Changes in the Forecast for Pressure Sensors?

Welcome to All Sensors “Put the Pressure on Us” blog. This blog brings out pressure sensor aspects in a variety of applications inspired by headlines, consumer and industry requirements, market research, government activities, and you.

Changes in the Forecast for Pressure Sensors?

Similar to many other products, instead of growing in 2020, due to the impact of the COVID 19 pandemic, the pressure sensor market experienced a slight drop according to a recent market report. But recovery is in the forecast.  The global MEMS pressure sensor market is expected to grow at US$2.2 billion in 2026 having a 4% compound annual growth rate (CAGR) from 2019-2026 with the medical portion growing at the same CAGR.

In addition to their extensive use in automobiles, smartphones and industrial applications, the report acknowledges that the miniaturization of microelectromechanical systems (MEMS) pressure sensors has allowed their use in invasive medical applications like blood pressure monitoring. Also, “Other niche medical markets like catheters, inflating device monitoring for cardiovascular applications that are invasive and require high accuracy, low-cost sensors, are fully using the advantages of MEMS technologies and could foster broader use in the medical market.”

The report states that as a mature technology, MEMS pressure sensors currently dominate the low-pressure market segment – under 10 bars (145 psi) – with piezoresistive technology continuing to be the main MEMS technology for the next five years. All Sensors piezoresistive MEMS pressure sensors are poised to take advantage of broader use in medical applications, especially in the ultra-low pressure from 0.1-inch H2O (0.0036 psi) full scale up to the 25-inch H2O (0.9 psi) area.

Fracking and Pressure

Welcome to All Sensors “Put the Pressure on Us” blog. This blog brings out pressure sensor aspects in a variety of applications inspired by headlines, consumer and industry requirements, market research, government activities, and you.

Fracking and Pressure

In hydraulic fracturing or fracking, after a vertical shaft is dug from 1 to 2 miles deep in the earth to locate natural gas or oil, horizontal drilling occurs that can extend up to a mile from the vertical shaft. With the fracking well encased in steel and/or cement to prevent leakage into ground water, a fracking fluid is pumped down the well at pressures that can exceed 9,000 pounds per square inch (psi) or 62,050 kilopascals (kPA). This pressure can fracture the surrounding rock and create fissures and cracks for oil and gas flow. According to the U.S. Department of Energy (DOE), about 13,000 new wells are drilled every year.

With concerns over the consequences of fracking, many people’s blood pressure increases when the topic of fracking is discussed. Unlike, fracking pressures themselves, this pressure measurement is perfect for microelectromechanical systems (MEMS) pressure sensors.

Protecting MEMS Pressure Sensors with Parylene

Welcome to All Sensors “Put the Pressure on Us” blog. This blog brings out pressure sensor aspects in a variety of applications inspired by headlines, consumer and industry requirements, market research, government activities, and you.

Protecting MEMS Pressure Sensors with Parylene

Microelectromechanical systems (MEMS) pressure sensors provide accurate measurements for many applications. However, the top side of the piezoresistive MEMS pressure sensor die that has the sensing elements and potentially other circuitry cannot survive exposure to many common items that need to have their pressure measured — including water. To isolate the top surface of the pressure sensor die and other exposed circuitry, parylene is often used as a protective coating. Applied by a vapor deposition polymerization process, the parylene allows pressure to be transmitted to the top side of the pressure sensor to make measurements without damaging or impacting the reliability of the circuitry. The conformal, thin-film coating provides a moisture, chemical and dielectric barrier to protect the sensor’s critical circuitry in medical, automotive and other applications.

In fact, parylene extends the applications that a specific sensor design can address and is part of the packaging expertise that a sensor company may provide. Parylene coating can be found on a wide variety of All Sensors’ products. Specifically, parylene coating is available in all miniature digital product families such as the miniature digital DLVR, DLHR and DLLR Series as well as the millivolt output MLV series and the miniature digital and analog ELVR series.

Pressure Sensors and the IoT

Welcome to All Sensors “Put the Pressure on Us” blog. This blog brings out pressure sensor aspects in a variety of applications inspired by headlines, consumer and industry requirements, market research, government activities, and you.

Pressure Sensors and the IoT

The recently published “The Internet of Things (IoT) Sensors Market” report states, “In an Internet of Things ecosystem, two things are very important, the Internet and physical devices like sensors and actuators.” Based on the importance of the sensors, the report projects that the IoT sensors market will reach US$ 23.82 Billion by 2024, at a CAGR of 34.1% between 2018 and 2024.

The analysis includes pressure, temperature, humidity, magnetometer, gyroscope, accelerometer, image and inertial sensors. Segmented into wired and wireless pieces, the IoT sensor market report analyzes Consumer, Commercial, and Industrial market segments.

All Sensors' MEMS Pressure Sensors

Microelectromechanical systems (MEMS) pressure sensors deliver the size, performance, power consumption and cost to satisfy many if not most of the IoT pressure sensing requirements. Based on the variety of measurements that they address, it should not surprise anyone that their data will be used in numerous monitoring and control applications – cloud based or otherwise.
