Power/Performance Bits: Sept. 26


Long-range communication Researchers at the University of Washington developed devices that run on almost zero power can transmit data across distances of up to 2.8 kilometers. The long-range backscatter system, which uses reflected radio signals to transmit data at extremely low power, achieved reliable coverage throughout 4800-square-foot house, an office area covering 41 rooms and a one-acr... » read more

Power/Performance Bits: June 27


Superconducting nanowire memory cell Researchers at the University of Illinois at Urbana-Champaign and the State University of New York at Stony Brook developed a new nanoscale memory cell that provides stable memory at a smaller size than other proposed memory devices, and holds promise for successful integration with superconducting processors. The device comprises two superconducting nan... » read more

Power/Performance Bits: March 7


Supercapacitor plants Scientists at Linköping University in Sweden developed a method for transforming roses into supercapacitors that can be charged and discharged hundreds of times. The team created a solution that, when fed through the cut end of the stem, polymerizes inside the rose's vascular system with the plant's own biochemical response mechanism acting as catalyst, creating lon... » read more

The Real Value In Customizing Instructions


One element that distinguishes devices for the emerging IoT market from the mobile devices of the mature handheld market is power. Specifically, while the latter can accept a battery recharge cycle of days, the former demands years between battery recharge/replacement. Where the two devices resemble one another is their need for high performance. While embedded CPU cores have concentrated o... » read more

The Week In Review: Design/IoT


IP Cadence rolled out a fourth-generation audio/voice DSP core for 32-bit DTS-X audio/voice processing, using multi-channel object-based audio. The technology allows for more textured 3D sound, while simplifying the steps for creating sound channels. Chips NXP rolled out a one-chip solution for smart car access, which combines passive keyless entry, an RF transmitter and an immobilizer. Th... » read more
