“…The piezoelectric disks connected in parallel produced higher current output under identical loading conditions. In their latest study, two stress‐based PEH prototypes have been developed: prototype I consisted of 4, 8, and 16 numbers of 8‐mm‐diameter cylindrical piezoelectric elements sandwiched between two copper plates, while prototype II consisted of a stack of 11 number of 50‐mm‐diameter piezoelectric elements connected in parallel by alternating their polarities. The annual harvesting power was estimated to be 360 and 171 Wh for prototypes I and II, respectively.…”

“…Se concluye como óptimo para enterrar en asfalto el arch Bridge generando 286 V con 0,7 MPa de presión [59] 2016 Se mide directamente sobre un resistor la respuesta eléctrica de un prototipo formado por 4, 8 ó 16 cilindros piezoeléctricos sometiéndolo a ensayos de compresión uniaxial en laboratorio [60] 2018 Se complementa el trabajo [60] comparando con una nueva disposición en pila de 11 elementos. Se anuncia una producción en el primero de 360 Wh y de 171 Wh en el segundo anualmente [61] 2016 Basado en los trabajos de tesis doctoral (2014) del primer autor en la que se realiza un estudio muy interesante sobre la degradación de los piezoeléctricos. Instalación real en carretera de EEUU sobre la que se miden 3,106 mW con un aprovechamiento del 14% de la presión ejercida [62] 2016 Se presentan dos prototipos, el primero con 25 elementos y el segundo con uno.…”
