Nanomechanical resonators were fabricated with chemical-vapor-deposited (CVD) graphene. The frequency response was analyzed in different bias and temperature conditions. It was observed that the resonance frequency decreases with increasing gate bias, showing the presence of a high built-in strain. Highly non-linear responses was observed in cryogenic temperatures, which can be partly attributed to higher strain in low temperatures.
