Does anyone know of any optically transparent (and preferably thin) piezoelectric materials I could use for a science fair project converting pressure on the glass of touch screens to electrical energy?
Baluncore said:Quartz.

Surfaces can be conductive and transparent. The voltage signal produced by quartz has a very low current. That means you can print many thin conductive patterns on the surface that measures the position of the contact.tenpinfaze said:I was looking for a way to use the piezoelectric quartz without having to metallize the top layer in order to utilize the electrical discharge.
Optically transparent piezoelectric materials are materials that have the ability to generate an electric charge when put under mechanical stress, while also allowing light to pass through them. These materials are commonly used in various applications such as sensors, transducers, and energy harvesting devices.
Optically transparent piezoelectric materials have a unique crystal structure that allows them to generate an electric charge when a mechanical force is applied. This is known as the piezoelectric effect. When the material is subjected to stress, the positive and negative charges within the crystal structure separate, creating an electric field.
The most commonly used optically transparent piezoelectric materials are zinc oxide (ZnO), lead zirconate titanate (PZT), and polyvinylidene fluoride (PVDF). These materials have high piezoelectric coefficients and are transparent to visible light, making them ideal for various applications.
Optically transparent piezoelectric materials have a wide range of applications, including touch screens, acoustic sensors, energy harvesting devices, and biomedical sensors. They are also used in smart windows, where they can generate electricity from mechanical vibrations caused by wind or rain.
One of the main advantages of optically transparent piezoelectric materials is their multifunctional capabilities. They can be used for both sensing and energy harvesting, making them highly efficient and cost-effective. Additionally, these materials are lightweight, flexible, and environmentally friendly, making them a desirable option for various industries.
