How Pressure Sensors Work Pressure Mapping Systems Sensor Technology At the heart of every Pressure Measurement System is an extremely thin (~0.1 mm), flexible tactile force sensor. Sensors come in both grid-based and single load cell configurations, and are available in a wide range of shapes, sizes and spatial resolutions (sensor spacing). These sensors are capable of measuring pressures ranging from 0-15 kPa to 0-175 MPa. Each application requires an optimal match between the dimensional characteristics of the object(s) to be tested and the spatial resolution and pressure range. Sensing locations within a matrix can be as small as .0009 square inches (.140 mm2); therefore, a one square centimeter area can contain an array of 170 of these locations. Sensors have been created covering 256 square inches (1600 square centimeters) with over 100,000 sensing locations. The Virtual System Architecture (VSA) allows the user to integrate several sensors into a uniform whole. Application in Chemical Mechanical Polishing.
Our Makerspace Journey The Stewart Middle Magnet School Library Makerspace Journey I first started my makerspace journey at Stewart Middle Magnet School in January 2014 with a few bins of K’nex spread out on some library tables. It then grew and expanded into a thriving program and a vital part of the library and school. Take a look back at our journey and see what we learned along the way. The Makerspace changed, grew and evolved since it was first conceived and started in January 2014. Follow along with the first two years of the story here. (Note: I left Stewart in May 2017, but the makerspace there continues to grow. Quick Background on Stewart Our school was originally Blake High School, a segregated high school that opened in the 1950s. Our school has a focus on engineering, robotics, aerospace and video game design.
E. Preston (Electrical) Ltd » Blog Archive » Honeywell Extends Its TruStability® Pressure Sensor Product Line with a Single Side Liquid Media Option Allows One Sensor Port to Be Used with Condensing Humidity or Directly with Non-corrosive Liquid Media Honeywell introduced a single side liquid media option to its extensive line of TruStability® Pressure Sensors originally introduced in July 2009. The new single side liquid media option allows customers to use one port of the sensor with condensing humidity or non-corrosive liquid media, such as de-ionized water, eliminating the complexity and expense of having to protect the sensor from this type of media. Honeywell has developed this option because of the many applications where condensing humidity conditions exist or where liquid media is the desired media to be measured. Until now, Honeywell’s TruStability® Pressure Sensors have been intended for use with non-corrosive, non-ionic working fluids such as air and dry gases. * Temperature compensated and calibrated, providing an extremely tight accuracy specification; Both series offer the option of analog or digital outputs.
Makerspaces as classrooms: schools and hardware shops partner Klint Kanopka still remembers the time when technology’s purpose in school could be boiled down to defeating your classmates on the Oregon Trail. “And even shop class used to carry a negative stigma, and it was never really taken seriously,” Kanopka said. Today, the flourishing of makerspaces in Philadelphia is meeting a local tech community commitment to growing STEM learning in schools to bring about new goals . Earlier this year, the makerspace at the Academy at Palumbo was just a storage room. “It’s still slow, it’s still growing, and we’re still getting more stuff in here,” Kanopka said. Academy at Palumbo physics teacher Klint Kanopka. Right now, he uses the space as an extension of his physics classroom, where he can teach CAD seminars on their Makerbot 3D printer, and how to work with Arduinos, the easy-to-use, circuit boards designed to help create interactive objects. “If they have an idea for something they want to create, they can come in and we’ll discuss it,” Kanopka said.
NanoEngineers Print and Test Chemical Sensors on Elastic Waistbands of Underwear NanoEngineers Print and Test Chemical Sensors on Elastic Waistbands of Underwear June 17, 2010 By Daniel Kane Chemical sensors printed directly on elastic underwear waistbands retained their sensing abilities even after engineers stretched, folded and pulled at the chemical-sensing printable electrodes – sensors that could one day be incorporated into intelligent “hospital-on-a-chip” systems. The primary goal of the new peer-reviewed study, published in the journal Analyst, was to aggressively test the performance of electrodes printed directly on textiles, something the researchers say has not been done before. The “smart” in “smart underwear” refers to the fact that the printed sensors will be incorporated into logic-based biocomputing systems that will monitor biomarkers found in human sweat and tears, make autonomous diagnoses, and administer drugs. A 2008 ONR grant announcement from UC San Diego introduced this project. “We just want the ones and zeros.
How to Turn Any Classroom Into a Makerspace There is a certain magic found in rolling up your sleeves and tackling a project head on, an undeniable sense of empowerment that results from solving problems and manifesting big ideas. In essence, that’s the soul of the maker movement — creative individuals from all walks of life united by an insatiable desire to improve the world around them. Although synonymous with 3D Printing, it extends far beyond a single technology or buzzword. Truth be told, the maker movement represents the instinctual drive of our species to ascend ever upwards: to innovate, design, and construct a better tomorrow. Why the Maker Movement is Relevant to Education Image via Flickr by Exploratorium When I was a child, playing the classic game Oregon Trails was the extent of my technological wizardry. Below, you’ll find projects capable of turning any classroom into a true makerspace. Hydroponic Gardening The National Gardening Association envisions a garden in every American school.

Glove Pressure Mapping System The Glove Pressure Mapping System (GPMS) is a multi-sensor hand force data acquisition system that consists of an Ultrathin Glove Mat and a Computer Interface. The GPMS incorporates the ISS sensors in 20 and 24 sensor configurations. The sensor locations can easily be modified by the customer and are mounted using double-sided tapes. The individual sensors are covered with a Teflon coated laminate which makes them more durable. The GPMS has various ergonomics applications including hand-tool analysis, design and research, as well as clinical applications. Twenty and twenty-four sensors are used in the standard configurations that results in a sampling rate of over 100 Hz. Sample Results Glove Configurations Gloves are designed to fit both left and right hands (ambidextrous) and can be ordered in various sizes as shown below: How to Measure for Proper SizingTake a measuring tape and wrap around the hand over the knuckles.
