Best Streaming Devices: Watch anything your heart desires

No matter what content you want to watch, these streaming devices have got you covered. (Nicolas J Leclercq via Unsplash/) In the past few years, streaming has gone from an alternate to television to the new definition of television. The concept of “network” TV is becoming more and more obsolete as binge-watching and subscriptions have […]

A polymer electrode gets an electrical boost for use in E-skin devices. — ScienceDaily

Scientists around the world are working to develop electronic skins that attach to the body and monitor vital signs. These E-skins need to be comfortable, breathable, and flexible for everyday use. Gold is typically used to fabricate the electrodes that conduct electric signals in these applications. But gold is expensive, involves a complicated manufacturing process, […]

Stretchable micro-supercapacitors to self-power wearable devices — ScienceDaily

A stretchable system that can harvest energy from human breathing and motion for use in wearable health-monitoring devices may be possible, according to an international team of researchers, led by Huanyu “Larry” Cheng, Dorothy Quiggle Career Development Professor in Penn State’s Department of Engineering Science and Mechanics. The research team, with members from Penn State […]

New control strategy dynamically changes transmitter currents for optimal wireless charging in moving devices, such as robots and electric cars — ScienceDaily

Wireless power transfer has proven to be quite useful in electronic devices such as medical implants and smartphones. In most cases, this is done by aligning or “coupling” two separate coils of wire (transmitter Tx and receiver Rx). The electrical current circulating in the Tx coil then creates a magnetic field that transfers energy to […]

Patterning method could pave the way for new fiber-based devices, smart textiles — ScienceDaily

Multimaterial fibers that integrate metal, glass and semiconductors could be useful for applications such as biomedicine, smart textiles and robotics. But because the fibers are composed of the same materials along their lengths, it is difficult to position functional elements, such as electrodes or sensors, at specific locations. Now, researchers reporting in ACS Central Science […]

New green materials could power smart devices using ambient light — ScienceDaily

We are increasingly using more smart devices like smartphones, smart speakers, and wearable health and wellness sensors in our homes, offices, and public buildings. However, the batteries they use can deplete quickly and contain toxic and rare environmentally damaging chemicals, so researchers are looking for better ways to power the devices. One way to power […]

‘Electronic skin’ promises cheap and recyclable alternative to wearable devices

Researchers at the University of Colorado Boulder are developing a wearable electronic device that’s “really wearable”–a stretchy and fully-recyclable circuit board that’s inspired by, and sticks onto, human skin. The team, led by Jianliang Xiao and Wei Zhang, describes its new “electronic skin” in a paper published today in the journal Science Advances. The device […]
