4-in-1 MEMS sensor measures gases, humidity, temperature and barometric pressure
Whether at home, in the office, or outdoors, we need to be confident that the air around us is clean and safe to breathe – COVID-19 has clearly highlighted the importance of air quality. Due to the particulates, gases, and even airborne viruses ubiquitously present in our modern environment, poor air quality has an increasingly […]
What are the results of the 2019 MEMS Industry Commercialization Report Card survey? Pt 2
Roger Grace Associates MEMS Industry Commercialization Report Card (Report Card) Study for 2019 showed its overall grade remaining at B-, which has been so since 2014. This consistency demonstrates the maturity of the MEMS industry. The standard deviation from 1998 to 2019 was 0.55. Conducted annually since its inception in 1998 by Roger Grace of […]
First Sensor launches new LHD ULTRA series
First Sensor has released its new LHD ULTRA series, with all sensor types now available as samples — the first of which have already been delivered to customers. The high-precision 2-in-1 differential pressure sensors combine two sensing elements with different pressure ranges in a single housing. The models in the series feature a 16-bit analog […]
What is exponential technology?
In his presentation at the COMSWORLD2020 virtual event, Janusz Bryzek of eXo Imaging, described many details to support his premise of the exponential acceleration of healthcare problems. According to Bryzek, the convergence of exponential technologies or ExTech is accelerating the availability of healthcare to all. Exponential technologies include different types of health sensors, big data, […]
What is a Molecular Property Spectrometer sensor?
To measure and classify a wide range of combustible gases, NevadaNano has integrated multiple, complementary chemical sensors on a single silicon chip called the Molecular Property Spectrometer or MPS sensor. The chip’s patented array of micro-cantilevers with integrated piezoelectric sensing elements provides electrical actuation and sensing of resonance frequency. Monitoring resonance is a highly sensitive […]
High-accuracy inclination sensor in robust stainless steel housing
The new high-accuracy inclination sensor positilt PTM29 in a compact, laser-welded stainless steel housing is suitable for extremely harsh environmental conditions. It can also be used in place of rotary sensors with many benefits. The MEMS-based inclination sensor positilt PTM29 measures inclination in the range of +/-180° with one axis and in the range of […]
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 results of the 2019 MEMS Industry Commercialization Report Card survey? Pt 1
Since microelectromechanical systems (MEMS) technology involves numerous sensors from pressure sensors to accelerometers, gyroscopes and more and actuators such as microvalves, micromotors, micromirrors and more as well as many new areas, there should be broad industry interest in the results of the 2019 report card. The MEMS Industry Commercialization Report Card is a survey of […]
What is the MEMS report card for 2019?
Input for the 21st Annual MEMS Industry Commercialization Report Card Study (for 2019) is currently being requested. Compiled by Roger Grace, President of Roger Grace Associates, the purpose of the Report Card is to provide microelectromechanical systems (MEMS) industry participants with an objective assessment of the critical success factors over time for MEMS and to […]
