The 36-year-old former Republic of Ireland international has made just one appearance for the Potters this season.
"I'd like to think if I do well enough then there'll be something for me here," he told BBC Radio Sheffield.
"I'm out of contract in the summer and I want to keep playing, so I have to prove I can do a job over the next couple of months.
"They've been flying since David (Flitcroft) took over and hopefully they can keep those results going and I'd like to be a part of that.
"This is a great move for me at the moment because I was desperate to get away and play games."
