The analysis of animal movement has held a long fascination for scientists. Since Eadweard Muybridge presented highspeed photographs of the flight phase in galloping horses in the late 19th century Muybridge, , there has been an escalating interest in animal locomotion through the study of kinematics, kinetics and neuro-muscular control Dickinson et al. If the force falls to zero, the foot has left the ground and is hence in swing. Further, despite the conceptually clear definition of footfall events by means of forceplate data, the exact timings of these events still depend on the set threshold at which one considers a force sufficient to indicate weight bearing. These thresholds tend to vary in the literature—for example, in human studies researchers have used a vertical force threshold of 20 N Hobbs et al. In humans, a force threshold of 20 N instead of 10 N for example may cause event detection to differ by only 5 ms Leitch et al.
With each passing year, the problem of the world's increasing energy needs, but decreasing energy supply becomes a greater worry for society. But this conundrum has also become a great inspiration for innovators like Laurence Kemball-Cook, CEO and founder of the London-based start- up, Pavegen. Over the last five years, Pavegen has iterated on a modular floor tile that converts the kinetic energy from a person's footstep into storable electricity. Is human generated electricity a viable solution to the energy crisis? The structure of a Pavegen tile allows it to compress an indiscernible 5 mm per footstep and produce up to 8 Watts of energy.
The electrical energy or electricity plays a very important role in almost all industries. Especially in the housing sector, it is a necessary element in construction, completing and maintenance of a building. Read more.. There are many sources are available to generate electricity.
Wednesday, 30 November Critical Literature Review. This paper will examine the potential of implementing kinetic floor tiles within aspects of an office development, both externally and internally. The combination of piezoelectric material  and footfall harnessing  can generate off-grid renewable energy, such power can then be utilised to operate lighting systems and electronic devices. The Pavegen floor tiles move a slight 5 millimeters when stepped on, capturing kinetic energy which is either stored in lithium polymer batteries beneath its surface or converted into watts of electricity and distributed throughout surrounding lights.
