An accelerometer having a substrate with a cavity therein, a heater wire extending over the cavity, a pair of temperature sensor wires extending over said cavity equidistant from said heater, and means for passing electrical current through the heater so as to develop a symmetrical temperature gradient in the fluid extending outwardly from the heater to the two temperature sensors. The fluid may be a liquid or a gas surrounding the heater and temperature sensors. Applied acceleration disturbs this symmetry and produces a differential temperature between the two temperature sensors proportional to the acceleration.
