Micromobility

Micromobility is the use of small, lightweight, low-speed vehicles, either nonelectric or electric, including bicycles, scooters, mopeds, and skateboards, for short trips, including shared rental fleets.

Micromolding

Micromolding is a microfabrication technique that replicates features from 1 to 1,000 μm into polymers against a precision mold, achieving tolerances of 0.01–5 μm for microfluidic and microelectromechanical applications.

Micromorph tandem solar cell

A micromorph tandem solar cell is a thin-film silicon photovoltaic device stacking an amorphous silicon top cell over a microcrystalline silicon bottom cell, introduced in Switzerland in 1994.

Micromouse

Micromouse is a robotics competition, hosted by the IEEE and others, in which fully autonomous robots explore an unknown 16 × 16 maze and race to its center.

Micron Technology

Micron Technology is an American semiconductor company headquartered in Boise, Idaho, founded in 1978, that makes memory and storage products including DRAM and NAND flash.

Micronization

Micronization is a materials processing technique that reduces solid particles to micrometer and sub-micrometer sizes, most often by dry jet milling, to improve dissolution and solubility.

MicroPets

MicroPets (マイクロペット) is a series of palm-sized pet robots made by the Japanese toy company Takara Tomy, first sold in 2002 and certified by Guinness as the world's smallest voice-activated electric toy.

Micropile

A micropile is a small-diameter, drilled and grouted deep foundation element, typically under 12 inches in diameter, used for underpinning, seismic retrofitting, and slope stabilization.

Microplane

Microplane is a brand of rasp-style kitchen grater with sharp photo-etched teeth, invented in 1990 as a woodworking tool and made by Grace Manufacturing in Arkansas.

Microplastics

Microplastics are solid, water-insoluble plastic particles, generally smaller than 5 mm, that occur throughout the environment and have been detected in food, air, and both bottled and tap drinking water.

MicroPort MedBot

MicroPort MedBot, formally Shanghai MicroPort MedBot (Group) Co., Ltd., is a Chinese surgical robotics company in Shanghai, majority-owned by MicroPort Scientific and known for its Toumai laparoscopic robot.

Microprocessor

A microprocessor is a general-purpose central processing unit on a single integrated circuit or a small set of them, relying on external memory; the first, the Intel 4004, was introduced in 1971.

MicroPython

MicroPython is a lean implementation of Python 3 written to run on microcontrollers and other constrained environments, fitting within 256 KB of code space and 16 KB of RAM.

Microscope

A microscope is an instrument using lenses or electron beams to produce magnified images of objects too small to be seen with the naked eye.

Microscopic Imager

The Microscopic Imager was a fixed-focus camera on the robotic arms of NASA's Mars rovers Spirit and Opportunity, taking extreme close-up views of rocks and soils.

Microscopic traffic simulation

Microscopic traffic simulation is a computational method that models each vehicle on a road network individually, computing its position, speed, and driving decisions second by second.

Microscopy

Microscopy, or microscopic analysis, is the family of techniques for magnifying objects too small to see with the unaided eye, spanning optical, electron, and scanning probe instruments.

Microsemi

Microsemi Corporation was an American semiconductor company in Aliso Viejo, California, known for analog, mixed-signal, and flash-based FPGA products, acquired by Microchip Technology in 2018 for about $8.24 billion.

Microservices

Microservices, also known as microservice architecture, is an architectural style in which an application is built as small, independently deployable services, each owning its own data and communicating through lightweight APIs.

Microsimulation

Microsimulation is a modeling method that simulates individual units one at a time and aggregates results into population-level estimates, proposed by Guy Orcutt in 1957.

Microsoft

Microsoft Corporation is an American technology company in Redmond, Washington, founded by Bill Gates and Paul Allen in 1975 and known for Windows, Azure cloud services, and AI.

Microsoft 365

Microsoft 365 is Microsoft's subscription-based productivity and cloud platform, combining Word, Excel, PowerPoint, and Outlook with cloud services including OneDrive storage, Teams, and Exchange Online email.

Microsoft 365 Copilot

Microsoft 365 Copilot is an AI assistant embedded in Word, Excel, PowerPoint, Outlook, and Teams that drafts and summarizes content, available to commercial customers since November 2023.

Microsoft Access

Microsoft Access, also known as MS Access, is a database management system from Microsoft, first released in 1992, that lets non-specialists build relational database applications on Windows.
