柔性可生物降解电子产品有可能成为临时电子活性医疗植入物的核心部件。与传统的慢性植入物相比，可生物降解电子产品可能会显示出许多优势。生物可降解电子产品的两个重要的长期目标是(1)提供足够的电力和(2)减少设备部署的侵入性。可食用电子设备能够应对这两个挑战。在这里，我们介绍与非侵入性部署策略兼容的电化学电子电源，这些电源完全由可食用材料和普通饮食中消耗的天然前体组成。本文开发的电流源由机载钠离子电化学电池供电。通常可以产生高达0.6V的电压和5-20微安的电流。这些设备可以作为可食用电子设备的使能平台技术，用于人体内组织的非侵入性传感和刺激。
Flexible biodegradable electronics have the potential to serve as the centerpiece for temporary electronically active medical implants. Biodegradable electronics may exhibit many advantages over traditional chronic implants. Two important long-term goals for biodegradable electronics are (1) supplying sufficient power and (2) reducing the invasiveness of device deployment. Edible electronic devices are capable of addressing both challenges. Here, we introduce electrochemical electronic power sources that are compatible with non-invasive deployment strategies and are composed entirely of edible materials and naturally occurring precursors that are consumed in common diets. The current sources developed herein are powered by onboard sodium ion electrochemical cells. Potentials up to 0.6 V and currents in the range of 5-20 mu A can be generated routinely. These devices could serve as an enabling platform technology for edible electronics used in non-invasive sensing and stimulation of tissues within the human body.
