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.

Physical activity and sedentary time were assessed using a combined accelerometer/heart rate monitor.

GPS sensors revealed the paths that animals took to Dipteryx trees, while accelerometers confirmed that an animal was active, and potentially feeding, during a tree visit.

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.
