Telecare Challenges: Secure, Reliable, Lower Power


The adoption of telecare using a variety of connected digital devices is opening the door to much more rapid response to medical emergencies, as well as more consistent monitoring, but it also is adding new challenges involving connectivity, security, and power consumption. Telecare has been on the horizon for the better part of two decades, but it really began ramping with improvements in s... » read more

MRAM speed Researchers at ETH Zurich and Imec investigated exactly how quickly magnetoresistive RAM (MRAM) can store data. In the team's MRAM, electrons with opposite spin directions are spatially separated by the spin-orbit interaction, creating an effective magnetic field that can be used to invert the direction of magnetization of a tiny metal dot. "We know from earlier experiments, i... » read more

Tandem solar reaches 25.2% efficiency In the push for ever-more efficient solar panels, researchers are turning to tandem, or double-junction, photovoltaics. Tandem solar panels use two different types of solar cell capable of absorbing different wavelengths of light stacked on top of each other to maximize the conversion of light rays into electrical power. Recently, two groups have reache... » read more
