Abstract:	Ultrasonic transducer was fabricated from silicon buckled membrane using a thermo mechanical excitation and piezoresistive detection. The transducer has a 4 mm square silicon membrane, buckled with an initial deflection of 20 μm, actuated by dynamically heating an aluminium ring layer, 3 μm thick, with a polysilicon ring resistor. Detection is made by measuring the piezoresistive component in the polysilicon layer impedance
