There are two distinct regulatory requirements for the consent process. First, specific elements of consent must be included in the consent process. Secondly, the consent process must be documented with a signed consent form unless specific criteria are met. If you wish to not include a specific element of consent, or feel you shouldn't obtain consent at all, you should request a waiver of consent from the IRB. If you will have some type of consent process, but will not ask participants to sign a consent form, you should request a waiver of documentation of consent.
