This device is not related to any canon source in the Star Wars universe, and is thus classified as fanon.

A Force suppression collar is a device worn round the neck which inhibits the use of the Force by the wearer. It is typically placed around the necks of Force-sensitives when captured as slaves or prisoners.


The aim of all Force collars, regardless of method is to disrupt either the wearer's ability to feel or interact with the Force. There is no know way to employ a simple collar to completely block the flow of the Force through the wearer, only block the wearer's ability to feel or control the Force.


Ultrasonic pulses are emitted repeatedly in close contact to the wearer's body, which mimics the 'sensation' of the Force. Consequently the wearer would attempt to control the artificial Force to no effect. This type of collar is generally considered the most comfortable for Force users, since it does not produce the painful sensations which are present in electric colors, nor does it create the 'cut-off' feeling which reactive and chemical collars can induce. The typical price tag for an ultrasonic collar is 1,000-4,000 credits. Ultrasonic levels are typically adjustable from 500-12,000 cycles; with some deluxe models offering up to 70,000 cycles (well above what is considered necessary).


Electric Force collars are designed to detect the physiochemical reactions present in Force users when they are actively communing with the Force, and disrupt those reactions using focused micro or macro bursts of electricity to the wearer's nervous system. Electric Force collars typically produce extremely painful sensations when the wearer attempts to use the Force. Electric collars usually have a built in ability to administer punitive shocks as well. Battery charge-life ranges between 16-36 hours at full effectiveness, depending on resistance from the wearer, with batteries themself lasting anywhere from 3-6 years depending on operating conditions. Electrocution risks have been seen to increase with prolonged operation in humid environments. These collars are not recommended for operation underwater. These collars are by far the most common in use, and price ranged from 800-2,000 credits, with voltage between 50-200,000 volts. Amperages are typically regulated to be non-lethal; however unlocked models are available on the black market which can cause intentional electrocution.


Chemical Force collars are loaded with variable-dose injectors containing drugs which cause the centers of the brain which control Force-interaction to atrophy. Chemical collars often contain a fast acting sedative to depress the wearer's central nervous system, and a stronger drug which takes several minutes to take effect which actually depress the ability to control the Force itself. Chemical collars typically produce a very unsettling sensation of being cut off entirely from the Force, which has caused many a wearer to panic. Additionally extended wearing of the collar for several months will begin to cause the wearer to actually lose the ability to use the Force, in rare cases permanently. Chemical collars are typically more effective than electric or ultrasonic Force collars, especially for those with strong ties to the Force, since they actually degrade the wearer's ability, not just block it. Chemical Force collars are banned in some systems due to their detrimental effect on the wearers. One cartridge holds 14mg of medication, or enough for 1 week typically, depending on amount of delivered dosage. The collar itself costs only around 500-700 credits, however each vial of medication can cost as much as 1,000-5,000 credits, depending on the exact type used. All forms of medications used are considered at least Class II neurological poisons, and prolonged contact is generally to be avoided.


Reactive collars work by detecting Force artificial disturbances (i.e. those caused by the wearer) and tricking the wearer's body to also producing a counter wave which cancels out the initial disturbance. For example if the wearer were to attempt to Force-push someone, the collar would detect this and interface with the user's Force ability and instruct their cells to create another wave (i.e. pull) equal and opposite to their push. For this reason these collars are extremely effective at controlling Force users quickly without regard to the wearer's ability. These collars also have no side effects from extended wear, unlike chemical Force collars, since the ability to control the Force is not being directly injured from the use of drugs. The downside to these collars is that they are extremely energy-greedy, and the more the wearer attempts to use the Force the more power the collar must expend to issue counter waves. For this reason it is extremely advisable if using this type of collar to carry extra energy packs, or use it in addition to a backup energy or ultrasonic Force collar. Reactive Force collars also can produce a feeling of being 'cut-off' from the Force, since in effect they create a Force-neutral zone for the wearer. This 'cut-off' sensation is typically not as dramatic as that felt by those wearing chemical collars, since the Force-controlling centers remain intact. Reactive Force collars are the most sophisticated form of Force collars and carry a price tag to match, ranging from 5,000-10,000 credits for the collar and 9,000-12,000 for each spare power-cell. Reactive Force collars are safe and effective in all operating environments, however are more sensitive to shock and jarring than other collars. The initial reactive Force collars were designed by the engineering genius Sphinx. She still creates the most reliable models of this sort, and also the most expensive.
