Using Non-Newtonian Fluids to Enhance Phone Screen Protection – Physics World

Phone screens are constantly at risk of damage from falls and impacts. One solution to protect them is by using non-Newtonian fluids. These fluids change their properties when they experience sudden force or impact, becoming solid and absorbing the energy rather than allowing it to be transferred to the screen.

This technology is based on the principle of shear thickening, where the viscosity of a fluid increases as shear stress is applied. Non-Newtonian fluids, like cornstarch mixed with water, can be used to create a protective layer on phone screens that becomes harder on impact, forming a barrier to protect the screen from shattering.

The use of non-Newtonian fluids to protect phone screens is a practical application of physics principles. These fluids can provide a cost-effective and lightweight solution to enhance the durability of phone screens without compromising the touch sensitivity of the device.

In summary, non-Newtonian fluids can be an innovative way to protect phone screens from damage by absorbing and dissipating impact energy. This technology is based on the principles of shear thickening and provides a practical and effective solution for enhancing the durability of phone screens.
