For many researchers and scientists, the Holy Grail when it comes to power for mobile electronics and other devices is to harness the natural energy of our bodies rather than relying on batteries.
An engineer named Jim Mielke has invented a display that is wireless and powered by blood. The display would be implanted into the body between the skin and the muscle as a tight roll. According to Mielke the roll would then unfurl and position itself between muscle and the skin.
Once unfurled, the display would get its power from the blood. Specifically a small fuel cell would have leads hooked up to an artery and a vein allowing for blood to flow through a blood fuel cell that converts the oxygen and glucose in the blood into electricity.
The display is currently only a concept and was designed for the Core77 Greener Gadgets Design Competition. It has top and bottom display surfaces with matching matrixes of field-producing pixels. The top of the display will also act as a touch-screen control interface linked to other electronic devices via Bluetooth.
The device could be used as a tattoo to display ever changing custom artwork on the body and unlike existing tattoos; this one can be turned off by pressing a small dot on the arm. The small 2 x 4-inch display could also be used as a secondary display for a mobile phone and allow the user to see video of the caller or text information right on the skin.
Mielke says, “[When a call comes in] the tattoo comes to life as a digital video of the caller. When the call ends, the tattoo disappears.” Some may see the use of an invasive display to be potentially harmful. However, Mielke says the device could also be used to warn users of blood borne illnesses. This could be a great device for continuous monitoring of blood glucose levels for diabetics.
This is the second device DailyTech has reported on this week that has to do with blood. Some HOV lanes in the UK are being outfitted with cameras that detect the amount of blood inside a vehicle to determine if more than one person is in the vehicle.
