A 39-year-old woman presented to the dermatology department in January 2022 with a 3-week history of a progressively enlarging and intensely pruritic erythematous annular nodule on her left hand. The lesion started as a small blister, which was initially presumed to be a flare up of her pompholyx dermatitis. On her physician's advice, she applied clobetasol propionate ointment twice daily for 5 days; however the blister continued to increase in size until it burst, revealing raw inflamed skin.

Various electric protocols have been explored for different objectives, including the utilization of fractionated pulse doses to enhance cell electrosensitization to the uptake of different markers or an increase in apoptosis. This study focused on the use of fluorescence imaging to examine molecular calcium fluxes induced by different fractionated protocols of short electric pulses in neuroblastoma (SH-SY5Y) and mesenchymal stem cells (HaMSCs) that were electroporated using nanosecond pulsed electric fields.

Vibrational energy harvesters are a potential solution for powering these sensors, as vibrations commonly exist where monitoring occurs. Developments in low-power circuitry have also led to the feasibility of these types of harvesters.
