This Block Of Rubber Can Count To Ten

Complex behaviors can arise from simple mechanics, and that’s demonstrated by a block of rubber that acts as a counter. The block contains beams, and by controlling how the block is compresse…

3D-Printing Complex Sensors And Controls With Metamaterials

If you’ve got a mechatronic project in mind, a 3D printer can be a big help. Gears, levers, adapters, enclosures — if you can dream it up, a 3D printer can probably churn out a useful p…

Optical Microscope Resolves Down To 40 Nanometers

Optical microscopes depend on light, of course, but they are also limited by that same light. Typically, anything under 200 nanometers just blurs together because of the wavelength of the light bei…
