"This medical grade Silver plated 76% Nylon, 24% elastic fiber fabric offers the unique ability to stretch in both directions. Can be used as an antibacterial wound dressing (note: our material is not sterile) but it also makes a great material for electrode contacts, stretchy hats, socks, gloves, or other garments. Highly conductive, and conductivity increases as it stretches in one direction, and decreases as it stretches in the other direction. Silver coating is 99.9% pure. Silver/gray color."
Shielding performance: 30-50 dB, tested from 1-10 GHz Width: 135 cm wide (52 inches) but varies from lot to lot Weight: 4.3 oz/yd² Thickness: 0.40 mm Stretch: ~100% in length direction; ~65% in width direction Surface resistivity is < 1 Ohm/sq. (unstretched) Temperature range: -30 to 90°C
"Create capacitive sensors that can detect touch or proximity. The capacitiveSensor library turns two or more Arduino pins into a capacitive sensor, which can sense the electrical capacitance of the human body. All the sensor setup requires is a medium to high value resistor and a piece of wire and a small (to large) piece of aluminum foil on the end. At its most sensitive, the sensor will start to sense a hand or body inches away from the sensor."
"These sensors measure pressure and can also be designed and placed to measure bend. They work on the simple principal that Velostat reacts to pressure with a decrease in electrical resistance. When sandwiched between two conductive layers, this change in resistance can be easily measured and used as an indication of how much pressure is being applied."
"Stitching conductive thread into neoprene to create a pressure sensitive pad. This sensor is very similar to the Fabric Bend Sensor or vis-versa. And also close to the Fabric Pressure Sensor, but the difference is that the conductive surface is minimized by stitching only a few stitches on either side with conductive thread. This creates a good fingertip pressure range."
"Interrupts are useful for making things happen automatically in microcontroller programs and can help solve timing problems. Good tasks for using an interrupt may include reading a rotary encoder, or monitoring user input."
