Optimised piezoelectric energy scavengers for elder care

Low power wireless electronics requires portable and autonomous power sources. This motivates the interest in energy harvesting. Among the proposed solutions, vibration-based piezoelectric bimorphs are characterised by marked advantages. This work investigates the possibility to increase the specific power generation of piezoelectric scavengers by structurally optimising their shape. Analytical and FE simulations are performed allowing the proposed layouts to be compared. The advantages of optimised layouts are proven and discussed.
