According to the proverb, “seeing is believing,” but hearing something before you can see it can be very important, too. The earliest humans heard and recognized the sounds of predators long before they could see them. If they could see them — it was probably too late to take evasive action. While sound has always […]

T5838 MEMS microphones preferred choice for edge AI applications
TDK Corporation announces that its low-power InvenSense T5838 and T5837 digital PDM microphones, part of the SmartSound™ family, have established themselves as the microphone of choice for low-power edge AI application processors that perform keyword detection due to its innovative Acoustic Activity Detect (AAD) feature that enables system power savings, thus prolonging battery life, and […]
How does sensing help in paranormal research?
Paranormal does not usually imply a scientifically sound phenomenon. However, when science is used to verify the observation, the situation changes. This is where a variety of sensors come into play. After all, it is called extra sensory perception (ESP). In the United States, a push in the scientific community to empirically study paranormal experiences […]
TMR magnetic sensor offers SNR with detectivity at ~ 5μT

The CT40x revolutionizes current sensing in today’s dynamic and demanding environments with unparalleled performance and exceptional accuracy addressing all contact and contactless current sensing applications. The CT40x is engineered to provide […]
Has integrated sensor and circuitry reached a new milestone?
Since the earliest days of microelectromechanical systems (MEMS) sensor products, the goal of easily combining the sensing structures made using MEMS processing with the required signal conditioning has driven many sensor R&D labs. If successful, the solution would make the resulting devices more useful in a broader range of applications. In the 1980s, the circuitry […]
How are sensors used in 3D bioprinting?
In general, three-dimensional (3D) printing or additive manufacturing is the construction of a three-dimensional object from a digital 3D model. With 3D bioprinting, the 3D constructs are living cells, biomaterials, bioactive components, and more. In the 21st Century, the generation and transplantation of several tissues, including multilayered skin, bone, vascular grafts, tracheal splints, heart tissue, […]
Z-axis TMR sensor replaces Hall-element sensor designs
Crocus Technology announced the release of the CT130, a 1-D linear TMR sensor that is sensitive in the Z axis. The CT130 is a revolutionary product that provides unparalleled temperature stability, high accuracy, and precision for position and current sensing applications. The CT130 from Crocus Technology is the world’s first true TMR sensor with Z-axis […]
How can sensors protect vulnerable areas? Pt 4
The U.S. Environmental Protection Agency (EPA) has ongoing efforts to address the unintended contamination and purposeful contamination of the nation’s water supplies. Sensing technologies are an integral part of the strategy. In 2023, the EPA proposed new limits to drinking water contamination from toxic “forever chemicals” or per fluoroalkyl and polyfluoroalkyl substances (PFAS). Used widely […]
How can sensors protect vulnerable areas? Pt 3
Today, advertisements for Camp Lejeune lawsuit settlements are frequently seen on cable and network TV. Another frequently cited water disaster occurred in Flint, Michigan. Detecting lead in drinking water On April 25, 2014, the City of Flint changed its water supply source from Lake Huron water (supplied by Detroit) to the Flint River. Subsequently, water […]
2D hall effect sensor is ASIL C-ready
TDK Corporation introduces the Micronas fast 2D Hall-effect position sensor family HAL 302x addressing the need for stray-field robust motor position sensing as well as ISO 26262 compliant developments in automotive and industrial applications. This new sensor family initially consists of two members, HAL 3020 and HAL 3021, and features differential and single-ended sine and […]
