Coping with the application environment is one of the more complex issues that sensors must address. To survive in harsh environments, sensors manufacturers improve the ruggedness of their sensors in many different ways. Three recently announced products exemplify the differences. For dusty and wet environments, Sensata Technologies ACW4 single turn and TCW4 multi-turn absolute Hall […]
How does sensor packaging adapt for challenging applications?
At the device level, packaging for microelectromechanical (MEMS) sensors is often performed by an outsourced assembly and test (OSAT) company. The sensors could include accelerometers, gyroscopes, magnetometers and microphones as well as pressure, temperature, infrared, biomedical, chemical and gas sensors. The first level of chip packaging formats includes cavity land grid array (LGA), molded cavity […]
How can a core simplify pressure sensing applications?
At Sensors Expo 2018, Gary Winzeler, Vice President of Marketing & Sales for DunAn Sensing discussed the company’s new approach to specifying pressure sensors using a core approach. DunAn introduced their Ceramic Diaphragm Core (CDC) Core pressure transducer and the MEMS DURAsense Core (MDC) at Sensor Expo. Both allow pressure measurements to pumps, valves and […]
What new materials will create new sensors?
Materials with unusual properties are a starting point for creating new sensors. A company involved in products with complex material properties and electronics possibly has an edge over its rivals when it comes to discovering or creating new sensing technologies. For example, Continental, a tire maker and automotive electronics supplier recently used electrically conductive rubber […]
How have pressure sensors changed over the last few years?
At Sensors Expo 2017, Jim Brownell, sales manager for All Sensors, shows the progression of microelectromechanical system (MEMS) pressure sensing over the past 30+ years from his company’s perspective. Starting with the A or alpha package that was created in the early 1980s, a packaged element pressure sensor had two integral ports and six leads […]
What are common ways to protect a sensor from harmful exposure?
For a sensor, the amount of harmful exposure it receives from the environment and harmful constituents in the measuring process depends on what is being sensed and the environment itself. Different packaging is required to cope with and survive the specific situation. Two major considerations for protection are at the sensing element/transducer level or at […]
How can you get more than one measurement from a single sensing technology?
Getting more than one sensor measurement from a semiconductor sensor package that is perhaps 50% or more smaller than one commonly used a decade ago is no problem. Two and even all three of the accelerometer, gyroscope and magnetometer (AGM) sensors found in an inertial measurement unit (IMU) commonly found in a smart phone are […]
What are ingestible sensors?
A recent report, notes that “in the medical sector, ingestible sensors are used in capsule endoscopy, patient monitoring, and controlled drug delivery applications.” Furthermore, the report projects that the ingestible sensor market is expected to grow from USD 198.2 Million in 2015 to USD 678.2 Million by 2022, at a CAGR of 20.2% between 2016 […]
