[labnetwork] Device on PDMS

[Mohamed Ghoneim]

**This might work for having electrodes on PDMS without running into
thermal expansion/shrinking issues.....but it depends on what you are
trying to do ultimately.

**You can also try transfer printing the electrodes or using the
traditional process with PR (additive or lift-off) but with slower heating
up and cooling down rates (sometimes, moving to 70% of required temperature
then 100% does the trick and same when cooling down to room temperature).

Best of luck and wish you all a great day!
