Abstract: The invention proposes a novel process for both monitoring and reducing disturbing alternating electromagnetic fields in the human organism and helps prevent long-term damage. A measuring aid for the accurate measurement of low charges on the human body (from 0.1 to 100 V a.c.), especially on the skin, is also proposed. The measuring aid can be earthed, takes the form of an a.c. voltage meter and has a permanent or attachable skin contact point for measuring and displaying the true electric a.c. voltage directly on the human body. The invention makes it possible for the first time precisely to detect the effect and ratio of the electromagnetic a.c. fields and the electromagnetic waves in order to find a strategy for reducing the disturbing effect of electrosmog.

Abstract: An esophageal/stomach placement electrode comprises a flexible tubular member designed to be inserted into the esophagus and/or stomach. An electrode (14) is disposed at the distal end (12) of the tube (10). The tube is hinged so that the end of the tube is capable of moving laterally in the esophagus or the stomach. An actuating mechanism is disposed on the tube in the region of the hinge and causes the distal end of the tube to move laterally and engage the esophagus or stomach. The actuating mechanism is controlled from a location external from the body. The inner portion (27a) of the hinge is more bendable than the outer portion (27b). Additionally, the control cables that move the actuating mechanism are all within the tubular member.
