Kouichi Okamoto’s ‘bookmark light’, developed with the help of the University of Tokyo’s Business Venture Agic Inc., is a unique take on the traditional bookmark.
You can turn the bookmark light on and off by simply pressing a button on the thin device, thanks to conductive ink to transfer electricity by way of a lithium coin battery.
As one could probably infer from the name bookmark light, the gadget can work as either a reading/night light, or obviously a placeholder in a book.
The device’s clear display highlights the technology behind it, which includes a grid that features nano-size silver particles between a layer of film that forms the liquid crystal.
For some, this might be a bit much for a simple bookmark, but it definitely looks neat.
However, I would argue this product was invented for a shrinking market seeing as how more and more people are doing their reading on electronic devices these days.
