Even the Wikipedia entry[1] seems to list examples, most of which don't entirely rely on the flexibility of the device. I can understand the need for space savings, but that seems to be achievable for most of these applications without the flexible component.
For most wearables I've seen (clothing or devices worn directly on the body), FPCs don't seem to solve anything - you still have some bulky components, and the truly flexible parts need to be handled with extra care so as not to damage connections. I mean, clothing with built-in fitness monitoring (or GPS or whatever) sounds cool, but current implementations really seem to miss the practicality ("how am I supposed to wash this again?") of truly "invisible" technology.
Can someone point me to some better practical applications?
