接著請參閱圖8，為本發明一實施例之應用於具備球體外型之小型化近場通訊裝置的穿戴式裝置示意圖。圖8示例一種供戴於脖子或手腕處的穿戴式裝置，包含：具備球體之殼體100外型的小型化近場通訊裝置、複數珠體130、及串接單元500。可同時參閱圖4至圖6，小型化近場通訊裝置的容置腔可藉由殼體100之殼壁定義出一球形腔體，感應天線200係沿殼體100之殼壁環繞。該小型化近場通訊裝置內之近場通訊模組的下方，係為近場感應的方向。感應天線200堆疊的高度H可配置為約3公厘，感應天線200的線徑約為0.15公厘。
Next, please refer to FIG. 8 , which is a schematic diagram of a wearable device applied to a miniaturized near field communication device having a spherical shape according to an embodiment of the present invention. FIG. 8 illustrates a wearable device to be worn on the neck or wrist, including: a miniaturized near field communication device in the shape of a
在圖8的示例中，小型化近場通訊裝置的球體具有約1.5公分的直徑，該小型化近場通訊裝置內之感應天線於一平面上的圍繞面積係約為1.3平方公分，螺旋堆疊的感應天線則可被配置為具有至少15匝的匝數。此外，亦可在殼體100外打印標示150，標示出近場感應方向(可同時參閱圖4之軸心Z)，便於導引使用者以該側進行感應。
In the example of FIG. 8 , the sphere of the miniaturized near field communication device has a diameter of about 1.5 cm, the surrounding area of the induction antenna in the miniaturized near field communication device on a plane is about 1.3 cm2, and the spirally stacked The inductive antenna may then be configured to have a number of turns of at least 15 turns. In addition, a
所述「約」係指具有所述之數值在2%內的差異程度，而在此範圍「+2%~-2%」內的配置。 The "about" refers to a configuration that has a degree of difference within 2% of the stated value, and is within the range of "+2% to -2%".
綜合上述，本發明之實施例中示例出在小型化的近場通訊裝置內可進行的配置，藉由感應天線、近場通訊模組的配置關係及感應天線結構的布置，可增進感應效能，進一步更可讓被動式感應的無源NFC標籤能被應用在穿戴式裝置上。 In view of the above, the embodiments of the present invention illustrate configurations that can be performed in a miniaturized near-field communication device. The sensing performance can be improved by the configuration relationship of the sensing antenna, the near-field communication module, and the arrangement of the sensing antenna structure. Further, passive sensing of passive NFC tags can be applied to wearable devices.
