Engineers harvest heart's energy to power life-saving devices

The heart’s motion is so powerful that it can recharge life-saving devices, according to new research. Using a dime-sized invention, the heart’s energy can be harnessed to power implantable devices, according to the study. Creating an energy source within the body could save millions of people who rely on pacemakers and other implantable devices from

Engineers create a robot that can 'imagine' itself

Engineers have created a robot that learns what it is, with zero prior knowledge of physics, geometry, or motor dynamics. Initially the robot has no clue what its shape is. After a brief period of ‘babbling,’ and within about a day of intensive computing, the robot creates a self-simulation, which it can then use to

Static electricity could charge our electronics

Static electricity is one of the most common, yet poorly understand, forms of power generation. A new study suggests the cause of this hair-raising phenomenon is tiny structural changes that occur at the surface of materials when they come into contact with each other. The finding could someday help technology companies create more sustainable and

The first tendril-like soft robot able to climb

Researchers have made the first soft robot mimicking plant tendrils: it is able to curl and climb, using the same physical principles determining water transport in plants. In the future this tendril-like soft robot could inspire the development of wearable devices, such as soft braces, able to actively morph their shape. Source link
