Data theft from the desktop system using devices capable of storing data is a serious problem that causes great harm to an individual or a company. It is essential to excogitate a way to reduce the problem. The triboelectric nanogenerator (TENG), recently introduced as a light-weight, easy-to-design energy harvester, works on the coupling of electromagnetic induction and contact electrification. In this work, a TENG is used to incorporate a smart feature in the table which triggers an alarm if an intruder is using the desk. The TENG works in the single-electrode contact-separation mode and in the sliding mode. The Kapton backed by aluminum is used as active triboelectric layers while the material on apparels or hand skin acts as opposite triboelectric material. The device is systematically studied for its electrical performance using materials such as jeans, cotton, paper, etc. The device gives the highest output voltage and current of ~200 V and 2.2 μA in case of paper. Finally, a smart table is demonstrated using the as-fabricated TENG coupled with the Arduino board which triggers an alarm if a person is accessing the desk. This work can extend the application of the TENG for the development of smart furnitures.

使用能够存储数据的设备从台式机系统盗窃数据是一个严重的问题，会对个人或公司造成极大伤害。找出减少问题的方法至关重要。摩擦电纳米发电机（TENG）最近作为一种轻巧，易于设计的能量收集器而推出，致力于电磁感应和接触带电的耦合。在这项工作中，使用TENG将智能功能集成到桌子中，如果入侵者正在使用桌子，该功能会触发警报。TENG在单电极接触分离模式和滑动模式下工作。铝支持的Kapton用作活性摩擦电层，而服装或手部皮肤上的材料则用作相反的摩擦电材料。使用牛仔裤，棉布，纸张等材料对该设备的电气性能进行了系统研究，该设备在使用纸的情况下提供最高的输出电压和电流，约为200 V和2.2μA。最后，使用预制的TENG和Arduino板演示了智能表，如果有人在访问办公桌，该板会触发警报。这项工作可以扩展TENG在智能家具开发中的应用。
