A sustainable green energy needs is increasing. Meanwhile the energy itself is not always available compare to the needs according to its sources. According to Ministry of Energy and Mineral Resources data on their twitter account by April 7th 2018,consumable electricity reached around 1,128 KWh/Capita as per 2018. Meanwhile, the use of renewable energy source still as low as 12,15% compare to fuel and fossil sources. This will increase as many electric appliances usage keep grow exponentially.

One of the most rapid activities in normal human life is footstepping. Either walking, jogging, running or dancing footsteps activities needs a lot of energy and residues into body heat or sweats. This potential waste energy can be recycle into another form of usable energy.Piezoelectric floors generate many microwatts up to many watts per step, depending on pedestrians’s frequency and piezoelectric technology. Several feasibility studies has been proposed, such as high pedestrian public space and low pedestrian private space. Another report shows that piezoelectric pavement can also be design for intelligent road and all kind of information board, light, etc. All of this possibility begin with scavenging the human activities.
Another application of piezoelectric energy harvester found. The idea still using piezoelectricity phenomenon when it got pressed or vibrated by raindrops, vibration, pavement pressure, highway pressure etc.
