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.
