No, "informed" means you have been given information prior to your express consent. Implied consent means your actions imply you consent, whether or not you were ever informed.
For example, a doctor wants to do surgery upon your body and requires INFORMED consent, in writing, to avoid being charged with battery. An EMT finds you unconscious on the ground and has your IMPLIED consent to perform first aid. Similarly, you enter a sports stadium and your presence there implies your consent to their rules including the possibility of being searched for weapons or alcohol.
