现有无线遥控式开关可以解决布线问题，但通常都需要采用干电池或可充电蓄电池来供电，当代社会越来越重视绿色环保，废弃的旧电池将会成为环境污染的重大问题。

图4为能量收集器示意图。
下面结合实施例和附图对本发明做进一步说明，本领域技术人员应该理解，实施例和附图只是为了更好地理解本发明，并不用来做出任何限制。
参见图1和图2，根据本发明的无线开关装置主要包括开关盒1和开关本体2，开关盒1和开关本体2相互独立。开关盒1包括摩擦件、电能收集/转换单元15和信号发射单元16，其中摩擦件响应于摩擦动作而产生相应的电能；电能收集/转换单元15将摩擦件产生的电能转换成符合要求的电能；信号发射单元16接收上述电能并发射相应的开关信号。开关本体2独立于开关盒1并用于控制相应电器的电路开闭，开关本体2具有主回路开关控制单元，主回路开关控制单元响应于信号发射单元16所产生的开关信号而开闭相应电器的电路。
开关盒1的样式和设置位置可以根据具体应用进行选择，待最终固定于所需位置即可。在本发明的一个具体实施例中，开关盒1构造成壁式开关盒形式，并最终固定于室内墙壁期望位置。在本发明的另一个具体实施例中，开关盒1构造成可移动式开关盒，并能够选择性固定于室内摆放物上的期望位置。当构造成可移动式开关盒时，其固定面上设置有可重复固定装置，可重复固定装置例如可以为可重复粘贴胶皮或磁铁，从而可以方便地固定于所需位置。
开关本体2通常安装在待控制电器附近，例如当待控制电器为电灯时，开关本体2安装在电灯的灯罩内，从而使开关本体2与电灯成为一体，减少开关本体2与电灯之间的接线。开光本体2既可以在生产电灯时与电灯安装在一起，也可以在对现有有线开关控制的电灯进行无线控制改造时进行安装。
参见图1，在本发明的一个具体实施例中，摩擦件包括绝缘背衬
11、导电层12、摩擦体13以及摩擦滑动件14，其中导电层12附着在绝缘背衬11上，摩擦体13固定在导电层12上。导电层12可以由金箔或氧化锡制成。摩擦体13则可以设置成图示的硅橡胶柱(或棒)阵列。摩擦滑动件14可以由类似皮肤材料例如硅橡胶板等橡胶类材料制成，能够相对于摩擦体13产生摩擦滑动，从而产生电荷，产生的电荷通过导电层12传递到电能收集/转换单元15。在本发明的优选实施例中，可以省略摩擦滑动件14，直接通过人的手指与摩擦体13进行摩擦来产生电荷，从而使本发明的无线开关装置部件更加简化。在另外的实施例中，也可以省略电能收集/转换单元15或将电能收集/转换单元15的功能直接集成于信号发射单元16。
参见图2，在本发明的一个具体实施例中，开关本体2的主回路开关控制单元包括主回路开关控制器21和主回路开关22。其中主回路开关控制器21主要包括依次连接的开关信号接收器、解码器以及主回路开关控制驱动器；主回路开关22可以是可控硅式功率三极管、功率场效应管或继电器，其通断由主回路开关控制驱动器控制。信号发射单元16发射的信号通常为无线脉冲信号，例如可以是无线电磁信号、红外信号或超声波信号等。为了使同一开关仅能控制与之对应的电器，实现定向控制，信号发射单元16发射的信号可以为加密信号。主回路开关控制器21通过开关信号接收器接收信号发射单元16发射的信号，通过解码器对加密信号进行解码，如果信号正确，则通过主回路开关控制驱动器来驱动主回路开关22的开启或关闭；如果信号不正确，则停止下一步反应。
参见图3，电能收集/转换单元15包括能量收集器151和控制器152。工作时，摩擦电能被能量收集器151收集，并将摩擦件产生的电能转换成符合要求的电压和电流，能量收集器151为控制器152和信号发射单元16提供电源。控制器152控制信号发射单元16发射相应的开关信号。
参见图4，能量收集器151用于收集小的摩擦能源并生成系统电源，而不使用传统的可充电电池电源。其可直接连接至导电层12，对电压波形进行校正并将收集的能量存储在一个外部电容器上，通过一个内部并联稳压器泄放任何多余的功率并借助一个毫微功率高效
降压型稳压器来保持一个已调输出电压。内部全波桥式整流器可通过两个差分输入来使用，即负责对输入进行整流的PZ1和PZ2。该整流输出随后被存储在位于VIN引脚上的一个电容器上，并可用作降压型转换器的能量储存器。低损耗桥式整流器具有一个约400mV的总压降和典型压电生成电流(一般在10μA左右)。该电桥能够传输高达50mA的电流。当VIN引脚上拥有足够的电压时，降压型转换器将被使能以产生一个稳压输出。
降压型稳压器采用了迟滞电压算法，以通过来自VOUT检测引脚的内部反馈对输出加以控制。降压型转换器通过一个电感器将一个输出电容器充电至一个略高于调节点的数值。它通过利用一个内部PMOS开关使电感器电流斜坡上升至260mA、并随后利用一个内部NMOS开关使电感器电流斜坡下降至零以完成该任务，从而有效地将能量输送至输出电容器。其提供稳压输出的迟滞方法降低了因FET开关操作所引起的损耗，并在轻负载条件下保持了一个输出。
下面介绍本发明的无线开关装置应用于室内装修的具体实例，其中无线开关装置主要包括开关盒1和开关本体2。其中开关盒1具有摩擦件，响应于摩擦动作而产生相应的电信号。其中开关本体2与开关盒1物理隔开，开关本体2具有控制单元，控制单元响应于摩擦件所产生的电信号而控制相应电灯的电源电路开闭。特别当对房间内原有有线控制的电灯进行改造时，可以方便地将开关本体2安装到原有电灯的灯罩内，开关盒1在室内装修期间位置可改变，并在装修结束后能够根据住户需要固定于室内所需位置。实现由有线控制到无线遥控的升级改造。既能随意改变开关的位置又无需凿墙布线，后期使用时又安全又省电。
另外，尽管也可以考虑采用在开关盒中设置致动部件，并通过人工致动该致动部件而将相应的机械运动直接转换成电能以产生相应的遥控信号，但由于这种机械运动所转化的能量是相对有限的，通常不能满足实际使用要求；而且这种情况下还需要设计复杂的机械构造，这会使得开关非常复杂，安装和使用不便，并且还会引起过高的成本。
本发明的无线开关装置通过使用高能量转换率摩擦材料而借助例如手指的摩擦运动来产生控制电信号，从而结构简单、体积小巧、使用方便并且成本大大降低。
