JULY 20259ELECTRICAL BUSINESS REVIEWevolving into smart factories. Many of the assets within smart factories can be networked together. A dashboard that displays real time status of factory production allows factory workers to assess conditions of all machines right from their desk or even in the palm of their hand. Continuous developments in sensor technology will bring new types of measurements with more precision and accuracy providing additional data to optimize production. A key element of smart factories is the use of industrial cobots or collaborative robots. Cobots are intended to interact with and assist human workers as opposed to being standalone automated equipment with little to no human interaction and are considered the peak of cutting-edge robotic technology. Cobots in manufacturing environments can also handle complex or dangerous tasks that humans either cannot complete or cannot perform safely. Sensors are important to industrial cobots because they collect the data that enables successful and safe operation, which allows an increase in efficiency, productivity, and profitability. As new sensors are designed to enable mechanization of tasks traditionally performed by human factory workers, new types of cobots are being deployed to perform increasingly difficult tasks. One such task is positioning in assembly creation ­ locating and picking up needed components and placing them accordingly. Cobots are also extremely useful in inspection processes. Even when cobots are performing work, quality control requires human eyes for proper visual inspection. Robotically arranged cameras provide a look at multiple angles along the assembly line to a human worker, making inspection easier and more thorough. Sensors are Making Healthcare Equipment Smarter and More Efficient Just as the IoT is revolutionizing the industrial landscape, it is also doing the same for healthcare. Sensors are transforming patient monitoring and treatment, putting patients in better touch with their own health while making treatment more convenient and comfortable. Sensors within networked equipment are providing physicians with very precise data and accurate monitoring. Medical pumps are just one example. Medical pumps today, such as infusion pumps, hemodialysis, and blood flow monitoring applications, are becoming smarter thanks to sensors. Through the integration of highly advanced sensors, these devices are optimized for precision and reliability. Various sensors measure force, pressure, position, and temperature to maintain liquid levels and continuous flow, detect occlusion, and alert the user to potentially harmful air bubbles in lines. What's more, the advent of miniaturized and networked equipment has begun to allow procedures, like kidney dialysis, to take place patient's home rather than a doctor's office. From a patient care perspective, the benefits include making the treatment more convenient and comfortable. Ultimately this method should also more cost-effective for both the supplier and the patient. Another example of IoT at work in revolutionizing medicine is the treatment of sleep apnea. Previously, a sleep apnea diagnosis required a patient to stay overnight, wired to machines, in a sleep center. Sleep apnea patients were treated with a bulky, stationary CPAP machine. Advanced sensors have changed the diagnostic process for sleep apnea, allowing it to now be done at home, as well as treatment and accuracy of feedback informing the treating physician. In the CPAP machine itself, sensors measure pressure, vibration, temperature and humidity. In addition, photo optic sensors help diagnose sleep apnea by measuring blood oxygen levels, and a piezoelectric film measures vibrations in breathing, providing a status check on the patient.Finally, the Internet of Things has spurred an increase in consumer based, personalized health devices, leading to greater consumer awareness of the ability to monitor personal health. Sensors are a key component in wearable devices such as fitness trackers and heart rate monitors and can detect breathing rates, temperature, blood oxygen levels, glucose levels, hemoglobin and more. In the future, it is predicted that these devices will become even more precise and have the capacity to measure a wider variety of health factors, someday even detecting illnesses before symptoms appear. The bottom line is that IoT devices and equipment simply wouldn't function without sensors. Reliable, accurate sensors create a foundation for engineers to understand the various properties in applications and enable them to observe and report on the world around us. My colleagues and I at TE Connectivity continue to follow the trends, such as miniaturization and sensor fusion, in both the industrial and medical industries with an eye to the future and the goal of working toward an even more connected tomorrow.
