Michigan · 0.3 mm microdevice: size, dimension and comparison

The adopted reference is about 300 µm.

side length of the microdevice ≈ 0.3 mm

300 µm = 0.3 mm. A micron (µm) is a millimeter divided by 1,000.

2018Demonstration

In 2018, an experimental device combines computing and sensing at the scale of a tiny grain.

What does this number measure?

In 2018, the University of Michigan announced a microdevice with sides of about 0.3 mm, designed in particular for temperature measurements. The reference compares one side of the complete experimental device, not the length of a transistor. Its power supply and communications rely on light and an external setup; it is not a standalone PC or a miniature replacement for a general-purpose processor. The demonstration shows how reducing a specific function can reach a different scale.

Compare the stated dimensions

The comparison uses the number in each fact sheet: altitude, height, diameter, length or distance, depending on the reference. Two values in metres do not necessarily describe the same property.

Source and limitations

Linked source not consulted: the proxy returns CONNECT403 for this domain during this session. Approximate historical value to be checked again in an accessible source; no measurement of the illustration. The media expression ‘smallest computer’ should not be interpreted as a standalone PC or a current record.

Experimental optical microdevice: the device's side length is compared; internal details are interpreted. This is not a photograph or a miniature personal computer.

Demonstration: 2018. Proposed historical date; an existing documentary source is linked but was not consulted for this date in this session. Do not interpret this reference as the manufacturing date of the illustrated specimen. Experimental optical device with an external station, not a self-contained PC.
