The phrase "activation area" is correct and usable in written English.
It can be used in contexts related to technology, biology, or any field where a specific area is designated for activation or initiation of a process.
Example: "The activation area of the device must be clearly marked to ensure proper usage."
Alternatives: "activation zone" or "trigger area".
Their activation area is pretty small, but I almost never had to look to hit the correct button.
In this paper, we present adaptive activation-area menus (AAMUs), a technique to improve cascading menu performance by providing a localized triangular activation area between the menu and the child submenu.
ΔCFS for 2.5 years ranges from 0.0 to +0.002 MPa in the activation area and from −0.15 to 0.0 MPa in the quiescence area.
The diencephalon-hypothalamic region seems to be an activation area specific to CH, and for this reason, the possible role of attack generator centres has been suggested.
We find that the hypocenters within the volume of the activation area (Anomaly 1) appear to be located along the serpentine boundary (Fig. 11(b)).
Therefore, if the activation area detected in the present study had been close to failure, small ΔCFS can trigger some earthquakes and, thus, the seismicity increases.
Nine activation areas were found in response to undertaking either observation or imitation CSL tasks and three activated areas were found only when undertaking the imitation task.
Activation areas are, in the 400 μm foam, similar to those of the dense constituent metal for both 99.99% pure Al and Al 5 wt.% Mg.
The velocity stress dependence of screws has been measured at the scale of a single dislocation source, and compared with macroscopic activation areas.
Activation areas at each of three plastic strain amplitudes, Δεp/2=0.2, 0.4, and 0.6%, have initial values of approximately 2000b2 which decrease to 600b2 during cyclic loading to saturation.
Moulton et al. found that the cerebellar activation areas overlapped with both unpleasant picture viewing and heat pain in healthy subjects and suggested that the cerebellum may have specific areas associated with encoding of generalized aversive processing [32].
