Nokia launches smartphone you can fix yourself, jumping on ‘right to repair’ trend

Posted by in categories: mobile phones, sustainability

Armed with tools and repair guides from hardware repair advocacy firm iFixit, a user can remove and replace the phone’s back cover, battery, screen and charging port.

Adam Ferguson, head of product marketing at HMD Global, said that this process would cost on average 30% less than replacing an old phone with a new one.

Smartphone companies are increasingly working to make phones last for longer amid pressure from regulators to make electronics devices more sustainable.

Robots now have the sense of touch after electronic skin is created

Posted by in categories: innovation, robotics/AI

A team of scientists has developed electronic skin that could pave the way for soft, flexible robotic devices to assist with surgical procedures or aid people’s mobility.

The creation of stretchable e-skin by Edinburgh researchers gives soft robots for the first time a level of physical self-awareness similar to that of people and animals.

The technology could aid breakthroughs in soft robotics by enabling devices to detect precisely their movement in the most sensitive of surroundings, experts say.
