• A new energy harvester using vibro-impact nonlinear sink is proposed. Vibro-impact induced targeted transfer improves significantly the efficiency. The optimal harvesting efficiency resides in regimes with 1–2 impacts per cycle. VINES provides high density and robust over a certain level of noise. potential (VINES) investigated. Applying Signorini’s contact law, non-smooth dynamics first form...

A sensor network is made up of a large number of sensors with limited energy. Sensors collect environmental data then send them to the sink. Energy efficiency and thereby increasing the lifetime of sensor networks is important. Direct transfer of the data from each node to the central station will increase energy consumption. Previous research has shown that the organization of nodes in cluster...
