An ultrasonic diagnosis and therapy apparatus according to an embodiment may include an ultrasound output unit including a plurality of ultrasound output elements, a circuit board that can be attached and detached through a connecting board connected to the ultrasound output unit to determine a function of the ultrasound output unit, and a control unit configured to control a setting value of each of the plurality of ultrasound output elements, wherein therapy and diagnosis functions are selectively or simultaneously implemented by changing the circuit board. With the ultrasonic diagnosis and therapy apparatus, it is possible to selectively or simultaneously implement the therapy and diagnosis functions by selectively mounting different types of circuit boards that determine the type and function of ultrasound outputted from the ultrasonic transducers.

A membrane device includes a trench substrate having trenches and a membrane having wrinkles. The membrane is not bonded to the trenches of the trench substrate but is bonded to the surface of the trench substrate in the shoulders of the trenches. Hills and valleys are alternately arranged in the membrane along the trenches. The membrane device can be used in various applications (for example, sensors) based on variations in the electrical properties of the membrane caused by a change in the shape of the wrinkles (a change in the strain) of the membrane in response to a change in the internal or external environment of the trenches.
