Everything that Penny has said so far leads me to believe Penny's aura is 100% original. Her own. Not of human origin.

"Most girls are born, but I was made. I'm the first synthetic person capable of generating an aura."

Note she was made, and she "generate[s]" her aura. The wording suggests her aura was created for her and is sustained by her.

Which means one of two things: either Penny has her own, original aura; or she is unaware of her true origin, and believes the former to be the case.
