Abstract
The amplifier assembly includes a driver bellows and an output bellows. The driver bellows includes a first end and a second end. The first end is positionable adjacent a microactuator. The output bellows includes a first end and a second end. The first end of the output bellows is securely attached to the second end of the driver bellows. The second end of the output bellows is positionable adjacent a device to be actuated. The output bellows has a smaller volume than the driver bellows. Each bellows is filled with a working fluid. When the driver bellows is compressed by the microactuator the fluid displacement of the driver bellows is translated to the output bellows causing a displacement in the output bellows equal to the fluid displaced in the driver bellows. Thus, an amplified output stroke is provided of the desired magnitude.
