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 […]
What is photoacoustic spectroscopy (PAS)?
Identified in the 19th century, the photoacoustic effect allows the conversion of light into sound and has been employed in devices such as non-dispersive infrared absorption spectroscopy (NDIR), which was the first commercially available device to detect gases using this effect. Modulating the light intensity produces a periodic pressure variation, which is measured with a […]
What are the evolving semiconductor technologies for modern telehealth applications?
by Sanjay Pithadia, System Engineer, Medical Sector, System Engineering, and Marketing atTexas Instruments Health care continues to evolve toward self-treatment and away from in-person appointments. In addition to helping reduce physical contact, new technologies have given the general population unprecedented access to health care tools for self-monitoring and remote treatments. Whether it’s providing mobility to […]
3D depth sensor is based on ToF technology
Gaming, virtual e-Commerce, 3D online education: Augmented Reality (AR) applications with three-dimensional depth sensors link the real with the digital world and are strongly demanded. Infineon Technologies AG and pmdtechnologies developed a 3D depth sensor based on the Time of Flight (ToF)-technology which outperforms other solutions in the market and aims for target applications that offer […]
How can a load cell force sensor be used in increasingly smaller end products?
A smaller form factor is frequently on the must have list for many next generation products. However, compromising performance is usually not an acceptable tradeoff. This is especially true in medical products such as force sensors where both precision and miniaturization are required. For example, vascular clamps are used to reduce the flow of blood […]
