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 blind or visually impaired users can navigate around those areas. Additional sensors in the research prototype include GPS, accelerometers, magnetometers and gyroscopes to monitor the user’s […]
What sensors are in a smart cane? Pt 1
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 […]
How has sensing in industrial automation changed? (Part 3)
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 […]
How has sensing in industrial automation changed? (Part 2)
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, […]
How are multi-axis sensors improving product development?
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 […]
How has sensing changed in industrial automation? (Part 1)
The Industrial Revolution or what we might call Industry 1.0 started over 250 years ago. In 1771 Richard Arkwright, today known as Father of the Factory System, used water to power the first fully automated spinning mill. One hundred years later, the automotive assembly line initiated the Second Industrial Revolution or Industry 2.0 with significantly […]
What sensing events will be held in 2022?
January is a great time to line up major sensing activities for the rest of the year. The following provide an idea of what will occur in 2022 for sensor experts to attend or present the results of their recent efforts. Fast approaching, the 7th Annual Sensors Global Summit 2022 will be held March 2-3 […]
How can you sense ripening fruit?
A diet high in fruit (and vegetables) can reduce the risk of developing heart disease, cancer, inflammation and diabetes. But the fruit needs to be fresh for a sustainable, healthy diet. Several techniques are being used to detect ripening fruit. One company, smartGAS in Germany, has two different sensors to detect the ethylene (C2H4) that […]
How can you see through walls?
It depends on what you want to “see” and how much you want to pay. To locate a stud, the old school technique of tapping a tool on the wall for acoustic differences used hearing rather than sight and it was free. Initially, battery-operated stud finders used magnets to find screws and nails and provided […]
How can smart sensors help solve the supply chain problem?
According to a recent article/analysis from Deloitte, (Smart sensors and supply chain innovation), “Companies should consider investing in smart sensors to increase value capture through their supply chains after carefully prioritizing their business objectives and defining their use cases.” Several recent developments lead them to this recommendation. The capabilities of today’s smart sensors are a […]
