## Description

- description: Temperature gradients are widely used to drive and probe transport
    phenomena in solids, forming the basis of heat-to-charge conversion processes.
    In typical experiments, local heating is introduced to generate a temperature
    gradient, and the resulting electrical response is detected by separate electrodes.
    Such measurements usually regard heating purely as a source of thermal excitation.
    Here, we show that heating inherently generates mechanical stress through thermal
    expansion, which in turn produces measurable electrical signals via electromechanical
    coupling. Using quartz as a model piezoelectric system, we demonstrate that heat
    can be converted to electrical currents via thermally generated stress. The on-chip
    device used in our experiment enables us to probe the anisotropy of the piezoelectric
    tensor through the thermally generated current, exhibiting twofold and threefold
    responses for X-cut and Z-cut crystals, respectively. We further show that the
    response can be detected in both current and voltage modes. These results reveal
    a thermomechanical pathway for heat-to-charge conversion and establish a general
    platform for electrically probing thermomechanical responses in insulating materials.
