在本发明实施例中，发电单元11例如可以是一个电容。两个电极层11a分别作为该电容的两个电极，两个绝缘层11b则作为该电容中两个电极之间的绝缘电介质。
根据本发明的一个示例，在用户按压发电单元11时，两个绝缘层11b在两者紧密接触的界面上相互摩擦，使两个绝缘层11b各自带有电性相反的静电荷，该电性相反的静电荷分别从所在的绝缘层11b移动至与该绝缘层11b 接触的电极层11a上(即电容被充电)，使得两个电极层11a之间产生电势差，从而电容被充电。在用户停止按压发电单元11时，叠层结构由挤压状态恢复至正常状态，两个绝缘层11b相互摩擦而产生电性相反的静电荷，该电性相反的静电荷分别从所在的绝缘层11b移动至与该绝缘层11b接触的电极层11a上，使得两个电极层11a之间再次产生电势差。
根据本发明的另一个示例，绝缘层还可以是压电材料制成，当用户按压发电单元11时，两个绝缘层11b的压电材料受压而产生电荷，使得两个电极层11a之间产生电势差，电容因此被充电。
由上述内容可知，在本发明实施例提供的便携式生理参数检测装置中，用户反复对发电单元11进行按压，在与发电单元11连接的外电路中产生电流，进而持续为便携式生理参数检测装置充电，从而该装置内部的检测模块20和存储模块30具有电能而工作。与采用的电池等储能有限的储能器件相比，在本发明实施例中，用户能够通过反复按压发电单元11而持续产生电能，而不需要频繁地对储能器件重新充能或更换储能器件，从而能够提高便携式生理参数检测装置的使用便利性。本领域技术人员能够理解，除对发电单元11进行按压外，对发电单元11进行力度适当的推压、摩擦等动作也能够使发电单元11产生电能。
进一步地，由于发电单元中两个绝缘层相互摩擦所能够产生的电量与两个绝缘层相对的接触面积有关，因此，作为本发明实施例的一个优选方案，两个绝缘层相对的表面的形状和大小完全相同，且两个绝缘层按照相对的表面的形状完全对应地紧密接触。通过上述设置，使得两个绝缘层相互接触的面积最大，从而增加两者在摩擦时产生的电量，进而提高便携式生理参数装置的续航能力，最终提高便携式生理参数装置的使用便利性。
此外，在本发明实施例中，由于发电单元11并非一次性储能器件，其能够利用用户活动多次重复地进行摩擦发电，以向检测模块20及存储模块30提供电能，因此，用户无需频繁地对发电单元11进行更换，从而不会因发电单元11的频繁废弃而产生较多的废弃物。且发电单元11通过摩擦发电的物理发电方式产生电能，其中的电极层11a以及绝缘层11b中均不含重金属等污染物质，从而在便携式生理参数检测装置废弃时产生的污染较小。本发明实施例，比之采用化学电池等储能器件更节能环保，因为在使用一次性的储能器件时，用户需要频繁地对该一次性储能器件进行更换，导致产生较多的 废弃物。并且，通常的化学电池等储能器件均含有重金属等多种污染物质，在废弃时产生将造成较大的污染。基于上述原因，本发明实施例提供的便携式生理参数检测装置不会因发电单元11的频繁废弃而产生较多的废弃物，且在便携式生理参数检测装置废弃时产生的污染也相对较小。
按照用户使用方式的不同，在本发明实施例中采用的发电单元11具有两种产生电能的方式。其中一种为：用户主动对发电单元11反复进行按压，使发电单元11产生电能。另一种为：利用用户的日常活动，使发电单元11与其他物体之间自发地产生按压或一定程度的摩擦，进而使发电单元11产生电能。
对于第一种产生电能的方式，可以将发电单元11设置在便携式生理参数检测装置中便于用户按压的位置，并进一步优选对该位置进行标识。例如在将本发明实施例所提供的便携式生理参数检测装置集成在指环上时，可直接使发电单元11的一个电极层11a暴露在指环外部，并在该暴露在外的电极层11a处形成商标等特殊图案。或在该暴露在外的电极层11a处涂装特殊的颜色，使得用户能够简单快捷地找到发电单元11并对其进行按压，进而使发电单元11更高效地产生电能。
而对于第二种产生电能的方式，优选将发电单元11设置在便携式生理参数检测装置中易于与其他物体产生按压或摩擦的位置。例如，在将本发明实施例所提供的便携式生理参数检测装置集成在衣物上时，可将发电单元11设置在衣物的腋下、领口或袖口等易产生按压或摩擦的位置(对于发电单元的个数不做限定)，使发电单元11能够尽可能地利用用户的日常活动，最大限度地产生电能。
由于便携式生理参数检测装置具有便携式的特性，其应用环境通常接近人体，因此，基于便于使用及节约能源的理念，本发明实施例采用上述利用用户活动以使发电单元11产生电能的发电方式。另一方面，用户活动并没有精确的规律，这导致无法确保发电单元11利用用户活动产生的电能能够维持至生理参数信息保存完毕。因此，本发明实施例中的存储模块30可以在意外断电时不会产生数据丢失的存储器件，例如闪存存储器FLASH或相变存储器PCM等，但并不仅限于此，本领域技术人员可根据实际情况采用合适的存储器件作为存储模块30。
对于上述实施方式而言，绝缘层11b通常由高分子材料制成，具体地， 可为聚酰亚胺层、苯胺甲醛层、聚甲醛层、乙基纤维素层、聚酰胺层、三聚氰胺甲醛层、聚乙二醇丁二酸脂层、纤维素层或纤维素乙酸脂层等。可以理解的是，绝缘层11b不限于上述选择范围，在保证发电量足够的前提下，本领域技术人员可以根据实际情况选择其他合适的材料以制备绝缘层。
进一步地，由于相同材料相互摩擦所产生的电荷量小于不同材料相互摩擦所产生的电荷量，因此，根据本发明的一个示例，发电单元11中的两个绝缘层11b的材料不同，使得发电单元11能够输出较大的电量。
对于上述实施方式而言，电极层11a通常由导电性较好且物理性质和化学性质较为稳定的材料制成。例如，电极层11a可为铟锡氧化物层、石墨烯层或银纳米线层。可以理解的是，电极层11a不限于上述选择范围，本领域技术人员可以根据实际情况选择其他合适的材料以制备电极层11a。
如图3所示，根据本发明的一个示例，供电模块10还包括与发电单元11电连接的稳压单元12，稳压单元12用于对发电单元11产生的电压进行稳压调整。在本发明实施例中，稳压单元12可采用稳压电容、稳压二极管、微型稳压器等用于对电压进行稳压调整的微型元器件。通过稳压单元12对发电单元11输出的电压进行稳压调节，使供电模块10输出稳定的电压，使得检测模块20和存储模块30能够在稳定的电压下工作，进而使得便携式生理参数检测装置的使用寿命得到延长。
如图4所示，根据本发明的另一个示例，检测模块20包括：传感单元21，和转换单元22。传感单元21用于对人体进行生理参数检测，并生成用模拟信号表示的生理参数信息。转换单元22，与传感单元21信号连接，用于将用模拟信号表示的生理参数信息转换为用数字信号表示的生理参数信息。本发明所提供的传感单元21可以包括血压传感器、心跳传感器等常见的生理参数测量用传感器。由于这类传感器通常输出模拟信号，而模拟信号在存储和传输的过程中耗费的时间大于对应的数字信号在存储和传输的过程中耗费的时间，因此，在本发明实施例中，通过转换单元22将传感单元21输出的生理参数信息由用模拟信号表示转换为用数字信号表示，以便对生理参数信息进行存储和传输。需要说明的是，由于模拟信号具有较高的保真性，因此在某些需要精确生理参数的应用场景(如高危病易发人群)下，仍需要保留模拟信号表示的生理参数信息。基于上述原因，本领域技术人员可根据实际情况设置合适的生理参数信息的信号类型。
如图5a，图5b所示，根据本发明的一个示例，便携式生理参数检测装置可以通过通信链路与至少一个终端连接。终端例如可以是移动终端、笔记本电脑、平板电脑等电子设备。便携式生理参数检测装置还包括与存储模块30信号连接的传输模块40，传输模块40用于将存储在存储模块30中的生理参数信息传输至上述终端。在该实施例中，通过传输模块40使便携式生理参数检测装置与终端建立通信连接，以将生理参数信息上传至终端。上述通信连接可为有线连接或无线连接(无线连接包括无线相容性认证连接wifi、蓝牙连接、红外线连接或超声信号连接等)。此外，可对应便携式生理参数检测装置，在终端上设置专门的应用软件，利用该应用软件使终端更方便地从便携式生理参数检测装置中获取生理参数信息，并进一步对人体健康状态进行分析、比较和预测。
可以理解的是，在本发明实施例中，可在便携式生理参数检测装置的外部进行特殊设计，以告知用户当前生理参数检测的工作进度情况。例如，在将本发明实施例提供的生理参数检测装置集成在手环上时，可在该手环外部设置进度条窗口，进度条窗口的不同进度分别对应生理参数信息的检测、存储或传输等不同阶段，还可以显示当前电量，从而使用户能够自行判定是否需要继续使发电单元11产生电能，以维持检测模块20、存储模块30及传输模块40的正常工作。
在本发明实施例中，检测模块和存储模块正常工作时所需的电能由发电单元提供，而发电单元提供的电能来源于用户对发电单元的挤压或推压，与电池等储能器件的有限储能相比，在本发明中用户可根据需要使发电单元持续产生电能，因此不需要频繁地对储能器件重新充能或更换储能器件，从而提高便携式生理参数检测装置的使用便利性。此外，由于本发明的发电单元采用摩擦发电的物理发电方式向检测模块和存储模块提供正常工作时所需的电能，与现有的便携式生理参数检测装置中的电池等储能器件的化学发电方式相比，本发明的发电单元中不含有重金属等污染物质，因此，本发明所提供的便携式生理参数检测装置在废弃时产生的污染较小。
如图6所示，本发明还提供了一种生理参数检测方法，采用上述任一项技术方案所述的便携式生理参数检测装置，便携式生理参数检测装置包括检测模块、存储模块和供电模块，生理参数检测方法包括：
步骤100、用户使供电模块的发电单元摩擦发电，为检测模块和存储模块 提供正常工作时的电能。具体地，用户对发电单元进行按压或推压，使得发电单元中的两个绝缘层相互摩擦而各自产生电性相反的静电荷，各绝缘层中产生的电性相反的静电荷分别移动到与该绝缘层相接触的电极层上，使得两电极层之间产生电势差，进而使连接在两电极层上的外电路内产生电流，通过该产生的电流为检测模块和存储模块提供正常工作时的电能。在上述发电过程中，用户的按压和推压可以是用户主观进行的动作(例如用户用手指对发电单元位置进行按压或推压)，也可以是用户在进行日常活动时无意识地产生的动作(例如在用户跑动时发电单元与人体、衣物等之间产生的按压、摩擦等)。
步骤200、利用检测模块对人体进行生理参数检测，并生成生理参数信息。在该步骤中，生理参数检测装置通过检测模块中的传感单元(传感单元可包括血压传感器、心跳传感器等)对人体进行检测，获得各项生理参数，将上述各项生理参数以及进行生理参数检测的时间等信息整合成生理参数信息。通常，通过传感单元获得的生理参数信息为模拟信号，而模拟信号具有信息量大、保真性高的特点，与数字信号相比在储存和传输过程中花费的时间较长。因此，在用户对生理参数的精确程度要求较高时，可使检测模块直接输出模拟信号表示的生理参数信息。而在用户对生理参数的精确程度要求较低时，可在检测模块中设置转换单元，通过转换单元将用模拟信号表示的生理参数信息转换为用数字信号表示的生理参数信息，减少其在储存和传输过程中耗费的时间，进而减少其在储存和传输过程中对电能的消耗。
步骤300、存储模块接收并存储生理参数信息。
在本发明实施例提供的生理参数检测方法中，通过用户对发电单元的挤压或推压，为检测模块和存储模块提供电能，与电池等储能器件供电器件的有限储能相比，在本发明实施例中用户可根据需要使发电单元持续产生电能，因此不需要频繁地对储能器件重新充能或更换储能器件，从而使得便携式生理参数检测装置的使用便利性得到提高。
此外，由于本发明实施例提供的生理参数检测方法采用摩擦发电的物理发电方式以向检测模块和存储模块提供正常工作时所需的电能，与使用电池等储能器件的化学发电方式相比，本发明实施例所提供的生理参数检测方法所采用的发电单元中不含有重金属等污染物质。因此，本发明实施例所提供的生理参数检测方法所采用的生理参数检测装置在废弃时产生的污染较小。
进一步地，在本发明实施例提供的生理参数检测方法中，仅在用户使便携式生理参数检测装置中的发电单元摩擦发电时使便携式生理参数检测装置启动并进行生理参数检测，而在平时使便携式生理参数检测装置处于待机或休眠等未工作状态，因此，与长时间不间断地维持运行的生理参数检测方法相比，本发明实施例提供的生理参数检测方法能够节省大量电能。
如图7所示，根据本发明的另一个示例，在步骤100后，所述方法还可以包括：
步骤400、传输模块将存储在存储模块中的生理参数信息传输至与便携式生理参数检测装置连接的终端。例如，传输模块在生理参数检测装置与终端之间建立通信连接(包括无线相容性认证连接wifi、红外线连接或超声信号连接等无线连接，或有线连接)，进而向终端上传存储在存储模块中的生理参数信息，由终端根据该生理参数信息，对人体健康状态进行进一步的分析、比较和预测。
如图8所示，根据本发明的一个示例，步骤400可以包括：
步骤410、传输模块判断除本次检测获得的生理参数信息以外，存储模块内是否存储有上次传输中未全部传输至终端的生理参数信息；
步骤420、当存储模块内存储有上次传输中未全部传输至终端的生理参数信息时，传输模块优先将上次传输中未全部传输至终端的生理参数信息传输至终端，然后将本次检测获得的生理参数信息传输至终端。
由于在传输模块将生理参数信息上传至终端的过程中，若用户中断对发电单元的按压或推压而造成便携式生理参数检测装置意外断电，将导致生理参数信息上传不完整甚至上传错误，因此，在本发明实施例提供的生理参数检测方法中，结合步骤410和步骤420，通过传输模块判断存储模块中是否存储有上次传输中未全部传输至终端的生理参数信息，并在判断结果为是时，继续向终端传输上次传输中未全部传输至终端的生理参数信息，从而确保便携式生理参数信息检测装置能够完整地将每次检测得到的生理参数信息上传至终端，使得终端能够更好地对用户的健康状态进行分析、比较和预测。
参见图9，根据本发明的另一个示例，生理参数检测方法还可以包括如下步骤。在步骤901中，对人体进行生理参数检测，并生成生理参数信息。其中，所述供电模块的发电单元摩擦发电，为所述便携式生理参数检测装置提供正常工作时的电能。也就是说，在便携式生理参数检测装置没有电的情况 下，供电模块的发电单元可以发电来为便携式生理参数检测装置提供电能。另外，根据本发明的另一个示例，在对人体进行生理参数检测之后，还可以将生理参数信息进行存储，以方便用户查看和分析。
在上述实施方式的描述中，具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
以上，仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应以权利要求的保护范围为准。
