图1是主动笔100的示意图。主动笔100可以包括笔尖110和笔杆120，笔杆120与笔尖110相接。其中，根据笔杆120的位置和相应的功能的不同，该笔杆120还包括多个不同的区域。例如，如图1所示，笔杆120可以包括笔握121，该笔握121为使用该主动笔100的用户的握笔区域，该笔握121的大小可以根据实际应用进行设置。再例如，如图1所示，该笔杆120还可以包括笔尾122，笔尾122为笔杆120的端部区域，该笔尾122为与笔尖110相对设置的一端。再例如，如图1所示，该笔杆120还可以包括笔夹123，位于靠近笔尾122的区域，可以用于将该主动笔100与其他设备之间的固定，例如，可以通过该笔夹123将该主动笔100夹持于其他设备上。再例如，如 图1所示，该笔杆120还可以包括按键124，该按键124可以用于控制主动笔100执行相关操作；该笔杆120还可以包括指示灯125，该指示灯125可以通过发光，以指示或者提示用户。
应理解，本申请实施例的主动笔100可以用于具有触摸屏的电子设备，例如，该电子设备可以为笔记本、平板或者智能手机等。带主动笔功能的电子设备，在识别到主动笔100靠近后会主动告知主动笔100，主动笔100可以通过主动打码来告知电子设备自身坐标，从而实现了书写功能；另外，主动笔100还可以带压力检测功能，主动笔100可以同步传输压力数据至电子设备，从而还可以实现不同粗线的笔迹。
具体地，图2示出了电子设备和主动笔配合工作的示意图。如图2所示，电子设备的触摸屏上分布着一定数量的竖直方向和水平方向的检测电极，例如可以是互容式触摸屏的驱动电极和感应电极，分别连接驱动电路和感应电路。主动笔100可以通过位于笔尖110处的电极向外发射打码信号，该打码信号被触摸屏检测后，可以用于计算主动笔100在触摸屏上的坐标，例如，当笔尖110输出的打码信号作用在屏幕的某一位置时，该位置对应的横向电极和纵向电极都会产生相应的检测信号，触摸屏可以通过触摸控制器，根据该检测信号，计算主动笔100在屏幕上的二维位置坐标。另外，笔尖110的电极还可以连接有一个压力传感器。该压力传感器用于检测主动笔100对触摸屏产生的压力，从而可以使主动笔100感测用户书写力度的变化，并使触摸屏根据书写力度的变化来改变笔迹的粗细，达到优异的用户效果体验。
随着各种智能设备的快速发展，个人健康被重视的程度越来越高，如何利用这些智能设备实现更加便捷的自身健康状况监测，已经成为一项亟待解决的技术问题。因此，本申请实施例提供了一种用于触摸屏的主动笔，能够解决上述问题。
图3示出了本申请实施例的主动笔100的示意性框图，该主动笔100可以与具有触摸屏的电子设备结合使用，例如，该主动笔100可以为上述图1中的主动笔100，适用于主动笔100的相关描述，为了简洁，在此不再赘述。
如图3所示，该主动笔100可以包括生物特征检测模组130，该生物特征检测模组130可以设置于主动笔100的笔杆120处，该生物特征检测模组130用于检测使用主动笔100的用户的生物特征，其中，该生物特征可以包括以下至少一种：脉搏、血氧和心电图。
因此，本申请实施例的主动笔100，通过在笔杆120上设置生物特征检测模组130，可以实现使用主动笔100的用户的生物特征的检测，例如，可以检测用户的脉搏、血氧和心电图等，这样，可以为个人健康管理提供更方便、快捷的渠道，实现生物特征的实时监测。
在本申请实施例中，生物特征检测模组130可以通过多种方式，实现用户的生物特征检测，下面将结合附图和具体实施例进行详细介绍。
可选地，如图3所示，该生物特征检测模组130可以包括光电容积脉搏波描记法(Photoplethysmography，PPG)模块131，通过该PPG模块131可以实现用户的脉搏和/或血氧的检测。具体地，图4示出了本申请实施例的主动笔100的另一示意图，如图4所示，本申请实施例的PPG模块131可以设置在主动笔100的内部，例如可以设置在主动笔100的外壳的下方；另外，PPG模块131可以位于笔杆120的笔握121处，例如，PPG模块131可以位于笔握121的中心位置，或者也可以位于笔握121的靠近笔尖110的区域，以使得用户在使用主动笔100时，在握笔时，可以覆盖该PPG模块131，从而进行检测，但本申请实施例并不限于此。
图5示出了本申请实施例的PPG模块131的示意性框图，如图5所示，该PPG模块131可以包括：光源1311和光学传感器1312，其中，该光源1311可以用于发出光信号，该光信号照射用户的手指后会产生返回光信号；该光学传感器1312可以用于接收该返回光信号，该返回光信号可以用于检测用户的脉搏和/或血氧。
应理解，本申请实施例中的光源1311可以采用发光二极管(Light Emitting Diode，LED)，对应的，光学传感器1312可以采用光电二极管(Photo-Diode，PD)，但本申请实施例并不限于此。
可选地，如图5所示，该PPG模块131还可以包括第一基板1313，光源和光学传感器设置于第一基板1313的上表面。例如，该第一基板1313可以为柔性电路板(Flexible Printed Circuit，FPC)，或者，也可以为印制电路板(Printed Circuit Board，PCB)，本申请实施例并不限于此。
在本申请实施例中，该主动笔100还可以包括：第一处理单元1314，该第一处理单元1314可以用于根据光学传感器1312接收到的返回光信号确定用户的脉搏和/或血氧。可选地，如图5所示，PPG模块131可以包括该第一处理单元1314，即该第一处理单元1314集成于PPG模块131中；或者， 该第一处理单元1314也可以不与PPG模块131集成，例如，该第一处理单元1314也可以与主动笔100中的控制芯片集成，但本申请实施例并不限于此。另外，本申请实施例中的第一基板1313可以与该第一处理单元1314连接，以使得该第一处理单元1314可以获取返回光信号。
可选地，本申请实施例的PPG模块131可以用于检测用户的脉搏和/或血氧，或者其他生物特征，例如，可以通过设置光源1311发出不同的光信号，以测量用户的不同的生物特征。为了便于说明，本文以检测用户的脉搏和血氧为例进行说明，但本申请实施例并不限于此。
可选地，对于用户的脉搏的测量，该光源1311可以发出第一光信号，该第一光信号照射手指后对应可以返回第一返回光信号，该第一返回光信号可以用于测量用户的脉搏。例如，图6示出了本申请实施例的PPG模块131的俯视图，如图6所示，光源1311可以包括第一光源1311a，第一光源1311a可以用于发出第一光信号，例如，该第一光信号可以为绿色光信号。
可选地，对于用户的血氧的测量，该光源1311可以发出第二光信号和第三光信号，与第二光信号对应的为第二返回光信号，与第三光信号对应的为第三返回光信号，第二返回光信号和第三返回光信号的差异用于检测用户的血氧。例如，如图6所示，该光源1311可以包括第二光源1311b和第三光源1311c，第二光源1311b用于发出第二光信号，第三光源1311c用于发出第三光信号。例如，第二光信号可以为红色光信号，第三光信号可以为红外光信号。
具体地，如图6所示，光源1311包括的三种不同的光源以及光学传感器1312可以采用图6所示的方式设置在第一基板1313的上表面，或者，也可以采用其他方式排列。其中，对于第一光源1311a至第三光源1311c中的每种光源，分别可以设置一个或者多个，并且可以根据实际应用设置其分布的位置，以使得光学传感器1312可以接收到对应的返回光信号。例如，以图6中光学传感器1312位于中心区域为例，图6中设置有两个第一光源1311a，该两个第一光源1311a分别位于光学传感器1312的两侧，例如可以对称分布，这样使得两个第一光源1311a产生的光分布更加均匀；而图6中的第二光源1311b和第三光源1311c各设置一个，并位于该光学传感器1312的一侧，从而使得第二光源1311b和第三光源1311c产生的光信号的光路基本一致，但本申请实施例并不限于此。
应理解，本申请实施例的PPG模块131可以采用一体式镜片的方式，或者也可以采用独立式镜片的方式进行设置。
对于独立式镜片的方式，图7示出了图6中PPG模块131沿A-A’方向的剖视图，图8示出了图6中PPG模块131沿B-B’方向的剖视图。如图6至图8所示，在第一光源1311a至第三光源1311c的上方以及光学传感器1312的上方分别设置有相互独立的镜片1315，以使得三个光源发出的光信号可以通过该镜片1315照射至使用主动笔100的用户的手指或者手，从而产生返回光信号，该返回光信号再经过镜片1315后传输至光学传感器1312。可选地，本申请实施例的多个镜片1315中每个镜片1315还可以为其他透明介质，例如，该镜片1315可以替换为通孔，本申请实施例并不限于此。并且，各个镜片1315之间还可以设置有支架1316，以用于支撑该PPG模块131，具体地，该支架1316可以用于支撑多个镜片1315，也可以用于支撑第一基板1313与其他部件。
而对于一体式镜片的方式，图9示出了图6中PPG模块131沿A-A’方向的另一剖视图，图10示出了图6中PPG模块131沿B-B’方向的另一剖视图。如图6和图9-10所示，在第一光源1311a至第三光源1311c的上方以及光学传感器1312的上方设置有一体式的镜片1315，相比于独立式镜片的设置方式，一体式镜片1315加工更加方便。其中，一体式镜片设置方式中的该镜片1315可以为任意透明材质，并且可以通过支架1316将该镜片1315固定于第一光源1311a至第三光源1311c的上方以及光学传感器1312的上方。可选地，支架1316与镜片1315之间可以通过固定胶进行固定，这样，镜片1315上与支架1316对应的区域为非透明区域1315b。相反的，如图6和图9-10所示，在第一光源1311a至第三光源1311c的上方以及光学传感器1312的上方，对应于镜片1315的透明区域1315a，三个光源发出的光信号可以通过该透明区域1315a照射至使用主动笔100的用户的手指或者手，从而产生返回光信号，该返回光信号再经过透明区域1315a后传输至光学传感器1312。
应理解，镜片1315的非透明区域1315b可以为与支架1316对应的区域，而透明区域1315a可以为镜片1315中除非透明区域1315b外其他区域的全部或者部分区域；或者，镜片1315的透明区域1315a可以为镜片1315中分别与第一光源1311a至第三光源1311c以及光学传感器1312对应的区域， 而非透明区域1315b为镜片1315中除透明区域1315b外其他区域的全部或者部分区域。例如，如图9和图10所示，镜片1315的非透明区域1315b为与支架1316对应的区域，而透明区域1315a可以为镜片1315中分别与第一光源1311a至第三光源1311c以及光学传感器1312对应的区域，即透明区域1315a为镜片1315中除非透明区域1315b外其他区域中的部分区域，但本申请实施例并不限于此。
图11示出了本申请实施例的通过绿色光信号进行用户的脉搏检测的原理的示意图，如图11所示，第一光源1311a发出第一光信号，透射至使用主动笔100的用户的手指后，产生第一返回光信号，光学传感器1312接收该第一返回光信号，该第一返回光信号可以用于确定用户的脉搏或者心率。具体地，考虑到人体脉搏跳动时，血管内血液含量会随之变化，而血液对绿色光吸收较多，所以若第一光源1311a发出绿色光信号，那么随着血流量的变化，对应光学传感器1312接收的第一返回光信号的强度与血流量呈反比变化，即血管内血液越多，光学传感器1312接收的第一返回光信号的强度越弱，也就是PPG模块131测量的PPG信号越弱，从而可以测量用户的脉搏或者心率。
图12示出了示出了本申请实施例的通过红色和红外光信号进行用户的血氧检测的原理的示意图，如图12所示，第二光源1311b发出第二光信号(如图12中白色线段和白色尖头所示)，同时，第三光源1311c发出第三光信号(如图12中黑色线段和黑色尖头所示)，第二光信号透射至使用主动笔100的用户的手指后，产生第二返回光信号，第三光信号透射至使用主动笔100的用户的手指后，产生第三返回光信号，其中，第二光源1311b和第三光源1311c通常并列设置，以使得二者产生的光信号的光路相近；光学传感器1312接收该第二返回光信号和第三返回光信号，则该第二返回光信号和第三返回光信号可以用于确定用户的血氧，例如，可以通过同时测量的两个光源产生的光信号在经过相似的光路后返回的第二返回光信号和第三返回光信号，根据该第二返回光信号和第三返回光信号的差，确定用户的血氧含量。具体地，考虑到随着人体脉搏跳动，血管内血液含量也会随之变化，而血液中血球蛋白等对红色光或者红外光的吸收较多，所以若第二光源1311b和第三光源1311c分别发出红色光信号和红外光信号，那么随着血流量的变化，对应光学传感器1312接收的第二返回光信号和第三返回光的强度与血 液中的血球蛋白等呈反比变化，即血液中血球蛋白等含量越多，光学传感器1312接收的第二返回光信号和第三返回光信号的强度越弱，也就是PPG模块131测量的红色光信号对应的PPG信号(如图12中PPG信号中虚线所示)越弱，红外光信号对应的PPG信号(如图12中PPG信号中实线所示)也越弱，从而可以根据二者差异测量用户的血氧含量。
应理解，本申请实施例中的PPG模块131可以设置在主动笔100的外部壳体的下方，考虑到第一光源1311a至第三光源1311c发出的光信号需透射至使用该主动笔100的用户的手指以产生返回光信号，因此，主动笔100的外部壳体上与该PPG模块131对应的区域应设置为透光区域，或者说，外部壳体上与三个光源和光学传感器1312对应的区域应设置为透光区域。例如，可以将该主动笔100的笔握121的外部壳体的局部设置为透明介质，并在该透明处下方设置该PPG模块，以使得第一光源1311a至第三光源1311c发出的光信号能够透过该透明的壳体区域后照射至使用该主动笔100的用户的手指上。或者，也可以将该PPG模块131作为该主动笔100的外部壳体的一部分，以使得用户的手指可以直接触摸该PPG模块131的表面，这样，PPG模块131上的第一光源1311a至第三光源1311c发出的光信号也可以透射至手指内，本申请实施例并不限于此。
应理解，由于PPG模块131为光检测原理，因此容易受外部环境光的影响，为了能够降低环境光的干扰，PPG模块131中的上述三个光源可以分别采用不同的调制频率发射光信号，例如，该PPG模块中还可以包括调制电路，以使得三个光源采用不同的调制频率发光，对应的，光学传感器1312接收的返回光信号进行相应频率的解调。这样，由于环境光大部分能量位于低频或直流区域，因此，通过频率调制，例如采用较大频率发射光信号，可以很好的避开环境光的影响，提高检测的精确度。
应理解，上文中以PPG模块131为例，详细介绍了通过PPG模块131测量用户的脉搏和血氧的过程，与之不同的，也可以采用其他装置和方式，通过主动笔100测量用户的脉搏和血氧，本申请实施例并不限于此。
可选地，如图3所示，该生物特征检测模组130还可以包括心电图仪(Electrocardiograph，ECG)模块132，该ECG模块132可以用于确定用户的心电图。具体地，本申请实施例中的ECG模块132可以采用单导联，图13示出了本申请实施例的ECG模块132的示意性框图，如图13所示，该 ECG模块132可以包括第一导联电极1321和第二导联电极1322，其中，第一导联电极1321用于在用户的一只手触摸时产生第一电信号；第二导联电极1322用于在用户的另一只手触摸时产生第二电信号，该第一电信号和第二电信号用于生成用户的心电图。
在本申请实施例中，该主动笔100还可以包括：第二处理单元1323，该第二处理单元1323可以用于根据第一电信号和第二电信号，生成用户的心电图。可选地，如图13所示，该ECG模块132可以包括第二处理单元1323，即该第二处理单元1323集成于ECG模块132中；或者，该第二处理单元1323也可以不与ECG模块132集成，例如，该第二处理单元1323也可以与主动笔100中的控制芯片集成，但本申请实施例并不限于此。
应理解，如图4所示，考虑到用户使用主动笔100时的姿势，ECG模块132包括的两个导联电极可以分别设置在笔杆120的笔握121处和笔尾122处，例如，第一导联电极1321位于主动笔100的笔握121处，第二导联电极1322位于主动笔100的笔尾122处。在需要检测心电图时，用户右手握笔，右手手指按压第一导联电极1321，左手手指尖端压住第二导联电极1322处；或者左手握笔，左手手指按压第一导联电极1321，右手手指尖端压住第二导联电极1322处，通过两只手产生的电信号，检测用户的心电图。
如图4所示，考虑到主动笔100通常为圆柱体，笔握121处的第一导联电极1321可以对应设置为管状，以环绕笔握121位置。具体地，图14示出了本申请实施例的第一导联电极1321的截面图，如图14所示，第一导联电极1321可以包括第一电极1321a和第二电极1321b，第一电极1321a和第二电极1321b环绕主动笔100的笔握121处，并且，第一电极1321a和第二电极1321b之间做绝缘处理。而位于笔尾122处的第二导联电极1321可以根据实际应用设置为任意形状，例如，可以设置为圆形或者矩形，本申请实施例并不限于此。
对于ECG模块132中的任意一个电极，可以采用膜内一体式注塑工艺或者胶水贴合工艺进行安装，或者也可以采用其它方式安装。以第一导联电极1321的安装方式为例，图15示出了本申请实施例的采用胶水贴合工艺安装的第一导联电极1321的截面示意图，图16示出了本申请实施例的采用膜内一体式注塑工艺安装的第一导联电极1321的截面示意图。
如图15所示，在采用胶水贴合工艺安装第一导联电极1321时，第一导 联电极1321可以通过胶水1324固定在支架1325的表面，例如，可以在支架1325的表面设置凹槽，通过胶水1324将第一导联电极1321固定在凹槽内。如图15所示，第一导联电极1321还通过导电弹片1326与第二基板1327电连接，例如，可以将第二基板1327设置在支架1325的下方，导电弹片1326穿过支架1325后与第二基板1327连接。
如图16所示，在采用膜内一体式注塑工艺安装第一导联电极1321时，可以在支架1325的一个表面上设置第一凹槽，该第一凹槽内设置第一导联电极1321，相对的，在支架1325的另一个表面上设置第二凹槽，该第二凹槽内设置第二基板1327，并且，导电弹片1326穿过支架1325，以实现第一导联电极1321与第二基板1327的电连接。
应理解，本申请实施例中的支架1325和第二基板1327的形状可以根据第一导联电极1321的形状设置，例如，图15和图16中以第一导联电极1321为片状结构为例，对应支架1325和第二基板1327也为片状。当本申请实施例中的第一导联电极1321为如图14所示的管状结构时，对应的支架1325与第二基板1327也可以设置为管状或者圆柱体，并且将支架1325和第二基板1327设置在管状的第一导联电极1321的内部，本申请实施例并不限于此。
类似的，本申请实施例的第二导联电极同样可以采用图15所示的胶水贴合工艺安装，或者采用如图16所示的膜内一体式注塑工艺安装。
另外，考虑到在进行心电检测时，用户的两只手分别按压ECG模块132的两个导联电极以产生电信号，即用户的手指需直接触摸两个导联电极，因此，位于笔握121处的第一导联电极1321设置为主动笔100的外部壳体的一部分，以使得使用该主动笔100的用户在握笔时可以直接触摸该第一导联电极1321；类似的，位于笔尾122处的第二导联电极1322设置为主动笔100的笔尾122处的外部壳体的一部分，以使得用户的手指可以直接触摸该第二导联电极1322。
在本申请实施例中，该第二基板1327可以为FPC板或者PCB板，本申请实施例并不限于此。并且，本申请实施例中的第二处理单元1323与同第一导联电极1321电连接的第二基板1327电连接，以获得通过该第一导联电极1321采集的电信号，同时，第二处理单元1323也与同第二导联电极1321电连接的第二基板1321电连接，以获得通过该第二导联电极1322采集的电信号，从而使得该第二处理单元1323可以根据采集到的电信号确定心电图。
应理解，根据实际主动笔100的需要，主动笔100可以仅包括PPG模块131或者ECG模块132，或者也可以同时具有PPG模块131和ECG模块132，或者也可以将PPG模块131或者ECG模块132与其他进行生物检测的模块结合使用，本申请实施例并不限于此。
因此，本申请实施例的主动笔100，在笔杆120上设置生物特征检测模组130，可以实现使用主动笔100的用户的生物特征的检测，例如，主动笔100可以设置有PPG模块131，以检测脉搏数和血氧数据，PPG模块131可以发射绿光，用来监测脉搏数据，发射红色及红外光，用于监测血氧数据；主动笔100上还可以采用ECG模块132监测心电图，ECG模块132的电极可以采用单导联，通过笔握121和笔尾122上设置的两个导联电极检测电信号，进而生成心电图。具体地，用户在握笔写字时，以右手握笔为例，右手手指部分会遮住PPG模块131，也会触摸到ECG模块132的一个导联电极1321，此时可以自动完成脉搏和血氧的数据监测，如果需要采集完整的心电图，还需要用户的左手指尖压住笔尾122的第二导联电极1322，ECG模块132可以在身体出现不适时第一时间获取瞬间异常心电，辅助心率变异性和房颤分析，第一时间提醒用户注意休息。
在通过主动笔100检测到用户的生物特征后，还可以根据生物特征检测结果，进行进一部处理。具体地，图17示出了本申请实施例的检测用户的生物特征的方法200的示意性流程图。该方法200可以用于本申请实施例中的主动笔100，例如，如图3所示，该主动笔100还可以包括处理模块140，该方法200可以由主动笔100中的该处理模块140执行。
具体地，如图17所示，该方法200还包括：S210，通过生物特征检测模组130检测使用主动笔100的用户的生物特征，该生物特征包括以下至少一种：脉搏、血氧和心电图；S220，根据生物特征检测模组130检测的数据，确定生物特征的检测结果；S230，根据生物特征的检测结果确定生物特征是否异常。
可选地，在S210中，生物特征检测模组130可以通过PPG模块131检测用户的脉搏和/或血氧，还可以通过ECG模块132检测用户的心电图，进而在S220中，由处理模块140确定用户的生物特征的检测结果，例如，该生物特征的检测结果可以包括用户的脉搏跳动速度、血氧含量以及心电图中的至少一个。
在本申请实施例中的，在S230中，处理模块140可以确定用户的生物特征是否异常。例如，当用户的脉搏跳动速度过大或者过小，例如大于第一阈值或者小于第二阈值时，可以确定该生物特征出现异常；再例如，当用户的血氧含量过高或者过低时，也可以确定用户的生物特征出现异常；再例如，当用户的心电图显示异常心电，出现心率变异性和房颤时，也可以确定用户的生物特征出现异常，本申请实施例并不限于此。
进一步的，若处理模块140确定用户的生物特征出现异常，可以通过多种方式提示用户。可选地，该方法200还可以包括：若生物特征异常，控制主动笔100的指示灯125按照预设模式闪烁。具体地，该预设模式可以包括：控制指示灯125发出特定颜色的光，例如，控制指示灯125发出红色的光；该预设模式还可以包括：控制指示灯125按照预设频率闪烁，例如，控制指示灯125按照预先设定的频率闪烁，或者，也可以根据生物特征异常的严重程度，设置不同的频率，但本申请实施例并不限于此。
可选地，该方法200还可以包括：若生物特征异常，控制主动笔100的笔迹颜色变为预设颜色，例如，该预设颜色可以为红色，或者也可以设置为其他颜色，例如，可以由用户选择任一颜色。具体地，当处理模块140确定生物特征异常，可以控制主动笔100的笔迹颜色变为红色，并且，还可以针对生物特征异常的严重程度，使得笔迹的颜色显示为不同程度的红色或者不同粗细的红色，例如，心跳刚超过预设值时，笔迹变为浅红色，而随着心跳越来越快，该笔迹的红色可以越来越深，也可以越来越粗，这样，用户可以通过笔迹颜色和粗细判断个人现在的身体状况，适当休息。
可选地，该方法200还可以包括：处理模块140向电子设备发送用户的生物特征的检测结果，以使的用户可以在电子设备上随时查看自己的生物特征的检测结果，了解用户的健康状况。具体地，如图3所示，主动笔100还可以包括通信模组150，该通信模组150可以用于与对应的电子设备进行通信，例如，该通信模组150可以具有接收模块和发送模块，以与电子设备进行双向通信，例如，主动笔100与电子设备之间可以采用蓝牙的方式进行通信。
在本申请实施例中，该处理模块140可以通过通信模组150向电子设备发送用户的生物特征的检测结果。进一步的，若所述生物特征异常，该处理模块140还可以向该电子设备发送指示信息，以使该电子设备根据该指示信 息向用户显示提示消息。具体地，处理模块140可以通过通信模组150向电子设备发送指示信息，电子设备根据该指示信息确定用户生物特征异常，进而可以通过触摸屏向用户显示提示消息，以提醒用户当前的身体状况需要休息。
