The application will transform a smartphone into a peephole, letting you see who's at the door even if you're not at home. The device itself will be made of high-density polymer and will include an infrared camera able to capture video at both day and night. When visitor presses the LED illuminated push-to-talk button, the video and audio will be sent via the local Wi-Fi connection to the user's smartphone.

A new curved contact lens with a full display could one day project images and texts right in front of our eyes. The contacts will feature a spherical curved LDC display able to receive wirelessly projected images. It is believed that the lenses could be used in a variety of applications, including adaptable sunglasses and controlling light transmission to protect damaged retinas.

A new plastic able to flex while also resisting scratches could replace the glass currently used on smartphones. The plastic is made up of two separate layers--one that gives strength and another that resists fingerprints. The display has a pencil hardness of 9H and is not scratched even when scraped with 7 pounds of pressure from steel wool. In addition, the flexibility helps prevent the material from shattering if dropped and allows for a bendable display.

The wheel consists of a center layer of rubber that is stretched and held tightly by a series of rods, which can be adjusted for different types of terrain. The mountain bike version of the wheel includes 29-inch carbon fiber rims and is open on the sides, although it is being considered covering the opening with thin sidewalls to keep debris from getting caught in the tire. Besides eliminating the risk of flats, the wheel also helps increase performance by storing potential energy...

A new insulin delivery device will be the most secure remote-controlled medical device on the market. The device will carry a week's supply of insulin and work with the Android-powered phone. The phone will feature an integrated glucose meter and a dedicated SIM card for communication with the pump, and will operate for seven days on a single eco-friendly battery. A temperature sensor in the pump will warn the user if the insulin is being exposed to too much heat while a separate...

The tiny cam car key uses an infrared LED to create enough illumination to capture HD videos, even in the darkest corners. The tiny camera weighs under an ounce and measures only 2.5 inches on its longest side. Although it doesn't look much like a camera at all (instead resembling a remote car key), its features include motion-detecting activation, an 8 GB built in memory and audio recording capabilities.

By sending pressure waves along suspect pipes, it is possible to develop a way to quickly and more accurately locate leaks, particularly in plastic piping. The system can be attached to a standard water hydrant and will feature a valve that can be rapidly opened and closed to create a pressure wave that will travel down the pipe. When the wave encounters any unexpected defects in the pipe, such as a crack, it will bounce back a reflection that can be used to determine the location...

The new cycling system will let you use both your legs and your arms while riding. The bicycle will feature a separate drive train that will be powered by the arms and will work with the pedal system. This will allow the rider to also use their arm, shoulder, and chest muscles to create forward momentum and encourages a better, full body workout. The adjustable system can be set for different arm lengths and the tilting action of the hand crank steers the front wheel.

A new polymer that kills bacteria and germs when exposed to sunlight could open the door to a wide range of self-cleaning furniture and gadgets. The titanium dioxide-doped polymer coating works through an electrochemical reaction. UV light from the sun causes the titanium dioxide to produce free radicals, which degrade cell walls and cell DNA, thus destroying bacteria and fungi. Smudges and fingerprints also disappear from the material after an hour of exposure to sunlight.

Goggles able to display information about the area with color-coded outlines will make it easier for partial-sighted people to move through their environments. Visually impaired people often struggle with discerning contrast and depth. The new goggles will feature a pair of cameras mounted on a virtual reality headset and connected to a very small computer. The cameras will scan the area ahead of the wearer and convert the information to digital code sent to the computer. Using an...
