What it is Filled

The condition of containing or being covered by a liquid, especially water, ranging from damp or moist to soaked; in physics and chemistry the related concept of wetting describes how well a liquid spreads on a surface, measured by the contact angle.

Why it exists Filled

Let an agent describe wetness as a condition, how it is perceived and measured, and the related concepts of wetting and moisture content.

Distinguishing features Filled

  • No dedicated human skin wetness receptor has been identified; perception integrates thermal and tactile cues, with cooling often contributing.
  • Moisture content is a measurable quantity (wet-basis or dry-basis mass fraction, or volumetric); wetness is a condition.
  • Wetting describes the liquid-surface interaction, and contact angle does not measure how much liquid an object contains.

What robots and AI may and may not do Filled

Must not

  • advise using electrical equipment in wet conditions

May

  • describe and explain measurement

Moral aspects Filled

  • safety

Who is affected

  • people in wet environments

Owners Filled

Steward

nobody; a condition

Links to other meta-models Filled

parent

  • oewn-13943868-n - registry parent class

related

  • moisture content - quantity
  • wetting - surface phenomenon
  • humidity - water in air
  • dryness - opposite

What else AI and robots need to interact with it Filled

Identity and identifiers required Filled

  • Vercy registry: vr.tr.wetness
  • Open English WordNet: oewn-14558298-n

Direct properties not applicable Not applicable

  • contact angle (wetting): 0 to 180 degrees - below 90 degrees: the liquid wets the surface

Plane XCT: no invented physical properties.

Recognition optional Filled

  • Darkened or glistening surfaces, droplets or films of liquid
  • A darker, shinier or dripping surface, or a damp feel.

Capabilities and actions required Filled

  • describe degrees of wetness
  • explain how moisture content is measured
  • explain wetting and contact angle
  • explain how humans perceive wetness

Hazards and failure modes required Filled

  • Slips on wet surfaces
  • Mould and rot from persistent dampness
  • Electrical hazards

Standards and interfaces required Filled

  • ISO 15148:2002 water absorption coefficient of building materials by partial immersion
  • IEC 60529 (IP codes) protection against water ingress

Context of use required Filled

  • dampness
  • moistness
  • sogginess and saturation
  • surface wetness
  • leaf wetness (in agriculture)

Sources Filled

  1. wetness - sense of the word
  2. Wetting - wetting and contact angle
  3. ISO 15148:2002 - Exact scope of the partial-immersion water absorption standard.
  4. IEC 60529:1989 - IP Code classification of protection provided by electrical equipment enclosures.
  5. Contact angle - Contact-angle definition, interface convention and advancing, receding and equilibrium angles.
  6. The biology of skin wetness perception and its implications in manual function and for reproducing complex somatosensory signals in neuroprosthetics - No identified human hygroreceptor, thermal and tactile integration, and perception of warm wet stimuli.
  7. Solids Content of Wastewater and Manure - Difference between wet-basis and dry-basis moisture content.
  8. Soil moisture monitoring to support irrigation scheduling - Mass-based and volume-based water content and measurement methods.
