In general, three-dimensional (3D) printing or additive manufacturing is the construction of a three-dimensional object from a digital 3D model. With 3D bioprinting, the 3D constructs are living cells, biomaterials, bioactive components, and more. In the 21st Century, the generation and transplantation of several tissues, including multilayered skin, bone, vascular grafts, tracheal splints, heart tissue, […]

How can sensors protect vulnerable areas? Pt 4
The U.S. Environmental Protection Agency (EPA) has ongoing efforts to address the unintended contamination and purposeful contamination of the nation’s water supplies. Sensing technologies are an integral part of the strategy. In 2023, the EPA proposed new limits to drinking water contamination from toxic “forever chemicals” or per fluoroalkyl and polyfluoroalkyl substances (PFAS). Used widely […]
How can sensors protect vulnerable areas? Pt 3
Today, advertisements for Camp Lejeune lawsuit settlements are frequently seen on cable and network TV. Another frequently cited water disaster occurred in Flint, Michigan. Detecting lead in drinking water On April 25, 2014, the City of Flint changed its water supply source from Lake Huron water (supplied by Detroit) to the Flint River. Subsequently, water […]
How can sensors protect vulnerable areas? Part 1
Clean air and water are essential for life. Protecting these valuable, essential elements, starts with sensors to detect threats from intentional or unintentional contamination. Today, available sensing technologies target different locations/areas to ensure the safe ongoing supply of fresh air and water. Using a variety of different sensing techniques, the key to broad and localized […]
How do sensors improve home appliances? Pt. 2
Part 1 of this blog discussed sensors in the laundry room in washing machines and dryers. In the kitchen, similar to the laundry room, basic functions can be designed in using established sensing techniques. In the typical home, the refrigerator is the second-largest consumer of electricity (13.7%), with the air conditioner being number one. So, […]
What’s the outlook for chemical sensors?
The current emphasis on providing products and materials with fewer environmental effects will have a direct impact on the chemical industry and chemical sensors. Obviously, this starts with, but is certainly not restricted to, reduced CO2 emissions. Chemical sensors have a wide range of applications, including healthcare, industrial, biotechnology, and household sensing requirements such as […]
How does air quality history impact data analysis?
Measuring air quality, like any other measurement process starts with the sensors. The sensors provide the concentration of different elements in the air such as CO2 and volatile organic compounds (VOCs) as well as other parametric data such as humidity, temperature, atmospheric pressure and light level that affect the ambient environment indoors – or outdoors. […]
How can low-cost sensors help address climate change?
According to the recent IDTechEx report “Printed and Flexible Sensors 2022-2032: Technologies, Players, Markets,” low cost printed/flexible sensor technologies could play a significant role in adapting to climate change [1]. Adapting could take various forms, from changing the areas in which specific crops are grown to building flood defense systems and even relocating cities in more […]
How can sensors help cleanup waterways?
Twenty years after its first-generation design was introduced (2002), iRobot’s Roomba has spawned many competitors for indoor cleanup and made several advancements to its initial capabilities. Interactive Autonomous Dynamic Systems (IADYS) has applied the autonomous robot concept to address cleaner and safer water in rivers, canals, lakes, ponds, shipyards and more. IADYS’ Jellyfishbot autonomously collects […]
How is biomarker sensing expanding?
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 […]
