Reaching silicon-based NEMS performances with 3D printed nanomechanical resonators

Abstract: "The extreme miniaturization in NEMS resonators offers the possibility to reach an unprecedented resolution in high-performance mass sensing. These very low limits of detection are related to the combination of two factors: a small resonator mass and a high quality factor. The main drawback of NEMS is represented by the highly complex, multi-steps, and expensive fabrication process... » read more

Power/Performance Bits: Oct. 2

Photonic sensor Researchers at Washington University in St. Louis devised a way to record environmental data using a wireless photonic sensor resonator with a whispering-gallery-mode (WGM) architecture capable of resonating at light frequencies and also at vibrational or mechanical frequencies. Optical sensors are not affected by electromagnetic interference, a major benefit in noisy or har... » read more

Making Phones Better

Beneath a smartphone's slick packaging is some interesting, highly sophisticated technology that makes the user experience what it is today. Much of that experience relies on satisfying our ever growing desire for more data capacity for video, social media and the like. Providing that capacity relies on robust filtering to receive just your data stream amongst many nearby other streams. But tha... » read more

Fast Analysis Of Acoustic Resonators For The Rapidly Growing Premium RF Filter Market

Acoustic resonator filters have been used in cell phones since the early 2G wireless standard. Now, typical smart phones employ 30 or more filters as mobile carriers push to support more and more data bands as well as Wi-Fi, Bluetooth and GPS. Market pressure for these RF filters to be compact and inexpensive, yet meet the higher performance requirements of the 4G standards, has spurred great i... » read more
