For example, some liquibots could detect different types of gas in the environment, while others react to specific types of chemicals. The liquibots go back and forth, like the pendulum of a clock, and can run continuously as long as there is 'food' in the system.ĭepending on their formulation, an array of liquibots could carry out different tasks simultaneously. This triggers a reaction that generates oxygen bubbles, which like little balloons lift the liquibot up to the surface.Īnother reaction pulls the liquibots to the rim of a container, where they 'land' and offload their cargo. Through a series of experiments in Berkeley Lab's Materials Sciences Division, Russell and first author Ganhua Xie, a former postdoctoral researcher at Berkeley Lab who is now a professor at Hunan University in China, learned that 'feeding' the liquibots salt makes the liquibots heavier or denser than the liquid solution surrounding them.Īdditional experiments by co-investigators Paul Ashby and Brett Helms at Berkeley Lab's Molecular Foundry revealed how the liquibots transport chemicals back and forth.īecause they are denser than the solution, the liquibots - which look like little open sacks, and are just 2 millimeters in diameter - cluster in the middle of the solution where they fill up with select chemicals. In contrast, 'we don't have to provide electrical energy because our liquibots get their power or 'food' chemically from the surrounding media,' Russell explained. Russell said that the technology significantly advances a family of robotic devices called 'liquibots.' In previous studies, other researchers demonstrated liquibots that autonomously perform a task, but just once and some liquibots can perform a task continuously, but need electricity to keep on running. 'We have broken a barrier in designing a liquid robotic system that can operate autonomously by using chemistry to control an object's buoyancy,' said senior author Tom Russell, a visiting faculty scientist and professor of polymer science and engineering from the University of Massachusetts Amherst who leads the Adaptive Interfacial Assemblies Towards Structuring Liquids program in Berkeley Lab's Materials Sciences Division. It has potential as an automated chemical synthesis or drug delivery system for pharmaceuticals. The technology is the first self-powered, aqueous robot that runs continuously without electricity. Now, as reported last week in the journal Nature Chemistry, scientists at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of Massachusetts Amherst have demonstrated just that - through 'water-walking' liquid robots that, like tiny submarines, dive below water to retrieve precious chemicals, and then surface to deliver chemicals 'ashore' again and again. For many years, scientists have wanted to make a robot that can work autonomously and continuously, without electrical input. Yet even the most sophisticated robot can run out of juice. There are a number of studies that show taking a 15-minute break every 90 minutes will help both your energy levels and productivity.But before a robot can get to work, it needs energy - typically from electricity or a battery. Not only is this hard on my eyes, but it’s going to kill my energy levels in the long run. Sometimes I find myself on a real work bender and realize that I have been on the computer for hours without taking a break. org states that a healthy, balanced diet that's high in fiber and low in added sugars could help you to fall asleep faster, and give you as much as two extra hours of sleep per night. Eating late will also keep you up at night because of the extra energy it uses to digest your food. A study from Harvard stated that the circadian rhythms of people who eat a lot at lunch typically show a more pronounced afternoon slump. Instead of eating a burger and fries, eat a salad with quinoa or some other equivalent of a small but robust meal. Eating right goes hand-in-hand with regular exercise.

Exercise also helps you maintain better sleeping habits, and a study from the Sleep Foundation found that adults with insomnia fell asleep more quickly, slept slightly longer and had better sleep quality than before they began exercising. By working out, your body and your brain will have kickstarted into high gear so you can come into work feeling fresh and inspired. An article on WebMD states that researches say expending energy by engaging in regular exercise may pay off with increased energy in the long run.

While it may seem like working your body out when you first wake up will cause you to crash even harder, the opposite is true.
