Ultra-thin sheets of wood modified with nanocrystals can work as a shield against electromagnetic waves.
Electrical devices such as phones, laptops and microwaves produce electromagnetic radiation, which can disrupt electrical circuits, harming performance or stopping devices from working.
To stop this happening, electrical components are often encased within protective conductive materials, such as copper and aluminium, which can absorb and reflect electromagnetic energy.
