A Synchroniser implant

Crassus held up the toils of the design he had created, just needed to fabricate it now. It worked by changing the signals, allowing the nodules to be synchronised with more precision. If it worked the nodules would sync up and the field produced would be strong enough for practical use... if not... well, the implant could destroy their nervous system and result in their deaths, though it would likely require more fine tuning to the nervous system frequency
