Chevy had the whole "Heartbeat of America" thing cornered in the 80s, but now its Ford's turn to get in on the action. The car maker's European research team unveiled a prototype car seat capable of monitoring a driver's heart courtesy of six embedded electrodes, which can take measurements without coming in direct contact with skin. The technology, the latest in a recent string of health-related in-vehicle concepts from the company, can detect whether the driver is having a heart attack and transmit that information to the vehicle's safety system. According to the researchers, the system is already highly accurate in its prototype state, making correct readings for 98 percent of drive time with 95 percent of the drivers tested. For more information on the system, check the video and press release after the break.
As you may know, crafting a katana is a delicate process that involves carefully constructing a razor-sharp high-carbon edge around a soft shock-absorbent core. One day though, smiths and forging fires could be replaced by electrode-wielding mad-scientists, with the technology to selectively harden and soften metal at will. At least that's what we envisioned when we read about Jörg Weißmüller's breakthrough research in the field of nanomaterials. The German scientist discovered that by placing precious metals in acid he could create tiny ducts through corrosion. Once those channels are flooded with a conductive liquid, electrical currents can be used to harden the material and, if you change your mind about the brittle results, the effect can easily be reversed to make it soft again. The tech could eventually lead to self-healing vehicle armor or scratch-resistant cellphones -- but, really, we just want to zap our way to a high-quality samurai sword. Physorg
