MEMORANDUM FOR: Deputy Director of Research and Development
SUBJECT : Remote Physiological Monitoring
1. Recent Surveyor issues have noted reports by the Russians
Gulyayev and Sergeyev claiming, respectively, that remote (wireless)
electroaurograms of the human chest and electroencepholograms have
been obtained. The device developed for the electroaurogram detects
very weak electrical fields at a distance up to 25 am. while the com-
ment on Sergeyev's work notes that "this report appears
to be the first claim of brain-wave recording some 15-20 feet distant
from the subject and without contact."
2. Regarding Gulyayev's work on electroaurograms, it is my
personal opinion that the report is credible. Similar work, currently
funded by this division, corroborates it. By means of a newly
developed monitoring system consisting of whip antennae and high
impedance matching circuits, electrical-field changes originating
from the human body were detected. The energy of these signals is
predominantly concentrated at frequencies below 30 Hz., is time vary-
ing in nature and accurately reflects both cardiac and respiratory
activity, and is also quite sensitive to the distortional influences
of body movement of a gross nature (motion artifact). This indirect
signal is somewhat time-dependent, diminishing slightly during the
first eight to ten minutes and thereafter remaining constant.
Against this background of slow undulations of respiratory origin,
there can be detected a more rapidly occurring event which is simul-
taneous with the pulse. Of greatest significance, however, appears
to be the qualitative appearance of the signal. With antennae
located at both the head and the feet, there is observable a wave
form which is remarkably similar to that of the direct ballistocar-
diogram and which occurs in phase with the ballistocardiogram without
a discernible lag. The first components of this pattern occur approxi-
mately 70-80 milliseconds after the R wave of the electrocardiogram.
This suggests that these signals are reflecting the symmetrical
expansions of the extracorporeal electrical field. The transient
increase in extremely low-frequency amplitude that one obtains with
bias change points to the redistribution of body surface charge which

accompanies a change in body surface area as the cause of the extremely
low-frequency signal. As the skin vibrates at points where the arteries
are nearest the surface and the chest wall moves with the action of
the heart, a redistribution current causes a potential drop across
the skin surface. This surface potential, as we have already noted,
is in motion with the skin and with respect to the antenna. It is
seen by the antenna as a changing E field. If an individual's skin
becomes more moist due to increased perspiration or relative humidity
or both, the potential decreases and so does the ELF signal.
3. It is very unlikely that streaming or bio-potential is a
significant cause of ELF. If the signal is caused by a streaming
potential, then a current dipole must exist along an artery or anywhere
that the streaming potential is developed. It is known that when a
dipole receiving antenna is perpendicular to a current dipole, the
signal received is a minimum signal. Where it is parallel, the signal
is a maximum one. We rotated a whip receiving antenna with respect
to the brachial and femoral arteries while the limbs were within limb
shrouds and with respect to the whole body outside a shroud. There
was no signal amplitude change with rotation. We therefore conclude
that it is very unlikely that streaming potential is a significant
cause of ELF.
4. Our contractor, has
developed prototype hardware which passively detects the above
described body-generated electric fields in a typical ambient noise
environment. Cardiovascular and respiratory signals can be obtained
readily at a distance of eight feet, and gross movement can be
detected at more than fifty feet. Our present follow-on effort with
Iwill develop equipment featuring convenient portability, improved
on-line processing techniques and readouts, increased range, and an
equivalent of directional selectivity through differential detector
methods. You will note that our work distance of eight feet is con-
siderably greater than Gulyayev's reported range of "up to 25 cm."
You will also note that our findings agree with his regarding the
field's maximum strength, i.e. its maximum value coincides with the
contraction of the heart muscle.
5. A personal evaluation of Professor Sergeyev's wireless
electroencepholograms cannot be made at this time. Studies are in
progress however, utilizing available low-frequency magnetometers,
to evaluate his claims. The traditional assumption that it is
impossible to measure emanations of brain waves remotely, would
seem still scientifically prudent. Research meetings with Drs.
