Vibrational piezoelectric energy harvesters (vPEH) are of great interest in several fields such as autonomous sensors and wireless sensor networks, bird tracking devices, or autonomous miniaturized robotic systems. They capture energy from mechanical vibrations available in the ambient environment a…
Piezoelectric materials based actuators are highly recognized for the development of microrobotic systems thanks to their high bandwidth, high resolution and high force density. However, one of their main drawback is the low relative stroke (0.1% of actuator's size) that limits the actuator motion r
In this letter, piezoelectric plate energy harvesters are designed by using topology optimization algorithm to harvest the excitation from different directions. The goal is to minimize the volume and weight of the whole structure so the harvesters can be used in small scale applications. To this aim
