Sensors convert information from the environment into interpretable electrical signals. One example of a micromachine sensor is a resonant chemical sensor. A lightly damped mechanical object vibrates much more at one frequency than any other, and this frequency is called its resonance frequency.
The term MEMS, for Micro Electro Mechanical Systems, was coined in the 1980s to describe new, sophisticated mechanical systems on a chip, such as micro electric motors, resonators, gears, and so on. Today, the term MEMS in practice is used to refer to any microscopic device with a mechanical function, which can be fabricated in a batch process ...
An example is a sensor having a switch approximately 1.5 nanometers across, able to count specific molecules in the chemical sample. The first useful applications of nanomachines may be in nanomedicine. For example, [9] biological machines could be used to identify and destroy cancer cells.
An example of a successful machine learning locomotion being used in navigation is by Zou et al. where it was inspired by microorganisms having the ability to naturally switch between locomotory gaits such as a run-and-tumble or a roll-and-flick motion depending on the need to navigate the environment. [195] The artificial intelligence system ...
Antonie van Leeuwenhoek (1632–1723). The field of microscopy (optical microscopy) dates back to at least the 17th-century.Earlier microscopes, single lens magnifying glasses with limited magnification, date at least as far back as the wide spread use of lenses in eyeglasses in the 13th century [2] but more advanced compound microscopes first appeared in Europe around 1620 [3] [4] The ...
MEMS microcantilever resonating inside a scanning electron microscope Proposal submitted to DARPA in 1986 first introducing the term "microelectromechanical systems". MEMS (micro-electromechanical systems) is the technology of microscopic devices incorporating both electronic and moving parts.

Molecular motors are natural (biological) or artificial molecular machines that are the essential agents of movement in living organisms. In general terms, a motor is a device that consumes energy in one form and converts it into motion or mechanical work ; for example, many protein -based molecular motors harness the chemical free energy ...
