This document summarizes a student project proposal to develop a piezoelectric generator that can recharge batteries using mechanical energy from footfalls. The project aims to address Pakistan's electricity shortages by generating cheap domestic power. Piezoelectric materials generate electricity from applied mechanical stress. The proposal outlines objectives to simulate a piezoelectric energy harvesting circuit in software and produce electricity from piezoelectric sensors. Potential applications include gyms, malls, and train stations with many footfalls. The proposal provides timelines and milestones to complete background research, circuit design, hardware assembly, and reporting over a 10 month period.

2. Motivation
• To promote non-conventional energy
• Produce electricity at cheapest cost for domestic use

3. Introduction
• The word originates from the Greek word
"piezein", which means "to press". Discovered
in 1880 by Pierre Curie in quartz crystals.
• Piezoelectric are materials that can create
electricity when subjected to a mechanical
stress.
• The word piezoelectricity means electricity
resulting from pressure.

4. Problem Statement
• In Pakistan the demand of electrical energy is
more than the daily energy produced so we are
facing shortfall of electricity. People use
rechargeable batteries (UPS) or diesel/petrol
engine(generators) to fulfill their demands, but
the fuel for these generators are too much
expensive.

5. Problem Solution
• To overcome this issue we will use the
cheapest way to generate electrical energy
using piezoelectric material (convert
Mechanical stress into Electrical Energy).

6. Objectives
• Simulate the circuit using Matlab/ proteus
• To produce electricity using piezoelectric sensors

7. Application
• In gyms where people
can exercise and create
more power.
• In shopping malls where
people can walk and
generate power.
• In train stations because
there’s usually high
density of people, so it
can be effective.
