A millimeter-scale, wirelessly powered cardiac device

A team of engineers at Stanford has demonstrated the feasibility of a super-small, implantable cardiac device that gets its power not from batteries, but from radio waves transmitted from outside the body. The implanted device ...

Scientists put spotlight on marine power

A team of researchers from Israel and the United Kingdom has discovered that energy produced from the planet's oceans can increase twofold when novel methods for predicting wave power are used. Presented in the journal Renewable ...

Marine energy doubled by predicting wave power

The energy generated from our oceans could be doubled using new methods for predicting wave power. Research led by the University of Exeter, published (27 June) in the journal Renewable Energy, could pave the way for significant ...

Sea waves as renewable resource in new energy converter design

Sea waves are a renewable and inexhaustible resource found in abundance across the planet. But efficiently converting sea wave motion into electrical energy has been challenging, in part due to the difficulty of compensating ...
