Claim:
1. A single-use bio-solution processing sensor, comprising: a fluid conduit through which a biopharmaceutical solution flows during use of the sensor; an on-sensor memory device; a usage counter associated with the sensor; said usage counter includes a motion detector, the motion detector detects vibration corresponding to solution flow through the fluid conduit, and the memory device analyzes the vibration and designates the vibration as a counted sensor use event, whereupon the counted sensor use event is stored on the memory device and accumulates with prior or subsequent use events until a maximum use total stored on the memory device is attained; and the motion detector is an accelerometer that operates as a flow meter, whereby when a relatively non-compressible fluid flows through the fluid conduit a first accelerometer output is generated, and when a compressible fluid flows through the fluid conduit a second accelerometer output is generated, resulting in a differential between the first and second accelerometer outputs, thereby indicating an end to a cycle of a manifold within which the sensor is included.
