The sex androids developed by aircraft mechanic Michael Harriman from Nuremberg have "hearts" that beat harder during sex. They also breathe harder and have internal heaters to raise the body temperature - but their feet stay cold "just like in real life", according to Harriman.
He said: "They are almost impossible to distinguish from the real thing, but I am still developing improvements and I will only be happy when what I have is better than the real thing."
The dolls are on offer for US $7 000 each for the basic model, with extra charges for adaptations like extra large breasts. Underneath the silicon skin, developed for use in medical surgery, is an electronic heart that beats faster during sex. The model can also be made to move by remote control, wiggling her hips under the bedclothes and making other suggestive movements - all at the touch of a button.Harriman said his design was an improvement on the popular "real dolls" sold in the US.
PS: Will he put on a market a male model too?
