I've heard say its better & cheaper. Tooo expensive? I cant believe the price of gyros, and thier scarcity. I wonder when Analog Devices, Motorola, or another sensor manufacturer will produce a decent micro-machined gyro, similar to the ADXL accelerometer's. I read article a few years back that said they're past due by now. I tried making my own piezo-gyro awhile back, glueing a resonant nail segment to a $1 piezo disk, the electrodes of which I segmented to drive it in its 2nd mode, around 8KHz. Found it was sensitive to angular momentum, but unfortunatly, to minute temperature changes, any vibrations, or even a subtle change in pressure on the thin copper wires and disk mounting-such as touching the circuit board it was on. It even produced a chaotic vibration mode as the adhesive failed. That was enough for me!
