This film is a clear sheet with a transparent but electrically-conductive coating acting as invisible wiring. It is designed to be laminated between two sheets of glass. Electronic devices such as LEDs and infrared sensors can be embedded in the film, and the transparent electrical wires connect the embedded devices with their controller. The clear sheet doesn’t yellow, nor does it add a green cast to light passing through.
One 210 mm x 290 mm x 0.13 mm, A4-size LED film piece with five White LEDs (transformer not included). Ideal lighting with 9 to 12 VDC battery.

Electroluminescent tape
Electroluminescent Lamp, or EL, is a flat flexible plastic lamp that does not contain gas, filaments, mercury, or glass. It is extremely visible through smoke yet does not produce a glare. A light-emitting phosphor is sandwiched between two very thin flexible electrodes. One electrode is opaque while the other transparent, allowing light discharged from the thousands of tiny phosphor crystals to escape. This product is cool to the touch and meets UL as well as other agency safety requirements.
These systems are available in custom lengths as well as by the rollOne AC Indoor sample kit that includes a 1/2 in x 8 ft strip of blue colored electroluminescent light tape and a 20 V power supply.

Skin Conduction Switch
Uses your skin to activate a switch or transmit data
The circuit in this toy ball uses the conductive properties of human skin to activate itself when you touch your fingers to the metal contacts. You do not have to apply any pressure; the salt dissolved in the water stored inside of the human body makes you a conductor of electrical current.
Switches that are sensitive to human touch, as opposed to those that must be flipped or pushed, have several advantages. They are much less likely to wear out and they will not get dirty or stuck. But they do need direct contact with the skin, so they will not work through gloves or clothes.
The switch works with anything less than 1 million ohms of resistance (your body ranges between 1,000 and 100,000). It will even work if two people who are holding hands each touch one contact.
This kind of switch could be used as a safety feature on power tools to automatically turn off when you take your hand off the handle. Microsoft recently patented a method for using your body to transmit data. Imagine a watch communicating with a PDA or cell phone. One day digital business cards might be transmitted between two people during a handshake.
A small, ping pong ball-sized device with metal contacts used for the switch.

Air Muscle
Imitates human muscle
Nature can be a great source of inspiration. This is an actuator that works like to a human muscle—it contracts by thickening. Inside the black pouch is a balloon. High pressure air pumped through the tube inflates the balloon, causing the muscle to shorten by as much as 40%.
These artificial muscles can provide substantial pulling force for their small size; they can exert force 400 times their weight. Typical DC motors or pneumatic actuators can exert about 16 times their weight. The largest of the standard type air muscle is 11 inches long, weighs less than three ounces, and can lift 154 pounds.
These artificial air muscles work when twisted, bent around corners, or under water. They even have a similar power profile to human muscle—the force exerted decreases as it contracts, just like the strength of your biceps is at maximum when your arm is extended and decreases as your arm is bent.
If your product doesn’t include an air compressor to provide the 60 psi needed to actuate the muscle, you can modify the design and use a hand-pump like those found on a blood-pressure cuff.
Sample kit includes standard 15 cm (stretched) air muscle and other necessary items to demo technology.
