Quantum clocks, gyroscopes and accelerometers are large, bulky and incredibly expensive, with an accurate quantum clock costing around £100,000.

The study, titled "City bus seat vibration analysis using 6-axis accelerometer and gyroscope sensors," was recently published in leading science journal, Nature.

Hubble’s gyroscopes, which spin at 19,200 revolutions per minute, are extremely precise but finicky.

Known as piezoelectricity, the ability to trade between mechanical stress and electric charge can be harnessed widely in capacitors, actuators, transducers and sensors like accelerometers and gyroscopes for next-generation electronics.

Researchers have built a prototype fiber optic gyroscope for high resolution, real-time monitoring of ground rotations caused by earthquakes in the active volcanic area of Campi Flegrei in Naples, Italy.
