Anomalous Bluetooth address readings when people approach me and off as they walk away.

REMEMBER. What is now being studied above ground and advertised as state of the art research soon to be commercially available has already been done under covert black budget a decade ago or more.

Injectable computers can broadcast from inside the body

<50%

This platform has enabled a variety of sensors that can fit inside the human body, made possible by several breakthroughs in ultra-low power computing.

Profs. David Blaauw and David Wenzloff are designing millimeter-scale ultra-low-power sensing systems that can be injected into the body through a syringe. Unlike other radios of this size, these new devices are able to broadcast through the human body to an external receiver.

Teeny-Tiny Bluetooth Transmitter Runs on Less Than 1 Milliwatt Bluetooth Low Energy data packets can now be sent by millimeter-size IoT motes

<50%

Engineers at the University of Michigan have now built the first millimeter-scale stand-alone device that speaks BLE. Consuming just 0.6 milliwatts during transmission, it would broadcast for 11 years using a typical 5.8-millimeter coin battery. Such a millimeter-scale BLE radio would allow these ant-size sensors to communicate with ordinary equipment, even a smartphone.

Wireless, power-free and implantable nanosystem for resistance-based biodetection

Abstract
In-vivo devices and systems are extensively used in medical field to real-time detect and adjust the physiological status of human being, but supplying energy in-vivo for these devices and systems is still a great challenge. In this work, we first developed a new kind of wireless nanogenerator (WLNG) based on biocompatible BZT-BCT nanowires (NWs).
