Soft Robot Actuators Heal Themselves

Repeated activity wears on soft robotic actuators, but these machines' moving parts need to be reliable and easily fixed. Now a team of researchers has a biosynthetic polymer, patterned after squid ring teeth, that is self-healing and biodegradable, creating a material not only good for actuators, but also for hazmat suits and other applications where tiny holes could cause a danger.

In East Africa, a Race to Outsmart Locusts with Drones and Data

While the eyes of the world are on the novel coronavirus, East Africa continues to struggle with another crisis of biblical proportions: growing swarms of ravenous locusts. Both crises are extraordinary in scale, and both foes multiply so quickly that governments are struggling to contain them.

Scientists Tap Unused Energy Source to Power Smart Sensor Networks

The electricity that lights our homes and powers our appliances also creates small magnetic fields that are present all around us. Scientists have developed a new mechanism capable of harvesting this wasted magnetic field energy and converting it into enough electricity to power next-generation sensor networks for smart buildings and factories.

Design Approach May Help Fix Bias in Artificial Intelligence

Bias in artificial intelligence and machine learning programs is well established. Researchers are now proposing that software developers incorporate the concept of "feminist design thinking" into their development process as a way of improving equity - particularly in the development of software used in the hiring process.

Engineers Mix and Match Materials to Make New Stretchy Electronics

At the heart of any electronic device is a cold, hard computer chip, covered in a miniature city of transistors and other semiconducting elements. Because computer chips are rigid, the electronic devices that they power, such as our smartphones, laptops, watches, and televisions, are similarly inflexible. Now a process developed by engineers may be the key to manufacturing flexible electronics with multiple functionalities in a cost-effective way.

AI Learns to Design

Big design problems require creative and exploratory decision making, a skill in which humans excel. When engineers use artificial intelligence, they have traditionally applied it to a problem within a defined set of rules rather than having it generally follow human strategies to create something new.

Machine Learning Algorithms Help Predict Traffic Headaches

Urban traffic roughly follows a periodic pattern associated with the typical "9 to 5" work schedule. However, when an accident happens, traffic patterns are disrupted. Designing accurate traffic flow models, for use during accidents, is a major challenge for traffic engineers, who must adapt to unforeseen traffic scenarios in real time.
