Noise Analysis in Precision Analog Designs

There are articles explaining component-level noise analysis for amplifiers or for analog-to-digital converters (ADCs), but very few that explain how to budget noise or analyze noise from the system level. This paper reviews the basics of noise analysis in precision designs, relates those calculations to system-level specifications such as sensitivity, dynamic range, and resolution, and answers some of the big questions about low-noise design.

Cheaper, Simpler Nanomaterial for Wearable Devices

An international team of researchers from the University of Illinois at Chicago and Korea University say that they have developed an ultrathin film that is both transparent and highly conductive to electric current, while also being cheaper and simpler to produce than current materials.

Wearable System to Predict, Prevent Asthma Attacks

A team of engineers at North Carolina State University has developed an integrated, wearable system called the Health and Environmental Tracker (HET), that, they say, can monitor a user’s environment, heart rate, and other variables to predict and prevent asthma attacks. They plan to begin testing the system on a larger subject population this summer.

Diabetes Technology Society Develops Cybersecurity Standard for Devices

The Diabetes Technology Society recently announced its new cybersecurity standard for interconnected diabetes devices called DTSec. The standard specifies performance requirements utilizing the ISO/IEC 15408 framework used to define security requirements on “smart” medical devices. DTSec is initially targeted for networked devices, such as continuous glucose monitors and wireless insulin pumps, but, the group says there is nothing inherent in it to preclude its application to any other medical product or component.

3D Printing Metals Suspended in Midair

A team of engineers at Harvard’s Wyss Institute for Biologically Inspired Engineering and John A. Paulson School of Engineering and Applied Sciences (SEAS) say that a new form of 3D printing and laser annealing of conductive metallic inks without supports could lead to customized electronic and biomedical devices.

Edible Supercapacitors Could Replace Endoscopies

Engineers at Arizona State University (ASU), Tempe, have created an edible supercapacitor that, they say, can wipe out E. coli or power a camera from inside the body. Using edible foodstuffs like activated charcoal, gold leaf, seaweed, egg white, cheese, gelatin, and barbecue sauce, which can store and conduct electricity, and sandwiching them together, the researchers created supercapacitors that can store electrical energy temporarily.
