    Application
In summary, the conversation discusses the possibility of using a piezo-electric crystal to charge a small battery and connect it to a load. The problem is that the battery needs to supply current to the load for a short period and then be recharged by the crystal. The conversation also mentions some online resources and advice on how to build a self-charging battery using a piezo-electric plate. It is noted that piezo is a high-voltage, low current device.

Can I use the piezo-electric crystal to charge a small battery and connect the battery to a load.
The problem here is that the battery has to supply current to the load for a short period. Then it has to be recharged by the crystal. will I be able to use the same battery for charging and discharging?

The circuit for piezo-electric storage found in the internet is http://ej.iop.org/images/0957-0233/23/1/015101/Full/mst399991fig10.jpg

Should I directly connect the load to the battery.

Can I be able to feed back the vibration produced by the load to PZT and hence using it for charging the battery

1. What is the piezo-electric effect?

The piezo-electric effect is a phenomenon in which certain materials, such as quartz, generate an electrical charge when subjected to mechanical stress. This means that when pressure or force is applied to these materials, they produce an electric current.

2. How is the piezo-electric effect used in everyday life?

The piezo-electric effect has numerous applications in everyday life, such as in lighters, electric cigarette lighters, and gas grills. It is also used in ultrasound technology, sensors, actuators, and even musical instruments like guitars and pianos.

3. What are some industrial applications of the piezo-electric effect?

The piezo-electric effect is widely used in industries for various purposes, such as in pressure sensors, accelerometers, and piezo motors. It is also used in measuring devices, such as strain gauges, and in precision positioning systems.

4. How does the piezo-electric effect contribute to medical technology?

The piezo-electric effect plays a crucial role in medical technology, particularly in ultrasound machines. Ultrasound machines use piezo-electric crystals to generate sound waves, which are then used to produce images of internal body structures.

5. Is the piezo-electric effect reversible?

Yes, the piezo-electric effect is reversible, meaning it can also work in the opposite direction. When an electrical current is applied to piezo-electric materials, they can also deform or change shape. This property is used in piezo-electric actuators, which are used in micropositioning and nanotechnology applications.
