You would need to connect wires to that little 40 um^2 mote to do anything, though, which in practice makes the rigid places needing strain relief a lot larger.

- marshray 2y agoIt also makes the amount of strain proportionately smaller. We're talking about a 3mm bend radius here, so there's a few orders of magnitude to work with.
- mlyle 2y agoNot as many as you think, because you need to have targets bigger than the ~20um wirebond wire to solder to... and the little wire and bond pad are not very tolerant of strain at all. Bonding wires to the thing in the first place easily increases its size by a couple of orders of magnitude.
