real time.
