Georgia Tech develops self-charging battery that marches to the owner’s beat
One of the last times we saw the concept of a self-recharging battery, it was part of a high-minded Nokia patent whose ideas still haven't seen the light of day. Researchers at Georgia Tech are more inclined to put theory into practice. Starting from a regular lithium-ion coin battery, the team has replaced the usual divider between electrodes with a polyvinylidene difluoride film whose piezoelectric nature produces a charging action inside that gap through just a little pressure, with no outside voltage required to make the magic happen. The developers have even thumbed their noses at skeptics by very literally walking the walk -- slipping the test battery under a shoe sole gives it a proper dose of energy with every footstep. At this stage, the challenge mostly involves ramping up the maximum power through upgrades such as more squeezable piezoelectrics. Georgia Tech hasn't progressed so far as to have production plans in mind; it's nonetheless close enough that we could see future forms of wearable computing that rarely need an electrical pick-me-up.

So Apple could be working on an iPhone with a thinner display, you say. Look what we have here, possibly in the nick of time: it's a newly granted Apple patent for a screen with in-cell touch, where the LCD and touch recognition are integrated into one panel instead of stacking up in separate layers. Apple's implementation would slim things down by either having electrodes share duties, both driving the display and taking finger input, or stuffing two electrodes into each pixel to accomplish the same goal. The net effect isn't just one of squeezing a device into a thinner chassis; the company also envisions costs coming down by reducing the number of parts and streamlining the manufacturing process. As envisioned, the screen looks like an ideal fit for a significant revamp of Apple's mobile display technology, although we'd be careful about assuming that this or any in-cell touch implementation is a lock for potentially imminent iOS hardware. Apple first filed the patent in early June 2007, before the original iPhone had even marched into a retailer -- display technology has come a long way since then.
