Week: 564.5 Guest: Dr. Neil Gershenfeld, MIT's Media Lab & Things That Think Topic: High tech, low cost medical monitoring Producer/Host: Steve Girard

NEMA: Smart materials for medical monitoring...coming up...

SPOT: NEMA...the National Emergency Medicine Association...fights our worst health enemies - heart disease, stroke, trauma. Call 800-332-6362.

NEMA: One of the cutting edge medical technologies out of MIT concerns remote sensing of smart materials....Dr. Neil Gershenfeld....

GERSHENFELD: using interesting materials to replace chips. So that then you can have things like a smart syringe that can measure who got how much of what? But all you've done to the syringe is build interesting materials into it.

NEMA: with what materials?

GERSHENFELD: ... magneto elastic metallic glass...that's what it's called. And when you excite it with a weak, or a low frequency magnetic field, it essentially sings...it resonates in a very characteristic pattern that let's you detect it..

NEMA: How does it work?

GERSHENFELD: You can encode information in the resonance structure, so by placing one of these materials in proximity to a syringe, it's response depends on the liquid in the syringe.

NEMA: Gershenfeld says the technology could be used to check on the amount of insulin a diabetic gives himself...and make other types of monitoring more consistent. I'm Steve Girard at The Heart of the Matter.
