Immediate to near future, we are talking about single digit nanometer size transistor and light emitting diode. That's actually very small, you can't see it with a conventional microscope let alone magnifying glass. I need a pair of contact lenses that could allow me to browse the internet for at least 2 hours when exposed to a healthy wifi signal, the electronic components such as display, antenna, processor with embedded graphic, random access memory for storing working data etc will be fitted inside a gas permeable flexible polymer. I'm missing a power source to supply ultra low wattage current to drive the comfortable super energy-efficient internet enabled contact lenses, what available technology today can I use for my lenses?
Compact and lightweight.
It must not melt or explode under any normal circumstances.
Must not obscure vision.
Must be rechargeable.
Built-in/ bonus points for exchangeable or support wireless charging!
Note: disregard energy consumption and handwave the antenna only.
