可打印功能材料的重要概念即将引起范式转变，我们将能够在室温下通过空气中的打印方法制造电子设备。印刷电子的一个有前途的应用是一次性电子贴片传感系统，它可以无任何限制地监测健康状况。运算放大器（OPA）是这种传感系统的重要组成部分，因为OPA能够进行各种各样的信号处理。在这里，我们展示了基于互补有机半导体技术的印刷OPA。它们可以在5 V标准安全电源下工作，最低功耗为150 nW，可用作放大器、各种数学运算器、信号转换器和振荡器。印刷的微功率有机OPA具有低电压操作和高通用性，将在不久的将来开辟一次性电子贴片传感系统。
The important concept of printable functional materials is about to cause a paradigm shift that we will be able to fabricate electronic devices by printing methods in air at room temperature. One of the promising applications of the printed electronics is a disposable electronic patch sensing system which can monitor the health conditions without any restraint. Operational amplifiers (OPAs) are an essential component for such sensing system, since an OPA enables a wide variety of signal processing. Here we demonstrate printed OPAs based on complementary organic semiconductor technology. They can be operated with a standard safe power source of 5 V with a minimal power consumption of 150 nW, and used as amplifiers, a variety of mathematical operators, signal converters, and oscillators. The printed micropower organic OPAs with the low voltage operation and the high versatility will open up the disposable electronic patch sensing system in near future.
