It used to be that only guys were really into new gadgets. After all, the James Bond films with the cool spy gear and the hot women were aimed at the male market. Guys secretly wanted to have a car with an ejection seat that could spit out an oil slick.

However, women are no longer the technophobes that some people seem to think they are. More and more women now work in the technology field, so inventors are coming up with cool gadgets that appeal to everyone – not just the teenage boy who never grew up.

Here is one that only women will appreciate though.

Color Changing Leather Shoes

There are many ladies who like to have shoes to match their favorite outfits. What fashion maven wouldn’t appreciate a pair of shoes that change color on their own? These shoes from the Footwear and Recreation Technology Research Institute of Taiwan change color when exposed to sunlight. They can be coated with a resin that consists of microcapsules with luminous particles. These particles change from pink to orange or purple about 30 seconds after coming into contact with sunlight. They only change for up to 60 hours. After that, the change will become permanent. The entire shoe may be coated or various portions to give one a chance to create a unique pair of shoes.

George Foreman USB iGrill

Just when you thought there were no more possible variations on a theme, the folks who make the George Foreman Grills have created one that plugs into the USB port on your computer. The iGrill uses current from the USB connection to charge high voltage capacitors, which in turn power the grill. Perfect for students and anyone who likes to be able to eat on the run.

USBCELL Batteries

Rechargeable batteries have been around for practically forever it seems, but these take things a step further. What is so cool about them? Pop the top off, and plug them into a USB port to charge. Made by Moxia Energy, currently they only sell the AA size. 9 volt, cell phone and device sizes are forthcoming.
