href="http://opticaltest.oecr.com" target="_blank" class="relatedlink">测量</a>。一种是使用者坐在椅子上，手指放在小型脉搏仪上测量脉搏，脉搏数据自动传输给PC，并<a href="http://display.oecr.com" target="_blank" class="relatedlink">显示</a>在显示器上。工作原理是，在椅子及脉搏仪中内置了电场通信模块，数据通过人体从脉搏仪传输给椅子。然后，这些数据再传输给以有线方式与椅子连接的PC。 另一种设定场景是，在计步器及身体组成测量仪中嵌入电场通信模块。这是一个当戴着计步器的使用者站到身体成分测量仪上时，测定数据可在两种设备间共享的系统。数据也是通过人体进行交换的。 <br><br>人体通信的研究很早以前就很盛行，有望获得的用途涵盖了从个人认证到<a href="http://electronic.oecr.com" target="_blank" class="relatedlink">电子</a>月票、可穿戴式设备间的数据传输、娱乐等多种领域。但是，以往仅有在个人认证系统中实验性导入的事例等，几乎没有电子<a href="http://b.oecr.com/sell" target="_blank" class="relatedlink">产品</a>厂商投产消费类产品用模块的先例。 <br><br>这些应用具有可在使用者无意识的情况下测量身体数据的长处。如果在椅子及床等日用品中预先内置人体通信模块，通过坐在椅子上、睡在床上等日常极为普通的行为，就能在不知不觉间测量脉搏及心电图等。这一特点对应用于老年人居家健康管理再合适不过了。 <br><br>由于电子元件厂商着手投产消费类产品用模块，在健康设备等方面采用人体通信技术看来指日可待。若从其应用范围的宽广度来考虑，这种健康产品甚至有可能成为一种用于消费类产品的无线通信主机。</td></tr></table> <!--[diy=diycontentbottom]--><div id="diycontentbottom"
