Abstract: The present disclosure relates to an organic electroluminescent compound and an organic electroluminescent device comprising the same. By comprising the compound according to the present disclosure, it is possible to produce an organic electroluminescent device having improved driving voltage, power efficiency, and/or lifetime properties compared to the conventional organic electroluminescent devices.

Abstract: An elastic body for measuring loads and a non-contact load-measuring device are disclosed. The elastic body includes: an elastic body base; a multiple number of slits formed in the elastic body base; and a deforming space part formed in the elastic body base. Inside the deforming space part are formed: a hinge, a first deforming part coupled with the hinge, and a second deforming part that is coupled with the first deforming part and the hinge and is formed with a greater length than that of the first deforming part. The first deforming part and second deforming part are configured to undergo rotational movements about the hinge in correspondence to the load, the first deforming part moving downwards in correspondence to the load and the second deforming part moving upwards in correspondence to the load. The upward displacement of the second deforming part is used for measuring the load.
