description Methods, systems, and devices for downhole evaluation using a sensor assembly that includes a sensor plate, wherein a surface of the sensor plate forms a portion of an exterior surface of a downhole tool. Methods may include submerging the surface of the sensor plate in a downhole fluid in a borehole; activating the sensor assembly to generate a guided wave that propagates along the sensor plate, wherein propagation of the guided wave along the sensor plate is dependent upon a parameter of interest of the downhole fluid; and using information from the sensor assembly relating to the propagation of the guided wave along the sensor plate to estimate the parameter of interest. Methods may include isolating an opposing surface of the sensor plate from the downhole fluid. The guided wave may be an interface guided wave or may propagate in the plate between the surface and an opposing surface.
