Oki Printed Circuits Co Ltd showed an exhibit on a technology to embed a 170μm-thick thin-film all-solid-state lithium-ion (Li-ion) rechargeable battery in a printed board at JPCA Show 2010, which runs from June 2 to 4, 2010, in Tokyo.
So far, there have been many printed boards embedded with passive or active devices, but few printed boards have come equipped with energy devices, the company said.
Now this is interesting :D.
