So, whats next?
With the rapid advances in technology in this modern era, the possibilities seem endless. We now have the ability to carry our lives in our pockets. Increased access to social media via our mobile phones provides us with a twenty-four hour connection to the world. The theory of the cyborg posed by Donna Haraway has come to exist, as society continues to entrench itself in technology. How much further can we involve ourselves within the technological revolution? Maybe we could tattoo our favourite electronic device on our bodies so we can have it wherever we go.
What if we were to take this idea one step further? How about placing a subcutaneously implanted touch-screen in our arm? It could operate as a cell phone display that has the potential for 3G video calls that are visible just underneath the skin and run on the person’s blood. Sound crazy? At the recent Greener Gadgets Design Competition, an engineer posed just this.
The basis of the 2x4-inch "Digital Tattoo Interface" is a Bluetooth device made of thin, flexible silicone. It is inserted through a small incision as a tightly rolled tube and then it unfurls beneath the skin to align between the skin and the muscle. Through the same incision, two small tubes on the device are attached to an artery and a vein to allow the blood to flow to a coin-sized blood fuel cell that converts glucose and oxygen to electricity. After blood flows in from the artery to the fuel cell, it flows out again through the vein.On both the top and bottom surfaces of the display is a matching matrix of field-producing pixels. The top surface also enables touch-screen control through the skin. The display uses tiny microscopic spheres, somewhat similar to tattoo ink but having the ability to change from clear to black. When the phone is activated the "tattoo" can be seen, but when it is not in use it is invisible.
The tattoo display communicates wirelessly to other Bluetooth devices - both in the outside world and within the same body. The device is always on, as long as your blood is flowing, but it can be turned off and on by pushing a small dot on the skin. When the phone rings an individual can turn the display on, and "the tattoo comes to life as a digital video of the caller," Mielke explains. When the call ends, the tattoo disappears.
Could such an invasive device have harmful biological effects? Actually, the device could offer health benefits. The device can actually monitor the body and pick up many blood disorders, alerting the person of a health problem. It can also measure blood sugar which could be helpful for managing diabetes.
The tattoo display is still just a concept, with no plan at this stage for commercialization. However, it is interesting to contemplate future technology and what it will allow us to do.
