A simple design is proposed for an atomic force microscope where the force of interaction between the tip and the surface of the sample is recorded directly using the piezoceramic of an xyz-manipulator. The force signal is used as a feedback signal to keep the gap between the tip and the surface constant, and its electrical conductivity is recorded at the same time.
