If the notion of next-generation electronic components made from actual human blood cells chills you, you may not want to read on. But if you are interested in how future artificial limbs or eyes may be wired up to patients, then this new research will intrigue you.
Memristors are a type of electronic device that you may haven't heard about, since they were conceived theoretically a long time ago. But they're only now becoming plausible in manufacturing--the trick is to modify an electrical current depending on a "signal" in a similar way to a transistor does, only in the case of a memristor the way they behave depends on how they were last activated. They thus have a degree of "memory" that means they behave a little more like your own brain cells do, and this has hardware folk all excited about their potential computing power. A team of scientists in Gujarat has now succeeded in making memristors out of modified human blood cells.
