A soft, flexible contact lens can monitor glucose levels in tears and deliver sensing results through the lens display, alerting the user if glucose levels are too high by turning off a tiny embedded LED light, according to a new report from UNIST, Korea.

The Solar Vertical Lamp, designed by Yoon-Hui Kim and Eun-Kyung Kim, takes an average vertical blind and embeds it with special mini photovoltaics and LED pixels. Close the blinds during the day and the miniature solar pads on the back of the blinds start to soak up the sun's energy. Once the sun goes down, artfully placed lighting pixels illuminate in certain parts of the blinds.
