    Some ideas around why we created @motmedu Looking for a conference with a difference? What story do you have to tell? The #motm13 Unconference is built around stories for the purpose of making strong connections with other passionate educators who are integrating ICT with pedagogy.

Medical devices powered by the ear itself - MIT News Office - 1 views

  • Health Sciences and Technology (HST) demonstrate for the first time that this battery could power implantable electronic devices without impairing hearing.
  • The devices could monitor biological activity in the ears of people with hearing or balance impairments, or responses to therapies. Eventually, they might even deliver therapies themselves
  • “In the past, people have thought that the space where the high potential is located is inaccessible for implantable devices, because potentially it’s very dangerous if you encroach on it,” Stankovic says. “We have known for 60 years that this battery exists and that it’s really important for normal hearing, but nobody has attempted to use this battery to power useful electronics.”

  • The ear converts a mechanical force — the vibration of the eardrum — into an electrochemical signal that can be processed by the brain; the biological battery is the source of that signal’s current. Located in the part of the ear called the cochlea, the battery chamber is divided by a membrane, some of whose cells are specialized to pump ions. An imbalance of potassium and sodium ions on opposite sides of the membrane, together with the particular arrangement of the pumps, creates an electrical voltage.
  • Low-power chips, however, are precisely the area of expertise of Anantha Chandrakasan’s group at MTL
  • The frequency of the signal was thus itself an indication of the electrochemical properties of the inner ear.
  • in cochlear implants, diagnostics and implantable hearing aids. “The fact that you can generate the power for a low voltage from the cochlea itself raises the possibility of using that as a power source to drive a cochlear implant,” Megerian says. “Imagine if we were able to measure that voltage in various disease states. There would potentially be a diagnostic algorithm for aberrations in that electrical output.”
  • “I’m not ready to say that the present iteration of this technology is ready,” Megerian cautions. But he adds that, “If we could tap into the natural power source of the cochlea, it could potentially be a driver behind the amplification technology of the future.”

    "For the first time, researchers power an implantable electronic device using an electrical potential - a natural battery - deep in the inner ear."

    "All of D-Lab's classes assess the needs of people in less-privileged communities around the world, examining innovations in technology, education or communications that might address those needs. The classes then seek ways to spread word of these solutions - and in some cases, to spur the creation of organizations to help disseminate them. Specific projects have focused on improved wheelchairs and prosthetics; water and sanitation systems; and recycling waste to produce useful products, including charcoal fuel made from agricultural waste."

    A new concept is starting to appear in encryption services for data and messaging: zero knowledge. Providers of such services claim that they do not know who you are, and that they never store the encryption key anywhere outside of your device. One such service from FoxyFone of Switzerland (a country famous for bank security and secrecy) is now available on the Apple App Store for the iPhone, iPod Touch, and iPad. The app, Foxygram, lets the user encrypt data on the device, including contacts, email, pictures, and video, with 256-bit AES security.
