23. Energy scavenging apparatus comprising:
-
a frame which can be human-carried or human-borne;
plural piezoelectric members connected to the frame in a manner to cause vibration of the piezoelectric members as a result of human footfall and to generate output power;
an amplifier for amplifying the vibration of the piezoelectric members. - View Dependent Claims (24, 25)

26. An energy scavenging apparatus comprising:
-
a housing for defining a chamber;
two resilient assemblies positioned proximate respective two ends of the chamber;
a mass member situated for reciprocating motion in the chamber between the two resilient assemblies;
wherein each of the two resilient assemblies comprise a piezoelectric member which, when deflected by the mass member, produces a voltage and which replies to the reciprocation with a spring force to facilitate further reciprocation. - View Dependent Claims (27)
