Advanced sensors could use rubberized laser beams
Lasers usually conjure up the image of bulky devices with mirrors inside that shine a coherent beam out one end. However, scientists from Kent University have created a model that's just a flat piece of stretchy LCE (liquid crystal elastomer) film. That material is like a rubberized version of the liquid crystals used in displays and is often used to make artificial muscles. When hit with a simple laser light source, the film produces a new laser beam that changes frequency when force is applied. That alone is cool (to laser people), but the new material may also result in a new class of sensors that can measure forces with extreme accuracy and relay the results over fiber optic cables.
Tunable app shows musicians what pitch-perfect means as they play (video)
Musicians who've had some degree of practice will know the lack of sophistication involved in getting an instrument in tune and on time: a light-up tuning box and a swinging metronome may be their only real resources. Affinity Blue knows that mobile apps allow better, and recently unveiled Tunable as a one-stop shop for more exacting performers. The Android and iOS release provides a live graph that shows where the sweet spot is for pitch, and how closely the music has followed along for the past few seconds -- a boon for brass players, vocalists and others who need to sustain a note for more than a moment. There's also a simple tone generator and a customizable metronome that's easily seen from a distance. While it's $1 to try Tunable, that might be a pittance for anyone who'd rather spend time mastering a riff than rehashing the basics.
