SLAM (simultaneous localization and mapping) is used in autonomous vehicles of all types to build a map and simultaneously locate the vehicle in that map. SLAM algorithms allow the vehicle to analyze and map out unknown environments. With this map information, the vehicle can implement path planning and obstacle avoidance. Visual SLAM uses cameras and/or […]

Network security involves software and computer-based hardware/firmware to provide access to the authorized and restrict access to the unauthorized. In contrast, physical or brick and mortar security starts with sensors and, if the security system is connected to the internet, it also requires the same network security measures. Protecting a residence, commercial building or an […]

In addition to radar, LiDAR and camera sensing used in 3D obstacle detection and collision avoidance in advanced driver assistance systems (ADAS) in vehicles, ultrasonic sensing has been used as well. Traditionally, the ultrasonic sensors used transducer-based technology to provide a microphone to transmit and receive the ultrasonic signal in passenger vehicle parking applications. Using Infineon’s […]

When Willis Carrier designed a system of fans, ducts and perforated pipes, which became the first modern electric air conditioner (AC) in 1902 (120 years ago), sensing was not part of the bill of materials. Devon Brock, Manager of Product Knowledge and Training, Sensors Group at TE Connectivity provides some insight into subsequent AC systems. […]

Using the time-of-flight (ToF) principle, a ToF sensor measures the distance between the sensor and an object. The sensor emits a signal that is reflected off an object and then detects the time for a round trip to occur. Typically, either light or sound waves can provide the transmitted signal.  In either case, the distance […]

Buoys were historically employed as simple mechanical structures to identify a safe navigation route or mark hazards such as reefs and below the surface rocks. The addition of battery and lights brought an electrical aspect to them and increased their visibility at night. These days a buoy can be part of the Internet of Things […]

Pathogens, infectious agents that cause disease, can include microscopic viruses, bacteria, fungi and protozoa. Both biomarkers and biosensors can detect and identify pathogenic agents. After using biomarkers to measure and detect pathogenic factors and assess biological conditions., drugs can be delivered to the target tissue so that other tissues are not damaged. Biomarkers are widely […]

The answer depends on how harsh of an environment and how much protection is required. For a microelectromechanical systems (MEMS) microphone, one of the most-harsh environments is the human body, since sweat and dirt can cause failures in traditional MEMS microphone architectures. Regarding the protection, the International Electrochemical Commission’s (IEC’s) IEC 60529 rating system defines different […]

Inspired by self-driving vehicles and robotics, the Augmented Cane developed by Stanford University researchers uses a LiDAR sensor to measure distance to nearby obstacles and then provide directions so users can navigate around those areas. Additional sensors in the research prototype include GPS, accelerometers, magnetometers and gyroscopes to monitor the user’s position, speed, direction and […]

Blind or visually impaired individuals have to rely on other senses and typically have heightened capability – especially for hearing and touch. Using a white cane provides feedback in both of these areas. World Health Organization (WHO) data says that there are more than 253 million visually impaired people worldwide. Many of these individuals rely […]

In Industry 4.0, another sensor-specific aspect that customers are asking for is packaging that can survive in different harsh factory environments. “When you’re putting them on an oil platform or in a factory or on a motor or in a steel mill or in a paper mill, in those really harsh environments, they need to […]

Sensing has changed a lot since the early days of industrial automation. “Back 250 years ago, your sensors were actually people. They were your manufacturing engineers that would walk around and listen to the machines and hear what’s going on,” says John Tuley, from IoT Business Development -Sensor Solutions at TE Connectivity. In Industry 4.0, […]

With a multi–axis sensor design, a single load cell sensor can measure 3 axes of force and 3 torque moments simultaneously. These sensors consist of multiple bridges that precisely measure the applied force from one direction with minimal crosstalk from the other axes. Using a multi-axis sensor, forces can be measured simultaneously in three mutually […]

The Industrial Revolution or what we might call Industry 1.0 started over 250 years ago.
