Current “No-Touch” Technologies Available
EPS Sensor: Scientists were able to monitor a person’s heartbeat and breathing using a sensor mounted 5mm away from the body. What makes this extraordinary is that this was accomplished with the person sitting in an ordinary room (containing other noisy electrical equipment)!
- A second generation of the EPS Sensor could do the same, but located 40 cm away from the body. Second article here.
- The third generation of the EPS Sensor could measure EEG signals with the sensor mounted 4mm away from the body! This is awesome, as most devices need to touch the skin to work when reading EEG.
Optical Magnetometer: (an optical device used to detect and measure extremely subtle magnetic fields) was used to sense the magnetic fields generated by a frog’s nerves from a few millimeters away.
Wireless Signals: A professor used a device that uses AI and wireless signals to interpret signal reflections off the body to detect an individuals breathing, heart rate, sleep, gait, and more. It has been installed in the homes of those suffering conditions like Parkinson’s, Alzheimer’s, depression, and pulmonary diseases.
Laser: Physicists have worked out how to use a laser to measure the magnetic fields generated by single nerves from outside the body and at room temperature.
Light: Here is an article on how scientists have been able to read and write brain activity using light!
“No Touch” Research Currently Underway
US DARPA is pushing magnetic field sensing to a new era with the “Atomic Magnetometer for Biological Imaging In Earth’s Native Terrain (AMBIIENT) program”. The AMBIIENT program promises the ability to read the magnetic field generated by the body without needing the subject to be shielded from the Earth’s magnetic field.
Available Technologies Not Yet Associated With Biological Signals
As it is often noted that it is not possible to read ultra-weak signals in a noisy environment, I offer the following articles for your consideration. Most people are unaware as to just how sensitive some equipment has become, and of our capabilities:
Atomic Radio: A newer technology, dubbed Atomic Radio, can detect RF signals between 2.5 to 15 centimeters (2 to 12 GHz) using Rydberg atoms. Rydberg atoms are cesium atoms with their outer electrons having been so excited that they orbit the nucleus at great distance. When the electrons’ potential energy levels are extremely closely spaced they exhibit special properties – a small electric field in their vicinity will move them to a different level (this effectively makes them sensors). A gas made of Rydberg atoms can become transparent when a tuned laser is used on it, as it essentially saturates the gas’s ability to absorb light, allowing another laser to pass through it. As the electrical field interacts, the electrons change orbit, affecting the gas saturation, which can be detected by the second laser. This laser signal is captured and we are able to determine how the radio signals are modulated (frequency or amplitude modulation).
