圖1為本發明較佳實施例穿戴裝置的整體結構示意圖。
圖2為穿戴裝置的功率調整模組的結構方框圖。
請參閱圖1，本發明公開了一種穿戴裝置100，該穿戴裝置100可為手錶或者手環。
該穿戴裝置100包括主體10、螢幕20，背蓋30和穿戴部40，該螢幕20設置於主體10上方，該背蓋30設置於主體10下方，該穿戴部40設置於穿戴主體10的兩側。在穿戴時，用戶手腕放入穿戴部40內，背蓋30與用戶手腕貼合，螢幕20朝向外側，便於用戶觀察其所顯示的資訊。
請參閱圖2，該穿戴裝置100還包括設置於主體10內的功率調整模組11與射頻天線12。該功率調整模組11包括感測器13與CPU14。該射頻天線12 用於發射/接收射頻訊號。該感測器13用於觸發一感測訊號並發送至CPU14。該CPU14根據該感測訊號判斷所述穿戴裝置100處於穿戴模式或自由模式。若穿戴裝置100處於穿戴模式，則CPU14控制所述射頻天線12增大天線傳導功率；若穿戴裝置100處於自由模式，則CPU14控制所述射頻天線12降低天線傳導功率。
本發明的第一較佳實施例中，該感測器13為重力感測器(G-sensor)，該重力感測器的感測訊號為重力感測器偵測的加速度訊號。當用戶穿戴該穿戴裝置於手腕上時，隨著用戶的運動，該重力感測器將會輸出不同的加速度訊號，該重力感測器將該加速度訊號轉化為電訊號回饋至CPU14，該CPU14根據訊號判斷此時穿戴裝置100處於穿戴模式；當用戶未穿戴該穿戴裝置100於手腕上時，缺少用戶運動的影響，該重力感測器未感測到加速度訊號，沒有加速度訊號回饋至CPU14，該CPU14判斷此時穿戴裝置100處於自由模式。
本發明的第二較佳實施例中，該感測器13為光感測器，該光感測器包括發光二極體和光檢測器，該發光二極體向該穿戴裝置100用戶手腕穿戴處發射光線，光檢測器用於接收該光線的反射光線。當用戶穿戴該穿戴裝置100於手腕上時，用戶手腕遮擋住發光二極體發出的發射光線，光檢測器接收到發射光線經用戶手腕反射的反射光線，該光檢測器將光訊號轉化為電訊號回饋至CPU14，該CPU14根據電訊號判斷此時穿戴裝置100處於穿戴模式；當用戶未穿戴該穿戴裝置100於手腕上時，缺少手腕的影響，該光感測器未感測到反射光，沒有訊號回饋至CPU14，該CPU14判斷此時穿戴裝置100處於自由模式。
本發明的第三較佳實施例中，該感測器13為脈搏波感測器(PPG-sensor)，脈搏波感測器可以為紅外脈搏波感測器或光電脈搏波感測器。以紅外脈搏波感測器為例，該紅外脈搏波感測器包括紅外發光二極體和紅外光敏三極管，紅外發光二極體用於向用戶手腕佩戴處發射紅外光線。當用戶穿戴該穿戴裝置100於手腕上時，用戶手腕遮擋住紅外發光二極體發出的紅外光線， 紅外發光二極體發出的紅外光照射到血管上，部分紅外光經血管反射被光敏三極管接收並轉換成電訊號回饋至CPU14，該CPU14根據電訊號判斷此時穿戴裝置100處於穿戴模式；當用戶未穿戴該穿戴裝置100於手腕上時，缺少手的影響，該光敏三極管未感測到紅外發光二極體發出的紅外光，沒有訊號回饋至CPU14，該CPU14判斷此時穿戴裝置100處於自由模式。
本發明的第四較佳實施例中，該感測器13為心電圖感測器(ECG-sensor)，該心電圖感測器包括電極片，該電極片位於背蓋30上。當用戶穿戴該穿戴裝置100於手腕上時，用戶手腕與背蓋30上的電極片相接觸，該電極片感測用戶手腕處心臟跳動引起的電位變化，該心電圖感測器將動作電位訊號轉化為電訊號回饋至CPU14，該CPU14根據電訊號判斷此時穿戴裝置100處於穿戴模式；當用戶未穿戴該穿戴裝置100於手腕上時，缺少手腕的影響，該心電圖感測器未感測到所述電位變化，沒有訊號回饋至CPU14，該CPU14判斷此時穿戴裝置100處於自由模式。
本發明的穿戴裝置100可使用上述四種感測器13單獨進行檢測或組合檢測。當多個感測器13均判斷為穿戴模式或自由模式，則判斷成立；當出現多個感測器13判斷結果不同時，此時判斷不成立，感測器13重新進行檢測。
本發明的穿戴裝置100，包括主體10，所述主體10內設置有功率調整模組11及射頻天線12，該功率調整模組11包括感測器13、CPU14，所述感測器13將感測訊號傳送至所述CPU14，所述CPU14根據感測訊號判斷所述功率調整模組11處於穿戴模式或自由模式，若處於穿戴模式，則所述CPU14控制所述增大射頻天線12的天線傳導功率，能維持穿戴裝置100良好輻射效果；若處於自由模式，則所述CPU14控制所述功率調整電路15降低射頻天線12的天線傳導功率，能藉由電磁波吸收比值(SAR)的規範。
