Approaching Dissolvable Electronics for Implants
Posted in News, Electronic Components, Electronics, Implants & Prosthetics, Patient Monitoring on Monday, 02 May 2016
Scientists at the College of Information Science and Electronic Engineering in China are working diligently to create tiny electronic sensors and devices that can be implanted in the body and then dissolve seemingly without a trace. They have tested several biodegradable materials, including DNA, proteins, and metals, for making transient electronics. Edging closer, their newest dissolvable device is composed of egg proteins, magnesium, and tungsten.

High-Bandwidth, Wide Field-of-View, Ultra-Sensitive, Radiation-Hardened, Short-Wave Infrared (SWIR) Receiver
Posted in Briefs, Electronics on Saturday, 30 April 2016
Goddard Space Flight Center, Greenbelt, Maryland Every LiDAR design faces the classic balancing act of signal versus noise. In order to maximize the range of a LiDAR, a receiver must amplify fractions of a micro-amp of photo current into a usable range for signal processing to occur, but without adding significant amounts of noise. Additionally, LiDAR receiver designs must exhibit very wide dynamic ranges because of the uncertainty in return signal amplitude. Meeting all these requirements in a small size, weight, and power form factor while keeping costs low is a major challenge.

Magnetometer for Vectorized Field Sensing via Zero-Field, Spin-Dependent Recombination in Silicon Carbide Microelectronics
Posted in Briefs, Electronics on Saturday, 30 April 2016
This self-calibrating, solid-state-based magnetometer is intended for miniaturized applications in high-temperature and high-radiation environments. NASA’s Jet Propulsion Laboratory, Pasadena, California The proposed technology involves the sensitive detection of magnetic fields using the zero-field, spin-dependent recombination (SDR) phenomenon that naturally arises from atomic-scale, deep-level defects intrinsic to silicon carbide (SiC) microelectronics. The SDR phenomenon enables the fabrication of SiC-based magnetic field sensing diodes that are ideal for the development of miniaturized and purely electrical-based magnetometers.

Ethernet-to-HRDL Conversion Design
Posted in Briefs, Electronics on Saturday, 30 April 2016
Dual Ethernet inputs are multiplexed into a single HRDL stream to accommodate Ethernet-based ISS instruments. Goddard Space Flight Center, Greenbelt, Maryland The International Space Station (ISS) uses a fiber optic High Rate Data Link (HRDL) standard for transferring data. ISS experiments, however, may prefer an Ethernet interface. This design allows ISS instruments to keep their Ethernet interface by converting the Ethernet data format into a format compatible with the ISS. The Express Logistics Carrier (ELC) incorporated this design on the ISS in 2010. The design was described with VHDL code. It has been implemented with an Actel RTAX Field Programmable Gate Array (FPGA). This FPGA is part of the Express Logics Carrier (ELC) onboard the ISS.
