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.

Route to flexible electronics made from exotic materials

Engineers have developed a technique to fabricate ultrathin semiconducting films made from a host of exotic materials other than silicon. To demonstrate their technique, the researchers fabricated flexible films made from gallium arsenide, gallium nitride, and lithium fluoride — materials that exhibit better performance than silicon but until now have been prohibitively expensive to produce in functional devices.

Perovskite-silicon tandem solar cells with highest power conversion

The Hong Kong Polytechnic University (PolyU) has successfully developed perovskite-silicon tandem solar cells with the world's highest power conversion efficiency of 25.5% .

Vibration energy the secret to self powered electronics

ncorporated directly into a cell phone housing, the team's nanogenerator could harvest and convert vibration energy from a surface, such as the passenger seat of a moving vehicle, into power for the phone.

Engineers show how to optimize carbon nanotube arrays for hot spots

Experimental evidence and computer simulations suggest how to grow structures with the best trade offs between three desired characteristics: strength, flexibility and the ability to dissipate heat.

Canadian Government invests in vehicles of the future

The Honourable Gary Goodyear, Minister of State for Science and Technology, announced last week six new projects supported by the Automotive Partnership Canada (APC) initiative at the University of Windsor.
