When should passive or active RFID be used?
The main difference between passive and active radio-frequency identification (RFID) tags is the absence (passive) or presence (active) of an internal power source. Because of these primary differences, there are several secondary differences. Understanding these differences is the key to properly selecting the most appropriate RFID system for a specific application. Passive RFID Since they […]
How can sensors protect a diamond center vault?
In Belgium’s’ Antwerp Diamond District, eighty percent of the world’s rough diamonds passed through a three-square-block area. The Diamond Squad, the world’s only specialized diamond police, provided 24-hour police surveillance and 63 video cameras monitored the district. In this area, the Antwerp Diamond Center vault was thought to be impenetrable. In addition to having a […]
Tiny, medical sensors feature large measurement range, accuracy, resistance to environmental effects
NewTek medical sensors withstand the effects of autoclave cycles used to sterilize medical equipment prior to surgical procedures or other medical uses. According to the Centers for Disease Control, steam sterilization, as accomplished in an autoclave, is the most widely used and dependable method of sanitizing critical medical equipment as a part of infection control. […]
An introduction to pressure sensors
As crucial devices in a wide range of industries and applications, pressure sensors are used to measure the pressure of gases or liquids and can be found in everything from medical equipment and automotive systems to HVAC units and more. While the basic principle of pressure sensors is straightforward (P=F/A), their simplicity ends there. Not […]
How can sensors save energy and improve sensor node battery life?
In a battery-powered, wireless sensing node, the biggest energy consumer typically is the RF transmitter. The transceiver should have extremely low power in active, wait and even sleep modes. A one-second snapshot of the current consumption in the various portions of the transmission cycle shows the current draw of 15 mA for the 7.5-ms receive […]
32-channel ultrasound transmitter features 5-level output capacity
STMicroelectronics has expanded its family of advanced ultrasound transmitters by adding a 32-channel variant with high output current for portable applications. The new transmitter, STHVUP32, provides ±800mA aimed at portable systems that demand extra drive capability for a coaxial cable-mounted probe. Joining the portfolio alongside the 64-channel STHVUP64, the new 32-channel version contains similar features to […]

This high-performance ultra-compact module, featuring a custom IC with an embedded temperature sensor, RTC functions, and integrated quartz crystal resonator, sets new standards […]
How do sensors impact ATMs?
It’s well known that automobiles and smartphones have several sensors to improve today’s capabilities over those of previous generations. However, they are not the only products that impact consumers’ lives to do so. For example, automated teller machines (ATMs) have a surprising number and different types of sensors to perform a variety of functions. Even […]
New ultra-low power digital microphone; half the consumption, identical performance
For the third consecutive year, Infineon Technologies AG has successfully defended its market-leading position as MEMS microphone supplier. Moreover, Infineon’s market share rose to a staggering 45 percent as bare die microphone manufacturer in 2021 [1], according to recent research published by technology expert Omdia. This positive development is due to Infineon’s long-term experience in MEMS […]
