Monday, March 13, 2023 Our solution for Paper A 2023 - Electric plaster for skin problems

Here's our attempt at this year's paper A.  

The topic was electric plasters for treating skin. A voltage was created by placing a triboelectric material between two copper sheets. The voltage is then transferred to the skin. This can have a medical application, treatment of wounds, or a non-medial application, treatment of wrinkles. 

EQE aficionados might consider this a sequel to paper C of 2012. First impression is a well made paper without major problems. The focus was mostly on E/M issues. 

You can find our attempt and discussion at the 'read more' below. 

[Update 14/3/2023:] We also added the full text and figures of the paper at the end of the blog post for easy reference.

We look forward to your comments!

Please do not post your comments anonymously - it is allowed, but it makes responding more difficult and rather clumsy ("Dear Mr/Mrs/Ms Anonymous of 02-03-2021 22:23"), whereas using your real name or a nickname is more personal, more interesting and makes a more attractive conversation. You do not need to log in or make an account - it is OK to just put your (nick) name at the end of your post.
