19 Internet of Things and Wireless Technologies terms
accelerometer
noun
an instrument for measuring the acceleration of a moving or vibrating body.
Example: As soon as a motion series is detected, the
accelerometer generates an interrupt to the MPU which then
activates the main system functions
bristles
noun
a stiff animal hair, or a man-made substitute, used to make a brush.
Example: Brush these areas
with vertical movement of the toothbrush bristles
buccal
adjective
relating to the cheek.
Example: The labial and buccal surfaces are
sides of the teeth that are adjacent to the inside of the lips
or the cheek.
calibration
noun
the action or process of calibrating something.
Example: The architecture of the calibration model is carefully devised to reduce training efforts and facilitate parameter updating with little human intervene.
convective
noun
the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.
Example: This is because the convective boundary layer of a standing person in quiet ambient air is within 1m in diameter
ferromagnetic
adjective
(of a body or substance) having a high susceptibility to magnetization, the strength of which depends on that of the applied magnetizing field, and which may persist after removal of the applied field. This is the kind of magnetism displayed by iron, and is associated with parallel magnetic alignment of neighbouring atoms.
Example: Single Coil - it consists of an induction coil, with ferromag-
netic core, attached on the frame in close proximity to magnets
placed on the rear wheel rim (≈ 2 ÷ 3 mm). 48 rectangular
magnets (40x10x5 mm) are used to fill completely the rim (for
a circumference of ≈ 2.13 m).
fidelity
noun
the degree of exactness with which something is copied or reproduced.
Example: W-Air adopts a sensor-fusion calibration scheme to recover high-fidelity ambient pollutant concentrations from the human
interference.

geo-aware
Location awareness
Example: In this paper, we present a new IoT so-
lution that implements such an infrastructure for a wide range
of bicycle fitness profiling and geo-aware applications
geomagnetic
noun
Earth's magnetic field
Example: In our observation, we find that
the geomagnetic field has a varying magnitude depending
on locations, and its value can go up to more than 100 μT
gingival
adjective
concerned with the gums.
Example: Without proper brushing, such
bacteria accumulate on the tooth surfaces in a complex called
plaque, destroying the outermost layer of the tooth (enamel)
and initiating gingival inflammation, resulting in dental de-
cay and gum diseases
heterogeneity
noun
the quality or state of being diverse in character or content.
Example: Due to the complex heterogeneity of air pollutants and the diverse moving patterns of individuals, personal air pollution sampling is necessary for meaningful personal exposure analysis.
impedance
noun
The effective resistance of an electric circuit or component to alternating current, arising from the combined effects of ohmic resistance and reactance.
Example: BQ25570 - manufactured by Texas Instruments, this IC
is specifically designed to harvest μW to mW of power from
high impedance direct current (DC) sources.
labial
adjective
relating to the lips.
Example: The labial and buccal surfaces are
sides of the teeth that are adjacent to the inside of the lips
or the cheek.
microclimate
the climate of a very small or restricted area, especially when this differs from the climate of the surrounding area.
Example: Nakayoshi et al. [ 28] investigate outdoor thermal physiology by deploying wearable sensors
to record individual microclimate (temperature, humidity, wind speed and radiation) and psychological states
(skin temperature, heart rate).

morphology
noun
the study of the forms of things.
Example: Project ESUM studies the impact of urban morphology on citizens’ social potential (e.g., perception).
quasi-continuous
adjective
having some characteristics of a continuous function, system etc.
Example: Personal air pollution monitoring for quantitative health and well-being applications requires
accurate, convenient, quasi-continuous collection of heterogeneous data.
B. Maag, Z. Zhou, and L. Thiele, “W-air,” Proceedings of the ACM on Interactive, Mobile, Wearable and Ubiquitous Technologies, vol. 2, no. 1, pp. 1–25, 2018.
transducers
noun
a device that converts variations in a physical quantity, such as pressure or brightness, into an electrical signal, or vice versa.
Example: Based on available research work [21]–[25] electromagnetic vibration energy transducers working on the Faraday’s law induction
principles are considered as the most feasible solution that meets all of the above-mentioned application requirements.

Ubiquitous
adjective
present, appearing, or found everywhere.
Example: Human-centered computing → Ubiquitous and mobile computing systems and tools;

Univariate
Adjective
involving one variate or variable quantity.
Example: Univariate linear regression techniques such as ordinary least squares are commonly applied if the sensor is only sensitive to the target pollutant.
