Developing Effective Design Strategies For Today’s Wearable Devices: Security
By Mentor, a Siemens Business - 03 Mar, 2016 - Comments: 0

We love our wearables, but wearable devices connected to public networks supporting bi-directional data flow make our devices...and us...highly susceptible to attack. Security can no longer be thought of as an “afterthought” to embedded system design; development teams must design in security methods and adopt a security development lifecycle approach that meets the appropriate security lev... » read more

Inside Neuromorphic Computing
By Mark LaPedus - 25 Jan, 2016 - Comments: 2

Semiconductor Engineering sat down to talk about neuromorphic technology with Guy Paillet, chief executive of General Vision. The fabless IC design house is a pioneer and supplier of neuromorphic chips. What follows are excerpts of that conversation. SE: In 1993, you invented and co-patented a neural networking chip with IBM. Then, you joined General Vision in 1999. Briefly tell us about Gen... » read more

Wearing your batteries In spite of the progress in wearable devices, one challenge remaining is providing less obtrusive and cumbersome power sources. To tackle the problem, researchers at Case Western Reserve University developed flexible wire-shaped microsupercapacitors that can be woven into a jacket, shirt or dress. "The area of clothing is fixed, so to generate the power density need... » read more

GaN building blocks A team of engineers from Cornell University, the University of Notre Dame, and the semiconductor company IQE created gallium nitride (GaN) power diodes capable of serving as the building blocks for future GaN power switches. In spite of having many desirable features as a material, GaN is notorious for its defects and reliability issues. So the team zeroed in on device... » read more

Hiding wires from the sun There's a problem with most solar cells: the electricity-carrying metal wire grid on top prevents sunlight from reaching the semiconductor below. A team from Stanford University tackled this problem, discovering a way to hide the reflective upper contact and funnel light directly to the semiconductor below. For the study, the researchers placed a 16-nanometer-thi... » read more

Think In Blocks

It always seems to come back to LEGOs, doesn’t it? Earlier this year I wrote about Google Project Ara, the so-called “LEGO” smart phone architecture unveiled in April. Project Ara uses the MIPI Alliance UniPro and M-PHY protocols as the backbone for a modular electronics architecture inside a smart phone “endoskeleton.” Using electro-permanent magnets (they don’t need a perma... » read more

Wearable Devices: A Limitless Future

Today, there are many wearable systems across industries including medical and health care, safety, smartwatches, smart goggles and glasses, smart shoes and clothing — even smart pet trackers! So why is there such a proliferation of devices, even though many of these portable/embedded devices have been around for decades? There are a few key technical trends enabling these devices. F... » read more

Developing Effective Design Strategies For Today’s Wearable Devices

While many new fitness bands, smartwatches, and other wearable devices have entered the market, most have under-whelmed prospects and users. It is quite clear the wearable industry is in its infancy and fraught with growing pains. Software developers, embedded systems architects and engineers must take heed in the early miscalculations of these devices (whether it’s functionality, utility, pr... » read more

Stretchy metal Washington State University researchers stretched metal films used in flexible electronics to twice their size without breaking. The discovery could lead to dramatic improvements and addresses one of the biggest challenges in flexible electronics, an industry still in its infancy with applications such as bendable batteries, robotic skins, wearable monitoring devices and se... » read more
