EMCORE has introduced its Model 1790 1550 nm High-Power Laser Module for LiDAR and Optical Sensing. The 1790 was developed for use as a CW coherent optical source for next-generation FMCW LiDAR systems in autonomous vehicles and other optical sensing applications. A custom version of this product is being adopted by a major provider of […]
Sensor Tips
How can sensors ensure safety for extreme temperature requirements?
The medical device industry requires extreme high temperatures in autoclaves to disinfect reusable devices and tools. As we have been reminded of recently with announcement of COVID-19 antibiotics, medicines as well as bio-samples require low temperatures for preservation in storage and transportation. Both of these extremes require sensors to monitor and maintain the proper temperature […]
Pressure sensors combine two sensing elements
First Sensor has released its new LHD ULTRA series, with all sensor types now available as samples — the first of which have already been delivered to customers. The high-precision 2-in-1 differential pressure sensors combine two sensing elements with different pressure ranges in a single housing. The models in the series feature a 16-bit analog […]
What is exponential technology?
In his presentation at the COMSWORLD2020 virtual event, Janusz Bryzek of eXo Imaging, described many details to support his premise of the exponential acceleration of healthcare problems. According to Bryzek, the convergence of exponential technologies or ExTech is accelerating the availability of healthcare to all. Exponential technologies include different types of health sensors, big data, […]
What is a Molecular Property Spectrometer sensor?
To measure and classify a wide range of combustible gases, NevadaNano has integrated multiple, complementary chemical sensors on a single silicon chip called the Molecular Property Spectrometer or MPS sensor. The chip’s patented array of micro-cantilevers with integrated piezoelectric sensing elements provides electrical actuation and sensing of resonance frequency. Monitoring resonance is a highly sensitive […]
MEMS humidity/temperature sensor boasts long-term stability
Würth Elektronik has developed a micro-electro-mechanical system (MEMS) sensor only 2 x 2 x 0.9 mm in size. Thanks to its low energy requirement and its calibrated and temperature-compensated digital output, the sensor measures humidity and temperature with long-term stability. The WSEN-HIDS humidity sensor is based on advanced MEMS technology: A dielectric polymer absorbs or […]
What is anosmia?
One of the common symptoms of COVID-19 is loss of smell or anosmia. This is not uncommon for patients with viral upper respiratory infections. The good news is this is temporary in most cases. The bad news is this prevents the personal detection of odors associated with critical odors from gas leaks, smoke from fires […]
Creating cryogenic environments for electronics
This FAQ series has gone to extremes and looked at “electronics that operate in extreme heat” (up to 800°C) and “electronics that operate in extreme cold” at cryogenic temperatures. This third and final FAQ will consider the various methods available to create artificial cryogenic environments. The temperature where refrigerated temperatures end and cryogenic temperatures begin […]
Electronics that operate in cryogenic cold
The first part of this FAQ series looked at “electronics that operate in extreme heat” (up to 800°C). This FAQ delves into the opposite end of the temperature spectrum and heads toward absolute zero. There are several existing cryogenic electronics applications, including superconducting quantum interference devices (SQUIDs) for measuring extremely subtle magnetic fields, microwave preamplification, […]
Electronics that operate in extreme heat to 800°C
Extreme environments require electronic systems capable of surviving beyond the MIL-STD operating temperature range of -55°C to +125°C. This FAQ series will go to extremes and look at super hot electronics (up to 800°C) and cryogenic electronics. Part one of this series looks at electronics that operate in extreme heat. Part two will look at […]
