Enthalpy Posted September 21, 2019 Posted September 21, 2019 It may be worth repeating that the present scientific consensus is against electrosensitivity at humans. I haven't heard of one experiment that succeeded detecting an electrosensitive person. Science evolves, though, as it did about ball lightning. Many bird species are sensitive to the geomagnetic field. Possibly humans, or some persons, have a sensitivity to the electric of magnetic field. After all, microwaves serve to speed up some chemical reactions, despite the process isn't understood. The self-discharge of a battery creates no current loop the size of this battery, and the equivalent intensity is tiny, so it would produce no magnetic field comparable to the mains or a battery in duty. Could some people sense a DC field created by the battery? Birds do it for the magnetic field. I believe it's impossible for the electric field, because the air is an insulator and the skin a sufficient conductor to short the electric field. But exotic processes could sense a DC electric field, maybe if skin hairs vibrate, so they change their position in the field. They wouldn't sense exactly a DC electric field, but a slowly varying one yes, say if approaching the source. Normal people live in electric and magnetic fields, both DC and AC, much stronger than that and they notice nothing.

studiot Posted September 21, 2019 Posted September 21, 2019 Biological responses to imposed electric fields have been known and studied since at least the 1960s. Acceleration of wound healing is one positive one. https://www.acs.org/content/acs/en/pressroom/presspacs/2018/acs-presspac-december-19-2018/e-bandage-generates-electricity-speeds-wound-healing-in-rats.html Google has many articles. 1

The proposed case is a battery in the pocket, supposedly isolated from the person by the fabric. Then no permanent effect is expected.

Enthalpy Posted September 22, 2019 Author Posted September 22, 2019 No, they propose a contact and measure a DC current.

We are talking about an electric field not an electric current here. For instance Quote Some experiments indicate that when the electric field is removed the wound healing rate is 25% slower. In addition, nearly every clinical trial using electric fields to stimulate healing in mammalian wounds reports a significant increase in the rate of healing from 13 to 50%.
