It’s one of those good problems.
You’ve been doing some exploratory MEMS work. Your main focus is biomedical – implants for dealing with prostate cancer. Silicon is too brittle, so you do some exploration with a foundry to experiment with different structures and materials. A nickel alloy looks interesting – more forgiving than silicon (at the expense of a lower Young’s modulus). And there’s some extra space on the die.
One a whim, you and a co-researcher half-jokingly discuss putting a windmill on there. During the discussion, … Read More → "Micro-Windmill Surprise"
