Patent number: 10033106Abstract: A transdermal antenna may be partially inserted into a cavity in the body of a mammal to receive wireless data transmissions from devices located within the body and relay the data to devices located outside of the body. The transdermal antenna may include a first antenna which may be inserted inside of the body cavity and receive radio frequency data transmissions from devices located inside the body. The transdermal antenna may conduct the received data transmissions to a relay mechanism located outside of the body using coaxial cables, waveguides or a combination of both. The relay mechanism may relay the conducted data transmissions to a receiver device located outside of the body by using a wire connection, such as a coaxial cable, or a wireless communication link via a transceiver coupled to a second antenna.Type: GrantFiled: October 3, 2010Date of Patent: July 24, 2018Assignee: Hadasit Medical Research Services & Development Ltd.Inventors: Noam Livneh, Yoav Mintz, Vered Bar-Bracha, Arik Bracha
