Haptics is the science of simulating pressure, texture, vibration and other sensations related to touch. Most of today's haptic devices rely on motors that either prod or vibrate the skin, but a new technology is emerging that is an even more flexible and effective means of stimulating the sense of touch: skin stretch. By laterally stretching the surface of the skin (without pushing or poking into it) it is possible to mimic the feeling of complex shapes and sensations. This is because the sense of touch seems to depend far more on the way in which the skin is deformed and stretched than it does on the degree of pressure applied. So it should be possible to recreate sensations purely by stretching skin, says Vincent Hayward, a researcher who first developed such a device at the Centre for Intelligent Machines at McGill University.
On March 8, Environmental Health & Safety (EHS) will host a web-based safety seminar being organized by the American Industrial Hygiene Association on nanoparticles. There will be four presentations: "Practical Measurement Techniques for Airborne Nanoparticles in the Workplace"; "Relating Nanoparticle Exposures to Respiratory Dose or Body Burden"; "Characterizing and Controlling Exposures to Nanoparticles in the Workplace"; "Regulatory and Risk Overview for Managing Nanomaterials Along the Product Life Cycle."
