Vibrating beams are like dartboards

The upper plot in this video shows the “basins of attraction” for a bistable compressed beam as you bend its support angle from flat (0 degrees) to about 18 degrees. This beam is about 4% too large to fit in its assigned area, so the center pops up or down. From our earlier work we …

Calculate your spin speed for SU-8 photoresist

Dragging an ancient, stained cleanroom notebook around (NO DRINKING COFFEE IN THE LAB!) or constantly digging up the MicroChem SU-8 datasheets to calculate your SU-8 spin speed? Check out our SU-8 Spin Calc. SU-8 is a thick photoresist often used for making molds for microfluidic devices. Since the photoresist is part of the final structure, …
