Injectable Micro Devices for Chronic Pain

An innovative health company called “Microtransponder” is developing a tiny device – about the size of a grain of rice – that will be injected into patients and will stimulate their nervous system in ways that are shown to reduce chronic pain, help with Tinnitus, and address other medical problems that have typically used more invasive or more elaborate procedures.

In congressional testimony the Microtransponder CEO explained the device and how it can be injected and will stimulating nerve cells.    The entire mechanism is not well understood and the device is still in an early testing phase, though results so far appear to be promising.

Technology Review has more about this innovative health technology, suggesting:

The idea is that the electrical jolts delivered by the device override the neural pain signals being transmitted to the spinal cord.

Freeplay’s Humanitarian devices – remote technologies for great causes

One of my *favorite* companies at CES was Freeplay with several innovative humanitarian technology solutions as well as their innovative line of self-powered lanterns, radios, and more.

As part of their Foundation Work, Freeplay is building cheap, self powered devices for remote medicine in developing world and another device to charge One Laptop Project computers.   Below are three such devices – all self powered.    Emergency Radio, One Laptop Per Child Power crank (I’m not clear if this is better than the one built into those devices but I think it’s to be used for OLPC plus other devices), and one of the best innovations at CES 2009 which is an inexpensive fetal heart monitor to be used by nurses and doctors in the field to help lower infant mortality.    Freeplay’s work in this field will help save thousands of lives very cheaply because the lack of such medical data in the field is a key reason for the high mortality rates in the developing world.
