Human blood liquid memristors could be the key to cyborg interfaces

Eurekalert – Simplifying cyborg circuitry using human blood

Could electronic components made from human blood be the key to creating cyborg interfaces? Circuitry that links 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 biological components. Writing in the International Journal of Medical Engineering and Informatics, a team in India describes how a “memristor” can be made using human blood.

They constructed the laboratory-based biological memristor using a 10 ml test tube filled with human blood held at 37 Celsius into which two electrodes are inserted; appropriate measuring instrumentation was attached. The experimental memristor shows that resistance varies with applied voltage polarity and magnitude and this memory effect is sustained for at least five minutes in the device.

Having demonstrated memristor behavior in blood, the next step was to test that the same behavior would be observed in a device through which blood is flowing. This step was also successful. The next stage will be to develop a micro-channel version of the flow memristor device and to integrate several to carry out particular logic functions. This research is still a long way from an electronic to biological interface, but bodes well for the development of such devices in the future

Human blood liquid memristor

An experimental study on a physical model of memristor made from human blood (as material of resistor) is presented. The model manifests memristor characteristics as defined by Professor Leon Chua (1971), Strukov (2008) and William (2008). Speculative potential applications in human healthcare science and electronic memory circuit science/technology is envisaged.
