![]() Nano-biosupercapacitors enable autarkic sensor operation in blood Today's smallest energy storage devices for in-vivo applications are larger than 3mm cubed and lack the ability to continuously drive the complex functions of smart dust electronic and microrobotic systems. Smaller than a speck of a dust but with a similar voltage to a AAA battery, the groundbreaking energy storage device is not only safe for use in the human body, but actually makes use of key ingredients in the blood to supercharge its performance. Imagine the impact on cancer and the countless diseases that we could tackle with this technology.ĭust-sized supercapacitor packs the same voltage as a AAA battery By combining miniaturized electronics with some origami-inspired fabrication, scientists in Germany have developed what they say is the smallest microsupercapacitor in existence. One use could be having a micromachine measure blood pH for the presence of tumors. And, it uses the chemical reactions inside cells to recharge. It kept seventy percent of its charge for sixteen hours in blood. Tests show they can continue to store energy in saline, blood or plasma. They can provide a voltage equal to a triple-A battery, enough to power most uses within the human body. These materials are placed on a wafer surface that when high tension is applied, folds up origami-like into a nano-biosupercapacitor. This biosupercapacitor uses a stack of polymers with materials that can store electric current. A capacitor allows for electrical currents to be smoothed out so that a machine can run without power interruptions. ![]() German researchers now have one three thousand times smaller, the size of a pepper grain. But they've been too large at the size of an unpopped corn kernel. To make that possible, we need biosupercapacitors as an energy source. But current devices are simple, without power or many moving parts, so the goal is to make microrobotic systems that can work deep in the body. We already have them for detecting blood sugar and dispensing insulin. ![]() ![]() I was talking with a teenager recently and he already accepts that micromachine implants will be normal in the near future and he's right. ![]()
