According to the Center for Disease Control (CDC) estimates, 22 million workers are exposed to potentially damaging noise at work each year. In addition to an industrial environment with heavy assembly/processing machinery or a construction site, the workplace can include a sports venue, a tarmac, or a wide-open space when the job includes machinery that […]
How is sensing used in audio acquisition and broadcasting? Part 1
According to the proverb, “seeing is believing,” but hearing something before you can see it can be very important, too. The earliest humans heard and recognized the sounds of predators long before they could see them. If they could see them — it was probably too late to take evasive action. While sound has always […]
How is sensing involved in deep sea exploration?
As the recent loss of OceanGate’s Titan tourist vessel has revealed, exploring in the ocean’s depths is very risky business. To see the Titanic up close and personal, the Titan would have to travel to a depth of 3,800 m (12,467 ft), where the pressure is 382.45 bar (5,547.14 psi or 38,246.06 kPa). It turns […]
How does sensing help in paranormal research?
Paranormal does not usually imply a scientifically sound phenomenon. However, when science is used to verify the observation, the situation changes. This is where a variety of sensors come into play. After all, it is called extra sensory perception (ESP). In the United States, a push in the scientific community to empirically study paranormal experiences […]
Has interest in particulate matter sensing increased?
Traditionally, summer wildfires are associated with California and the west coast. With the recent Canadian wildfires spreading smoke and dense particulates to extensive areas in the eastern and southern U.S., monitoring outdoor particulates has become an important topic for areas of the U.S. that are not normally that interested. On June 8, the U.S. National […]
How is skin sensing for robots advancing?
Robots need numerous sensors and various sensing technologies to perform a variety of functions. However, for human-robot Interaction, the most important sensing could be performed in the skin — especially in those robots designed to be as lifelike as possible and physically interface with (touch) humans. To enhance the collaboration between humans and machines, the […]
Has integrated sensor and circuitry reached a new milestone?
Since the earliest days of microelectromechanical systems (MEMS) sensor products, the goal of easily combining the sensing structures made using MEMS processing with the required signal conditioning has driven many sensor R&D labs. If successful, the solution would make the resulting devices more useful in a broader range of applications. In the 1980s, the circuitry […]
How are sensors used in 3D bioprinting?
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 […]
What is sensor activated?
Some of the earliest uses for sensors that emerged over a hundred years ago involved direct actuation for control. Think of the mercury thermostat. A thermally responsive coil moves with changes in temperature and tilts a mercury chamber until it closes a set of contacts to turn on a heater in the home or office […]
What are quantum sensors?
Quantum sensors measure minute changes in electric and magnetic fields as well as motion and the measurements are made at the atomic level. At this scale, information from individual atoms instead of from huge collections of atoms allows quantum sensors to make exponentially more accurate, more thorough, more efficient and more productive measurements. Using the […]
