Amazing new technology powers wearable devices with our own sweat.

A team of engineers from the University of California, San Diego has developed remarkable stretchable power cells that take energy from your own sweat and power electronics, like LEDs and even Bluetooth radios! New technology powers devices with sweat
For a field that has been struggling to come up with devices that are powerful enough and stretchable enough, these epidermal biofuel cells are a major breakthrough. The breakthrough was achieved thanks to a combination of extremely clever chemistry, highly advanced materials and electronic interfaces. This combination let them build a highly stretchable, electronic foundation using lithography and screen-printing to manufacture 3D carbon nanotube-based cathode and anode arrays.
The biofuel cells are equipped with an enzyme that oxidizes the lactic acid present in human sweat to generate current. This turns the sweat into a source of power. Because the concentration of lactic acid in a person's sweat gets diluted over time, the team is exploring a way to store the energy produced while the concentration of lactate is high enough and then release it gradually.So future work is needed before this technology can be considered a full success.

Getting smart about Christmas lights in 2018.

Tuesday, November 20, 2018

Halloween came and went, and now, it's beginning to look a lot like Christmas! Well, once the decorating is finished, that is. One of the most visually pleasing parts of the season is all the festive lights in creative places on neighboring houses. But that type of effect isn't limited to just outdoors; lighting plays a big part in Christmas inside as well. A tree with no lights looks dimly like a big plant in the center of the room. That's until the carefully strung lights shine throughout the magnificent green (and sometimes even white) tree and show off what's adorned on the branches. To make sure you get the most of your festive lighting, this year make a switch if you haven't already too smart lighting with LEDs.
