Anyone who’s spent significant amounts of time salvaging old electronics has probably wished there were a way to take apart a circuit board without desoldering it. [Zeyu Yan] et al seem to have had ...

A new type of self-healing and reconfigurable circuit board can withstand heavy damage and still work effectively, scientists say. It can even be completely recycled once it reaches the end of its ...

Strings of liquid-metal beads embedded in a polymer have been used to create highly stretchable printed circuit boards. Stretchable electronics are being developed for applications such as wearable ...

Tossed circuit boards are about 20% copper, a much larger fraction than the roughly half a percent in copper ore mined from the ground. That percentage, plus the growing mounds of global electronic ...

Electronics such as Bluetooth speakers can be 3D-printed from a material that dissolves in water within hours. That allows designers to rapidly create prototypes, enables easier recycling of the ...
