Of course. However, the conversion process to get useful electricity certainly is not. Also, several design considerations must be taken into account to ensure a system’s success. This includes thinking differently about power consumption. With all of the wireless communications applications expanding in consumer, commercial and industrial applications, the power must be achieved without connecting […]
What is chromatography?
According to “Chromatography Composition Measurement,” in The Measurement, Instrumentation, and Sensors Handbook, chromatography is a technique for separating mixtures into their components. The process involves two phases. The first phase is stationary and provides a large surface area. The second phase is mobile and moves in a fixed direction relative to the stationary phase. Modern […]
What is the difference between an ECG, EEG, EMG and EOG?
An electrocardiogram (ECG or EKG), electroencephalogram (EEG), electromyogram (EMG) and electrooculogram (EOG) all measure biopotentials, the electrical output of human activity. However, the amplitude and bandwidth of the measurements vary for each of these. The table shows the values for each biopotential group according to the article “Biopotentials and Electrophysiology Measurements” in The Measurement, Instrumentation, […]
How will 5G technology impact sensors?
Fourth generation (4G) wireless cellular networks can theoretically download at speeds up to 100 Mbps, but a fifth generation (5G) network can achieve from 1-10 Gbps. While some fifth generation (5G) wireless cellular systems began operation in limited areas of the US and other parts of the world in 2018, 2019 should mark the real […]
What application problems do newly released sensors solve?
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 do you solve complex sensing application issues?
A common problem in applying an existing sensor (or many other products for that matter) to a new application is a shortcoming in one or more of the sensor’s capabilities. In some cases, the sensor’s specifications clearly show its limitations. So, what does an inventor or system designer do to overcome the limitations? For a […]
What market growth is expected for sensors? Part 3: Drone Sensors
Drones represent a focused application for many different types of sensors. In broad terms, the sensors in these applications can be classified as optical, acoustic, position, touch, environment and other sensors. More specifically, the sensor types include: inertial sensors (accelerometers, gyroscope, magnetometers, tilt), image sensors (infrared, thermal, multispectral, 3D), speed and distance sensors (radar, LiDAR, […]
What market growth is expected for sensors? Part 2: Gas Sensors
While there are several market research reports published each year for sensors, some focus on specific markets like industrial, automotive or consumer and others address a single sensor category. Gas sensors are an interesting example. In “Global Gas Sensor Market Study Report 2019,” QY Research says the global Gas Sensor market is valued at million […]
How is wearable technology impacting industrial applications?
Market research experts expect a growing adoption of wearable sensors in industrial facilities. Gloves with fabric-based sensors are one of the growing applications. While they were initially designed to improve the gaming experience and sports activities, lightweight gloves with highly sensitive and accurate sensors can increase productivity and safety in an industrial environment. For example, […]
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 […]
