Implantable Electronics­ Dissolvable devices make better medical implants.

Implantable Electronics­

Implanted under the skin, an array of light-emitting diodes could signal the concentration in the blood of biomarkers such as insulin. Over time, the array will dissolve away, eliminating the need for surgery to remove the implant. Flexible silicon electronics (inset) are held in place with a silk film. Incorporating antibodies or enzymes into the film will allow devices to detect biomarkers.

Electronic Ink: LED Tattoos Implanted by Silk

Pretty kinky, but there are already practical applications being considered. The Illustrated Man. Tattoos have mostly been static graphics, limited in their usefulness in communication certain info. But researchers from the University of Pennsylvania have now come up with LED tattoos that can turn your skin into a living screen. I initially reported on the silk implantation in the forums, while Kenryouku_One gets props for the follow up on how the tech is being used to implant the LEDs. A silky entry. By building thin, flexible silicon electronics on silk substrates, researchers have made electronics that almost completely dissolve inside the body. Silk has been used before and is approved by the US Food and Drug Administration for medical use. Tramp stamp one second, instructions the next. It’s written all over your face… and the back of your wrist. Implantable Silicon-Silk electronics could mean LED tattoos.

Advancements in tattoo pigments and the refinement of tattooing equipment has seen an improvement in the quality of tattoos being produced. Today it’s possible to get ink that glows under UV light, but a new technology could see tattoos that emit their own light. Researchers have been able to build thin, flexible silicon electronics on silk substrates that almost completely dissolve inside the body, paving the way for embedded LED tattoos that offer much more than just aesthetic appeal. Implanted LED Tattoos May Become The Next Big Trend. While it may seem like tattoos are the norm now, no one has ink like this.

A team from the University of Illinois led by John Rogers has devised a method to actually install LED lights under the skin. The research, published today in Nature Materials, saw the team develop flexible arrays 2.5 μm thick and 100 x 100 μm square which are currently smaller than any commercially available array. In their research, the team printed circuits “directly onto a rigid glass substrate and then transferred them to an inexpensive biocompatible polymer called poly(dimethylsiloxane) (PDMS) to create a mesh-like array of LEDs and photodetectors.” In short, the university team has allowed LEDs to be placed under the skin while allowing for stretching and twisting by as much as 75 percent. As the whole substrate is encased in thin silicon rubber, the ‘LED tattoo’ is also waterproof. . + University of Illinois Via DVICE via PhysOrg Images from PhysOrg and Natural Materials.

LED tattoo. A light-emitting diode tattoo is a type of body modification similar to a tattoo, but specifically involves implantation of technologically based materials verses traditional ink injection into the layers of the skin.

LED tattoos are accomplished by a combination of silicon-silk technology and a miniature lighting device known as a light-emitting diode. While there is potential for many applications in the medical, commercial and personal domains, the technology is still in the development stage. Once the ability is attained to condense the parts of a LED to a small enough level, it will be possible for the tattoos to be implanted in humans. Technological limitations[edit] Current medical devices are limited by their isolation from the body and their placement on rigid silicon.[1] Current devices also contain gold and titanium which are required for electrical connections.

Sin embargo, siempre dice que implementar este tipo de tecnología es muy costoso y complejo. Este mito popular no es tan cierto ya que por aproximadamente 120 mil pesos chilenos ( 250 dólares) puedes crear tu propio panel solar, es fácil de hacer y además es mucho más liviano que los paneles tradicionales. Para crear tu panel solar de forma económica, necesitas los siguientes materiales: Placas solares. Se encargan a Estados Unidos, es mucho más barato importar y las placas tardan menos de 10 días en llegar.Kit para armar circuito de 30 celdas fotovoltaicas de 6×6 pulgadas.

Primero: Forma filas con las placas solares. Segundo: Aplica el compuesto químico sobre todo el panel (Resina Póxica).
