He holds three patents, showcasing his innovative spirit and technical expertise. His work has significantly advanced the capabilities of atomic force microscopy, a vital tool in various scientific research areas.
Latest Patents
One of Peter Maivald's latest inventions is an atomic force microscope featuring a digitally calculated feedback system. This advanced microscope can perform force spectroscopy on samples, allowing researchers to map the local stiffness of materials while also providing detailed topographical information. The device includes a three-dimensional piezoelectric scanner that can either scan the sample or a force sensor. The force sensor is a contact type, equipped with a tip mounted on a cantilever, which detects the deflection of the lever at the tip. The sensor's signal is processed by high-speed digital electronics, controlling the vertical motion of the sample or sensor. During operation, the digital electronics adjust the piezoelectric scanner's height to modulate the force exerted by the tip on the sample. This innovative design enables the measurement of the spring constant of the sample with nanometer spatial resolution, while simultaneously determining the sample's topography with the same precision. An alternate embodiment of the invention allows for the connection of the lever to a separate piezoelectric driver, enhancing the control over the force applied by the tip. This improved atomic force microscope can also periodically reset the contact force and quickly replace the tip if it loses contact with the sample surface.
