我们提出了一种类型的电子产品，可以在可控的时间尺度内的水分的存在下溶解。物理瞬态电子学是一种可以以可控方式物理消失的电子形式，对于新兴应用来说非常有前途。目前报道的大多数瞬态过程仅发生在水溶液或生物流体中，对触发和降解过程的控制有限。我们报告新的水分触发的物理瞬态电子，免除再吸收解决方案的需要，可以完全消失在良好控制的时间范围内。触发的瞬态过程开始于在空气中存在痕量水分的情况下聚酸酐底物的水解，该过程可以产生腐蚀性有机酸的产物以消化各种无机电子材料和组件。聚酸酐是唯一一种表面腐蚀的聚合物，这是一个独特的特征，可以使功能设备在预定义的时间范围内稳定运行。这种新型触发瞬态模式的明显优点包括，可以通过改变湿度水平和改变聚合物基板的组成来精确控制器件的寿命。瞬变时间尺度可以从几天调整到几周。各种瞬态器件，从无源电子器件（如天线，电阻器和电容器）到有源电子器件（如晶体管，二极管，光电子器件和存储器），以及作为平台演示的集成系统已经开发出来，以说明概念和验证这种设计策略的可行性。
We present a type of electronics that can be dissolved upon the presence of moisture within a controllable time scale. Physically transient electronics, a form of electronics that can physically disappear in a controllable manner, is very promising for emerging applications. Most of the transient processes reported so far only occur in aqueous solutions or biofluids, offering limited control over the triggering and degradation processes. We report novel moisture-triggered physically transient electronics, which exempt the needs of resorption solutions and can completely disappear within well-controlled time frames. The triggered transient process starts with the hydrolysis of the polyanhydride substrate in the presence of trace amounts of moisture in the air, a process that can generate products of corrosive organic acids to digest various inorganic electronic materials and components. Polyanhydride is the only example of polymer that undergoes surface erosion, a distinct feature that enables stable operation of the functional devices over a predefined time frame. Clear advantages of this novel triggered transience mode include that the lifetime of the devices can be precisely controlled by varying the moisture levels and changing the composition of the polymer substrate. The transience time scale can be tuned from days to weeks. Various transient devices, ranging from passive electronics (such as antenna, resistor, and capacitor) to active electronics (such as transistor, diodes, optoelectronics, and memories), and an integrated system as a platform demonstration have been developed to illustrate the concept and verify the feasibility of this design strategy.
