HP实验室的研究人员最近开发出一种名为Memory Spot的存储芯片,不但具有无线读写功能,而且尺寸只有一颗米粒大小。这种芯片的原型产品包含256Kb～4Mb的存储颗粒,并能以10Mbps的速率无线传输数据,工作不需要自带电池。那么,工作电压和电流由何处获得?据HP介绍,这是得益于一种称之为感应耦合的技术,这种技术通过一个共享的电磁场,可以让电力从一个组件传输到另一个组件。Memory Spot芯片中的电能,就是从向其读或写数据的其他电子组件中感应耦合而获得的,芯片内置感应天线。这种芯片有何用处?HP认为凭借上述特性,可以让其来存储和传输视频 Researchers at HP Labs recently developed a memory chip called the Memory Spot, which features wireless read and write capabilities and is only one grain size. The prototype of this chip contains 256Kb ~ 4Mb of storage particles, and to 10Mbps wireless transmission of data rates, work does not need to bring their own batteries. So where do the operating voltages and currents come from? According to HP, this is due to a technique called inductive coupling that uses a shared electromagnetic field to transfer power from one component to another . Memory Spot chip in the electrical energy, is to read or write data from other electronic components in the inductive coupling of the chip built-in inductive antenna. What is the use of this chip? HP believes that with the above features, allowing them to store and transmit video
