The Noise in Physical Systems (NiPS) (www.nipslab.org) Laboratory is a research facility within the Physics Department of the University of Perugia
. NiPS has a long-standing tradition in studying physical systems in the presence of noise. Scientific interest ranges from stochastic nonlinear dynamics modelling to thermal noise measurements.
Wisepower srl (www.wisepower.it) is a university spin-off company focussed on the design and prototypation of micro-energy generator. The company holds patents on vibration-to-electricity nonlinear conversion technology.
Noise
In common use, the word noise means any unwanted sound. In both analog and digital electronics, noise is random unwanted perturbation to a wanted signal; it is called noise as a generalisation of the acoustic noise heard when listening to a weak radio transmission with significant electrical noise...
