Wireless sensor nodes need to run on batteries for many years. SiTel Semiconductor and RTX Telecom are proposing a new ultra-low-energy extension to the existing DECT standard especially for this kind of application.
Allegro MicroSystems, Inc. introduces a user-programmable linear Hall-effect sensor IC with pulse width modulated output.
The integration of sensors and actuators into encapsulated multi-chip modules creates formidable challenges to characterizing and controlling process pressure. However, a new measurement method developed by Fraunhofer IZM shows that pressure-indicating sensor film can fully characterize the area pressure distribution on the cavity and on substrate surfaces within a mold cavity during encapsulation.

This product training module offers a succinct and informative presentation of Omron's MEMS flow sensor line-up, as well as their MEMS technology.
For humans, an unobserved fall can have very serious consequences. In some cases, the initial injury can become more traumatic if not treated within a short time. In other cases, an individual can suffer an accidental fall as the result of weakness or dizziness due to a diminished self-care and self-protective ability.
The current state of healthcare today in the US is one which focuses upon cost containment, while at the same time, providing the advancements of modern technology to an aging population. Finding effective treatment methods at affordable levels, while at the same time providing patients with high quality care is certainly a tightrope act many healthcare providers walk.
In Crossing the Chasm, Geoffrey A. Moore introduced the Technology Adoption Lifecycle. This curve highlights a chasm that exists between visionaries who are early adopters of technology and pragmatists who wait for proven technologies and products. For technologies to “cross the chasm” one key component are products with defined product specifications and system deployment guidelines.
Energy harvesting technology took center stage at this year’s Sensors Expo in Rosemont, IL. Whether the solution obtained its power from the sun, heat, vibration, wind, RF or magnetics, there was a device at the show to take advantage of many of these or other ambient conditions. Infinite Power Solutions’ THINERGY thin micro-energy cells (MECs), in capacities of .0 mAh and 0.4 mAh initially, are positioned as the world’s most powerful batteries for their size and outperform all other micro-batteries.
The effects of man-made climate change, once seen as a problem for future generations, is now viewed as an immediate threat, have led to significant technological investments to build a more sustainable future. From measuring the decline of snow packs in Antarctica and the North Pole, to measuring the impact of man-made dams on salmon migration patterns, to the development of systems that better predict natural disasters, remote wireless sensors are playing an increasingly critical role in advanced scientific technology.
In carrier networks, the fiber plant uses Dense Wavelength-Division Multiplexing (DWDM) technology to combine more than 80 channels to transport the Internet traffic. Today, these DWDM channels are dominated by 10Gb/s line rate and channels are separated by a 50GHz spacing. With limited fiber, these 10G channels are the constraints at the critical fiber route now.
Let's start with a tough question: What is the difference between TPMS system and PKE system? Nothing! A TPMS system is placed inside the wheel and composed of a sensing device that measures temperature and pressure. When appropriate, for example before starting the engine, the car requests a measurement through a wireless link. If a pressure default occurs in one of the wheels, the car warns the driver through a signal on the dashboard. In PKE applications, the user carries a key fob device which contains an encoded identifier (ID). When the driver enters their car, the car requests the key fob ID through the wireless link. If the ID matches the ID stored by the car,
Automated Storage and Retrieval Systems (ASRS) are at the heart of any fully automated warehousing system. As in all automated solutions, users demand nearly perfect, (i.e., 100%) availability and exceptionally fast operation at the lowest possible price point. While the raw speed of an ASRS along each axis of motion is limited by the selected drives’ components, modern sensor technology
For the last half-century, sensors based on the Hall effect have provided a low-cost, solid-state option for sensing any object that incorporates a magnetic field. Hall effect sensors are based on the discovery by Dr. Edwin H. Hall in 1879. He found that a thin conductive material, placed in a magnetic field, formed a difference in potential (voltage) at the opposite edges that was
Piezoelectric ceramic components composed of Lead Zirconate Titanates (PZT) have enabled many recent technological innovations in the automobile industry. PZT components can be found throughout many state-of-the-art vehicles, enhancing safety, performance, energy-efficiency and comfort. For example, you will find PZT sensors under the hood detecting engine knocking, PZT transducers in the gas tank measuring the fuel level, PZT actuators operating valves
When considering a relative humidity sensor for one’s application, the selection process involves a series of choices to meet application requirements and key parameters while, at the same time, insuring that the product selected delivers the lowest total cost solution. Despite the diversity in humidity sensor applications and specifications, the desire
