Via NZ Herald: 

The new, 1.55 millimetre-thick contact lens contains an extremely thin, reflective telescope, which is activated by winks.

Released in 2013 and fine-tuned since then, the prototype was unveiled by Eric Tremblay from the Ecole Polytechnique Federale de Lausanne in Switzerland at the American Association for the Advancement of Science annual meeting in California.

The lenses come with smart glasses that respond to the wearer's winks - but not blinks - so that the user can switch almost effortlessly from normal to magnified vision and back.

The wearer winks with the right eye to activate the telescope, and with the left eye to deactivate it.

It might sound like the stuff of science fiction, but a team of engineers at the California Institute of Technology (Caltech), for the first time ever, has developed just such self-healing integrated chips. The team demonstrated this self-healing capability in tiny power amplifiers. The amplifiers are so small that 76 of the chips—including everything they need to self-heal—could fit on a single penny.

Think about that for a moment: a flashlight that shines for as long as you hold onto it. No more scrambling for and chucking away AA batteries. It could have an immediate impact on more than 1.2 billion people -- one-fifth of the world's population -- who, according to the World Bank, lack regular access to electricity.

Stunningly, no one on record has thought to use thermoelectric technology to power a flashlight. But for Ann, peltier tiles, which produce an electrical current when opposite sides are heated and cooled at the same time, were a convenient solution to a friend's study problem.
