摩擦电纳米发电机（TENG）的工作原理是摩擦和接触带电，这是在日常生活中观察到的常见现象。teng正在接近商业化，特别是在小规模能量收集和自供电传感方面。最近，随着数码玩具的推出，玩具和游戏行业吸引了大批观众。在本文中，我们嵌入了teng来为玩具供电并在其特定应用过程中进行操作。我们修改了两个潜在的电子演示应用，使用TENG用于龙虾玩具（LT-TENG）和压力球（SB-TENG）装置。在负载电阻值为10 MΩ时，LT-TENG器件的最大电响应为60v /2µa，功率为55µW，功率密度为0.065µW m−2。同样，由铝和PDMS作为摩擦电层制成的SB-TENG器件在负载电阻为10 MΩ时，瞬时功率为6 mW，功率密度为3.5 mW m - 2，最大电输出响应为800 V，峰值电流为4µa。此外，TENGs的层被聚乙烯填充，以保持纳米发电机在恶劣环境条件下的性能，特别是在潮湿环境下。阻水性研究证明，填料SB-TENG具有不透水的特性。LT-TENG设备配有四个led，在启动手柄时设备会亮起。SB与测量仪器连接，以记录SB被压的力的大小。采用的方法为将这些传统玩具转变为无电池电子设计及其商业化铺平了道路。
Triboelectric nanogenerators (TENG) work on the principle of tribo and contact electrification, which is a common phenomenon observed in daily life. TENGs are moving closer to commercialization, particularly for small scale energy harvesting and self-powered sensing. The toys and games industry has attracted a large audience recently with the introduction of digital toys. In this paper we embedded TENGs to power up a toy and operate during its specific application. We have modified two potential electronic demonstrator applications using TENG for lobster toy (LT-TENG) and stress ball (SB-TENG) device. The LT-TENG device generates a maximum electrical response of 60 V/2 µA, with a power of 55 µW and power density of 0.065 µW m−2 at a load resistance value of 10 MΩ. Similarly, the SB-TENG device made of aluminum and PDMS as the triboelectric layers generates a maximum electrical output response of 800 V and 4 µA peak to peak current with an instantaneous power of 6 mW and a power density of 3.5 mW m−2 respectively at a load resistance of 10 MΩ. In addition, the layers of the TENGs are packed with polyethylene to maintain the performance of the nanogenerator under harsh environmental conditions, especially with humid environments. The water resistance studies proved that the packed SB-TENG is impervious to water. The LT-TENG device is accompanied by four LEDs, and the device lights up upon actuating the handle. The SB is connected with the measuring instrument to record the quantity of force at which the SB is pressed. The adopted approach paves the way to convert these traditional toys into battery-free electronic designs and its commercialization.
