Indian researchers may have brought the fictional man/machine one step closer to reality, devising innovative new electronic components -- made from human blood. They speculate that circuitry to link human tissues and nerve cells directly to an electronic device, such as a robotic limb or artificial eye, might one day be possible thanks to the development of these biological components
They constructed the biological memristor in a laboratory using a 10-milliliter test tube filled with human blood held at 98.6 Fahrenheit (37 Celsius) into which two electrodes are inserted; appropriate measuring instrumentation was attached. The experimental memristor shows that resistance varies as voltage sent through it changed. The device retained a specific level of resistance for at least five minutes -- the reason for the name "memory resistor."
Having demonstrated memristor behavior in blood, the next step was to test for the same behavior in a device through which blood is flowing -- which Kosta also managed to do.
He plans to develop a version of the device that combines several memristors to carry out a specific logic function.
