NTT Corporation (President and CEO: Akira Shimada, “NTT”) and the Graduate School of Frontier Sciences, The University of Tokyo (GSFS) have successfully produced the world's first communication signal using a battery and a circuit composed of environmentally friendly materials free of scarce elements and hazardous substances. As the Internet of Things (IoT) proliferates, all sorts of objects are being transformed into devices, expanding their range of services and applications. However, concerns exist about the environmental impact associated with the disposal of consumables converted into sensor devices. To address this issue, NTT is promoting the research and development of devices using materials that have a low environmental impact once discarded.

NTT和GSF正在通过消除稀缺材料和危险物质的使用来探索对环境友好型电池的改进。欧洲杯足球竞彩这两个组织共同制造了使用有机半导体技术由环保电路制成的新概念验证（POC）传感器设备，并成功地使用了这些类型的可持续材料来生成世界上第一个通信信号。欧洲杯足球竞彩该技术可用于在未密封检测中传感设备（例如，在一次性水瓶中），在药丸包装中传感设备，以确定患者是否忘记了服用处方药或减少观察性天气浮标的环境影响（图（图）1）。
在2018年，NTT通过制造和验证“重返地面电池”的电池操作（由肥料成分和有机材料组成），迈出了这一开发的第一步。欧洲杯足球竞彩然后，合作者采访了废物管理领域的专家，以确定应选择哪些材料以实现低环境影响。欧洲杯足球竞彩作为回应，两人消除了包含稀缺元素（不考虑资源可用性）和危险物质（表欧洲杯足球竞彩1和2）的材料。
Using these materials, researchers at NTT collaborated with Professor Junichi Takeya’s laboratory at GSFS to create an environmentally friendly circuit. Together, the researchers developed an organic transistor manufacturing process in which all electrodes are made of carbon material (carbon-electrode organic transistors) and are used to construct analog oscillation circuits and digital modulation circuits with CMOS. Researchers formed a three-dimensional conductive porous structure, applied carbon as an electrode and increased the voltage by serializing the batteries.
NTT plans to continue developing related technologies, collaborating with external organizations and companies to explore use cases unique to“low environmental impact,”and jointly implementing novel services. You can read more details about this research inScientific Reportshere从10月7日起th, 2022.
