Structured Piezoelectric Composites: Materials and Applications

Doctoral thesis English OPEN
Van den Ende, D.A. (2012)

The piezoelectric effect, which causes a material to generate a voltage when it deforms, is very suitable for making integrated sensors, and (micro-) generators. However, conventional piezoelectric materials are either brittle ceramics or certain polymers with a low the... View more
