Chakra Transmitting Device

 is a technique which stores one's chakra and when activated transmits it and when attached to an object it would cause that chakra to flow all over that particular object. It distributes the chakra equally and proportionately all over a body as such it can be used to fool Sensor's or Sharingan users. Knowing that Sigma Uchiha wields the crimson eye, Takumi used the stored chakra from Shinzui Uchiha to fool him, with both of them being Uchiha's and their chakra's being nearly same in nature. It seems to be capable of preventing chakra loss as seen it contained the exact amount of chakra taken from Shinzui years ago until it was used by Takumi in battle against Sigma.
