Power/Performance Bits: April 14


Elastic energy harvesting Researchers from the Korea Advanced Institute of Science and Technology (KAIST) and Seoul National University collaborated to develop a hyper-stretchable elastic-composite energy harvesting device. Their stretchable piezoelectric generator can harvest mechanical energy to produce a ~4V power output with around 250% elasticity and a durability over 104 cycles. The... » read more

New Challenges For Wearables


The earliest recorded mention of a wristwatch dates back to the late 1500s, but it really began gaining adherents in Great Britain’s Boer War campaign as a way of synchronizing military actions beyond the line of sight. Strapping a pocket watch to a horse or a camel simply didn’t work, and pulling it out of a jacket pocket was not only inconvenient, it was dangerous. Advertised as a “c... » read more

Energy Harvesting Makes Progress


The dream of a self-powered device has been around for a long time—thousands of years, in fact. The first windmills and waterwheels date back to ancient Greece and the beginning of recorded history. Self-winding timepieces date back to the late 1700s. The Foucault pendulum has been in motion in Paris, minus some brief hiatuses, since 1851. And it's been 144 years since two French physicists d... » read more

Move Over AI, Here Comes AmI


Artificial Intelligence has received lots of attention, but a new term called Ambient Intelligence (AmI) is emerging as a cornerstone of the [getkc id="76" comment="Internet of Things"]. The term is a relatively unknown, but not all that new. AmI dates back 16 years—just a few years after the Internet saw its first widespread commercial adoption—when the concept first emerged as a collec... » read more

Boosting Battery Life In IoT Devices


Honing in on a sweet spot for an IoT application can be very tricky, especially when it comes to a battery-based one. However, the Paper Battery Co. is working to do just that. With technology based on a, you guessed it, a paper battery, the company’s CEO Shreefal Mehta said the company believes the concept of having power that was able to go into spaces that today the batteries and rigid ... » read more

The Missing Link


What continues to fascinate me about the IoT opportunity is the explosion of creative ideas that are being imagined and developed to enable the next big thing. When I imagine the kind of connectivity and control that will need to happen between the Internet and ‘smart’ devices, these things obviously must be very inexpensive, super small, with the ability to harvest their own energy. ... » read more

Power/Performance Bits: Sept. 9


Harvesting power from air A centuries-old clock built for a king is the inspiration for a group of University of Washington computer scientists and electrical engineers who hope to harvest power from the air. The clock, powered by changes in temperature and atmospheric pressure, was invented in the early 17th century by a Dutch builder. Three centuries later, Swiss engineer Jean Leon Reutter b... » read more

Power/Performance Bits: July 15


Improving battery performance with sand Researchers at the University of California, Riverside’s Bourns College of Engineering have created a lithium ion battery that outperforms the current industry standard by three times using sand as the key material. The researchers, who said this is a low cost, non-toxic, environmentally-friendly way to produce high performance lithium ion battery a... » read more

IP And FinFETs At Advanced Nodes


Semiconductor Engineering sat down to discuss IP and finFETs at advanced nodes with Bernard Murphy, CTO of Atrenta; Warren Savage, president and CEO of IPextreme; Aveek Sarkar, vice president of engineering and product support at Ansys-Apache; Randy Smith, vice president of marketing at Sonics. What follows are excerpts of that conversation. SE: As we push into the next nodes, we’ve got a ... » read more

Micro-Power Energy Harvesting


Since the beginning of the human race’s self-awareness, people have strived to harness the planet’s free energy sources; wind, solar, thermal and hydro. On a macro scale, man’s dreams have come to fruition. The next frontier is capturing energy on a micro scale. On the macro front, there are massive corridors of energy powered by wind and solar developments, which generate megawatts of... » read more
