Description

一种收集生物体运动能量的能源供给装置 技术领域
本公开涉及发电机技术领域，尤其涉及一种收集生物体运动能量的能源供给装置。
背景技术
植入式医疗电子器件，如心脏起搏器、脑起搏器等，在当今临床医学领域中占据了重要的地位，极大地改善了患者的症状和生活质量，具有显著的社会价值和经济价值。但作为新兴的医疗器械发展方向，植入式医疗电子器件的发展仍然面临许多问题亟待解决，尤其是长效能源供给问题。
现阶段植入式医疗电子器件主要依靠电池供电，工作寿命有限，一旦电池耗尽，病人不得不再次面对巨大的手术风险和经济负担。此外，还有些植入式医疗电子器件可利用无线充电技术进行充电，但患者需定期去往指定地点并借助专业设备，耗时耗力，增加了患者的负担。另外，植入式医疗电子器件也可采用收集生物运动能量转化为电能的能源供给装置作为长效能源供给，但现有技术的收集生物运动能量转化为电能的能源供给装置主要为压电式，此种装置由于需要采用压电材料，成本较高；另外受限于压电材料的面积大小，能量的输出功率也较低。
发明内容

相应地，本公开实施例还提供了一种植入式医疗电子器件，所述植入式医疗电子器件包括上述的收集生物体运动能量的能源供给装置。
本公开有益效果如下：
本公开实施例提供了一种收集生物体运动能量的能源供给装置及包括该收集生物体运动能量的能源供给装置的植入式医疗电子器件，该收集生物体运动能量的能源供给装置包括能量采集单元、整流单元以及储能单元；其中，能量采集单元用于在生物体运动时，通过感应该生物体与参考地之间的电位差产生感应电流；整流单元用于将能量采集单元输出的感应电流整流成直流电流，并为储能单元和/或负载提供电能；储能单元，用于在整流单元有电能输出时存储整流单元输出的电能，以及在整流单元无电能输出时为负载提供电能。也就是说，可利用摩擦起电和静电感应原理将生物体的动能转化为电能并进行整流、存储，以为负载提供长效能源供给，从而不仅可减轻患者的手术风险和经济负担；而且，由于能量的来源为整个生物体与参考地之间的电位差，因此可产生较大的感应电流，输出功率较高。
附图说明
为了更清楚地说明本公开实施例中的技术方案，下面将对实施例描述中所需要使用的附图作简要介绍，显而易见地，下面描述中的附图仅仅是本公开的一些实施例，对于本领域的普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其它的附图。

具体实施方式
为了使本公开的目的、技术方案和优点更加清楚，下面将结合附图对本公开作进一步地详细描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本公开保护的范围。
实施例：
本公开实施例提供了一种收集生物体运动能量的能源供给装置，该装置可应用于植入式医疗电子器件的长效能源供给。具体地，如图1所示，其为本公开实施例中所述收集生物体运动能量的能源供给装置的结构示意图，包括能量采集单元101、整流单元102以及储能单元103，其中：

所述储能单元103，用于在所述整流单元102有电能输出时存储所述整流单元102输出的电能，以及在所述整流单元102无电能输出时为所述负载提供电能。
也就是说，可利用摩擦起电和静电感应原理将生物体的动能转化为电能并进行整流、存储，以为负载提供长效能源供给，从而不仅可减轻患者的手术风险和经济负担；而且，由于能量的来源为整个生物体与参考地之间的电位差，因此可产生较大的感应电流，输出功率较高。
需要说明的是，人或其它动物等生物体与周围环境在摩擦时得失电子的能力存在差异，因此，生物体在运动时与参考地之间会形成相对的得失电子；又由于生物体是良导体，因此，在生物体任何部位上贴上能量采集单元，例如电极，即可形成发电机，在电极与负载之间形成电流回路。
可选地，所述负载可为植入式电子器件的设定的功能单元，其中，所述植入式电子器件包括一个或多个功能单元以及金属外壳。
也就是说，所述收集生物体运动能量的能源供给装置可为植入式电子器件的设定的功能单元供电，例如，可为心脏起搏器的脉冲产生电路中的555芯片供电，以使得脉冲产生电路产生设定频率的脉冲信号。
进一步可选地，所述能量采集单元101具体可为所述植入式电子器件的金属外壳。例如，如图2所述，其为所述收集生物体运动能量的能源供给装置的一种具体的结构示意图，可将植入式电子器件的金属外壳作为收集生物体运动能量的能源供给装置的能量采集单元，也就是说，可将收集生物体运动能量的能源供给装置设置于植入式电子器件的内部，并将植入式电子器件的金属外壳作为收集生物体运动能量的能源供给装置的电极，不仅保证了收集生物体运动能量的能源供给装置的结构完整性，将收集生物体运动能量的能源供给装置与生物体的体液隔离，确保了装置功能的稳定性；而且还有效利用了空间，不必扩大植入式电子器件的体积。
可选地，所述植入式电子器件的金属外壳可采用生物相容性较好的导电材料，如不锈钢、钴铬钼合金等；优选地，可采用钛合金材料，本实施例在此不再赘述。
例如，植入式电子器件可为心脏起搏器，心脏起搏器通常植入人体锁骨下的胸大肌筋膜之上，心脏起搏器的金属外壳可作为收集生物体运 动能量的能源供给装置的电极，在人体运动时，通过感应人体与参考地之间的电位差产生感应电流；整流单元可将心脏起搏器的金属外壳输出的感应电流整流成直流电流，并为储能单元和/或心脏起搏器的脉冲产生电路中的555芯片提供电能；储能单元可在整流单元有电能输出时存储整流单元输出的电能，在整流单元无电能输出时为555芯片提供电能。
可选地，所述整流单元102可包括整流桥301、电容302以及变压器303，如图3所示，其中：
所述整流桥301，用于将所述能量采集单元101输出的交流脉冲信号转换为直流脉冲信号；
所述电容302，用于对所述整流桥301输出的直流脉冲信号进行平滑滤波，得到幅值稳定的直流电流；
所述变压器303，用于将所述电容302两端的电压转换为所述负载的额定电压，或将经所述电容302滤波得到的幅值稳定的直流电流转换为所述负载的额定电流。
可选地，所述收集生物体运动能量的能源供给装置还可包括开关单元(图1中未示出)，用于：控制所述整流单元102输出电能或停止输出电能。
进一步可选地，所述收集生物体运动能量的能源供给装置还可包括控制单元(图1中未示出)，用于：
确定所述电容存储的电能小于设定的能量阈值(可根据实际需求灵活设置)时，控制所述开关单元断开；
确定所述电容存储的电能不小于设定的能量阈值时，控制所述开关单元闭合。
例如，如图4所示，其为所述收集生物体运动能量的能源供给装置的一种具体的结构示意图，开关单元可包括开关1和/或开关2，控制单元用于控制开关1和/或开关2的断开与闭合；以开关单元包括开关1和开关2为例，当控制单元确定电容存储的电能小于设定的能量阈值时，则控制开关1和开关2断开，由储能单元放电为负载提供额定的电能；当控制单元确定电容存储的电能不小于设定的能量阈值时，则控制开关 1和开关2闭合，由变压器的副线圈为负载提供额定的电能，并且储能单元进行充电。
需要说明的是，开关1以及开关2可为各自独立的单刀单掷开关，开关1和开关2也可采用一个双刀双掷开关，本实施例在此不作任何限定。
进一步可选地，所述电容可为电解电容、独石电容、陶瓷电容等，优选地，由于所述收集生物体运动能量的能源供给装置收集的能量为μW量级，能量较小，因此，所述电容可为漏电流较小的钽电解电容，以尽量避免流失过多的电能。
由此可见，本公开实施例提供的收集生物体运动能量的能源供给装置，无需昂贵的材料和复杂的制备技术，制作成本较低，具有较好的普及前景。
基于同样的发明构思，本公开实施例还提供了一种植入式医疗电子器件，所述植入式医疗电子器件包括本实施例所提供的上述收集生物体运动能量的能源供给装置。所述植入式医疗电子器件可为心脏起搏器、脑起搏器等医疗器械，本实施例在此不作任何限定。
综上所述，本公开实施例提供的收集生物体运动能量的能源供给装置及包括该收集生物体运动能量的能源供给装置的植入式医疗电子器件，包括能量采集单元、整流单元以及储能单元；其中，能量采集单元用于在生物体运动时，通过感应该生物体与参考地之间的电位差产生感应电流；整流单元用于将能量采集单元输出的感应电流整流成直流电流，并为储能单元和/或负载提供电能；储能单元，用于在整流单元有电能输出时存储整流单元输出的电能，以及在整流单元无电能输出时为负载提供电能。也就是说，可利用摩擦起电和静电感应原理将生物体的动能转化为电能并进行整流、存储，以为负载提供长效能源供给，从而不仅可减轻患者的手术风险和经济负担；而且，由于能量的来源为整个生物体与参考地之间的电位差，因此可产生较大的感应电流，输出功率较高。
另外，可将收集生物体运动能量的能源供给装置设置于植入式电子器件的内部，并将植入式电子器件的金属外壳作为收集生物体运动能量 的能源供给装置的电极，不仅保证了收集生物体运动能量的能源供给装置的结构完整性，将收集生物体运动能量的能源供给装置与生物体的体液隔离，确保了装置功能的稳定性；而且还有效利用了空间，不必扩大植入式电子器件的体积。此外，由于无需昂贵的材料和复杂的制备技术，制作成本较低，因此，具有较好的普及前景。
需要说明的是，附图和说明书中的任何元素数量均用于示例而非限制，以及任何命名都仅用于区分，而不具有任何限制含义。
尽管已描述了本公开的优选实施例，但本领域内的技术人员一旦得知了基本创造性概念，则可对这些实施例作出另外的变更和修改。所以，所附权利要求意欲解释为包括优选实施例以及落入本公开范围的所有变更和修改。
显然，本领域的技术人员可以对本公开进行各种改动和变型而不脱离本公开的精神和范围。这样，倘若本公开的这些修改和变型属于本公开权利要求及其等同技术的范围之内，则本公开也意图包含这些改动和变型在内。
