不断增长的数据处理需求需要不同的电子范例。电子学中的诸如低功率和高速度的优异性能能力可以通过包括使用功能材料的若干因素来获得，功能材料有时获得上级电子特性。基于换能的晶体管开关机构是这样一种可能性，其利用了作为机械引起的变形的函数的换能器的电特性的变化。该技术最初是为变形传感器开发的，现在正成为电子工业的中心舞台，作为新晶体管概念的基础，以规避晶体管小型化中的栅极电压瓶颈。在Nanotechnology的第37期中，Chang等人展示了压电晶体管（PET），其使用快速、低功率的机械转换机制将输入栅极电压信号传播到输出电阻调制中。Chang等人的研究结果将推动对压电缩放的进一步研究，以及未来推进此类设备所需的PET制造技术。
The ever increasing demand for data processing requires different paradigms for electronics. Excellent performance capabilities such as low power and high speed in electronics can be attained through several factors including using functional materials, which sometimes acquire superior electronic properties. The transduction-based transistor switching mechanism is one such possibility, which exploits the change in electrical properties of the transducer as a function of a mechanically induced deformation. Originally developed for deformation sensors, the technique is now moving to the centre stage of the electronic industry as the basis for new transistor concepts to circumvent the gate voltage bottleneck in transistor miniaturization. In issue 37 of Nanotechnology, Chang et al show the piezoelectronic transistor (PET), which uses a fast, low-power mechanical transduction mechanism to propagate an input gate voltage signal into an output resistance modulation. The findings by Chang et al will spur further research into piezoelectric scaling, and the PET fabrication techniques needed to advance this type of device in the future.
