CONTACT LENSES THAT CAN TALK TO YOUR PHONE

The video introduces interscatter communications, a technology that allows devices like contact lenses and brain implants to communicate with smartphones by converting Bluetooth signals into Wi-Fi. This technology could revolutionize medical management, such as monitoring diabetes through smart contact lenses. However, power constraints pose challenges, which are addressed by reflecting existing signals to save energy. Beyond medical uses, interscatter can facilitate applications like bill splitting with credit cards. The video concludes with a humorous anecdote about a declined credit card.

Explain how the new technology reduces energy consumption compared to conventional methods.

In what ways can this technology be applied beyond medical uses?
