Nanomecánica

How do you weigh an atom? How do we measure the interactions between molecules? What do gravitational waves between galaxies have in common with atomic scales? Can robots smell? This work takes a brief tour of the beginnings of nanomechanics, with the construction of the first tunnel-effect microscope and the subsequent development of the atomic force microscope, which led to the study of microlevers, which was the formal birth of this branch of nanotechnology. Starting from the idea of ??sensor and its different types (optical, electrical, mechanical sensors and biosensors), the text reviews the ways in which we can observe the nanometric world and interact with it through examples and experiments, and the revision of concepts essential physics such as resonance, harmonic oscillator or precision, among others. From the photodetectors that regulate the brightness of the screens of our mobiles to the interferometers for the detection of gravitational waves, nanomechanics, despite what its name indicates, does not remain only in the small things.
