可生物降解的瞬态电子设备，在其寿命结束时很容易分解为安全的组成部分，是解决电子废物的一个重要新兴研究方向，也是实现新应用的一个重要方向，例如可穿戴健康监测器，它可以在使用结束时很容易地从身体上洗掉。普鲁兰多糖是一种广泛使用的可食用基质，其自然生物降解，并且先前已与银轨道一起用于产生瞬态电子器件。然而，银轨道通常不是可生物降解的。本文演示了可生物降解的瞬态设备的锌轨道的创建，其中锌约为每日推荐摄入锌量的一半。我们展示了在1-10 $\Omega/\square$的范围内的极化率，用于电极和天线应用中的潜在用途。
Biodegradable transient electronics, devices which easily breakdown to safe constituent parts at their end of life, are an important emerging research direction for tackling electronic waste, as well as enabling new applications such as wearable health monitors which can easily be washed off the body at the end of use. Pullulan is a widely used edible substrate which naturally biodegrades and has previously been used with Silver tracks for creating transient electronics. However, Silver tracks are not generally biodegradable. This paper demonstrates the creation of Zinc tracks for biodegradable transient devices, where the Zinc is approximately half of the recommended daily allowance to Zinc to be ingested. We demonstrate resistivities in the range 1–10 $\Omega/\square$ for potential use in electrode and antenna applications.
