Intent: To create a technological equivalent to the “Blood Trail” ability
Development Thread: http://starwarsrp.net/topic/42510-blood-trail/
Manufacturer: InnoteQ
Model: Q73 Tracking Chip
Affiliation: Private Market
Modularity: No
Production: Limited (very expensive and use must be justified)
Material: Spintronic chip components (potentially iron and magnesium oxide layers)
Description: The Q73 tracking chip was developed into a response to track targets across large distances without alerting them to the signal. As no hyperwave technologies exist on this scale, and any signal of this magnitude would be easily detected InnoteQ thought up a novel approach to meet this challenge.
Each chip consists of a nano-receiver that detects any nearby wireless networks and uses this to find an approximate position.
This position is then fed into a three-dimensional spintronic lattice of a miniscule memory chip, according to a pre-defined binary location reference system.
This chip had been quantum entangled with another chip at one of Spynet’s headquarters. This change to position is read off and the location of the other transmitter recorded.
The chip is incredibly small, see diagram, and easy to secrete on a person. It can be placed under a nail or in the surface of a metallic object belonging to a target to reduce the chance of detection. It is exceptionally difficult to find, even with a significant scan.
However, it is not sizable enough for EM shielding. Powerful scanners, proximity to ship’s engines or a reactor could all break the device. Given the cost of each unit, which is approximately a million credits, this is a significant drawback. The device also requires the target to be in a public area with public wireless access points. This covers a significant fraction of populated regions of the galaxy, however it can’t track someone on a military or personal vessel and it is unable to locate itself on an undeveloped world.
OOC: This is my attempt to come up with a technological equivalent to a blood trail and took some significant thought on the problem. DUST had been used on this site to track people across systems, however I considered this completely implausible given the size of the transmitters, the speed of light and the power required to transmit over such distances. Instead I turned to quantum entanglement. This may/or may not have a good grounding in science, but I think it has enough of a basis in science fiction / fantasy work to get away with the concept. More detail in the mock scientific article in the dev thread.
