A self-driving robot that weighs about the same as a raisin only needs surrounding light or radio waves to run indefinitely.

Nanoscale "tattoos" that could one day track the health of individual cells could provide early warnings for health problems.

A new surgical patch can seal wounds in the abdomen and send warning of potential leaks.

A new knitted fabric that senses contact and pressure could help robots to better interact with humans, researchers report.

An electronic tattoo that attaches to the chest and has a battery the size of a penny could provide continuous heart monitoring.

A 3D-​printed insole with integrated sensors will allow real-time measurement of the pressure of the sole of the foot right in a shoe.

A new sensor can be drawn with a pencil on treated paper. It could track health issues or even tell you when baby needs changing.

New sensors could lead to virus-detecting drones or even clothes that help diagnose diseases like breast cancer, researchers say.

A new two-dimensional material could help you take super-sharp photos with your phone, even in low light, researchers say.
