Scientists use frictional power generation to transform traditional toys into intelligent electronic toys without batteries.
[Technews technology new newspaper] one day, the rubber ducks may be able to shine without battery, which comes from a component called frictional power generation nanoscale, converting traditional electronic toys into smart electronic toys that do not need battery power.
Triboelectric Nanogenerator (TENGs) is an element that uses the principle of friction lifting (Triboelectric Effect) to design a sensor or collect energy. Basically, any material can be used as a contact surface, such as clothing, paper, etc., and a team from the Soochow University in China also released an item in the previous period. They made use of the friction between rainwater and solar panels to generate electricity on rainy days.
According to the American Academy of Pediatrics, almost every child is exposed to electronic toys around 4 years of age. These toys attract children’s attention through light or simple beeps, but adults need to replace their batteries frequently for their toys behind their back.
But if we use the principle of frictional electricity generation, toys can also “self supply”, so long as we press one eye, we will shine. Sang-Jae Kim team, a material scientist at the Cheju National University, is developing an electronic toy for children without battery power, using TENGs to collect the energy (charge) generated by mechanical vibration, similar to the static electricity formed when the hair is rubbed with the balloon, and then convert it into a available form.
The researchers put an aluminum electrode made of TENGs sandwiched between the environmental silica gel film, combined with rubber ducks and clapping toys, and then squeezing or shaking the electrodes into the film to produce electric charges. TENGs can collect enough energy to supply the toy LED lamp, such as the eye area.
In the past, applying TENGs to toys and trying to commercialize is a big challenge, because energy storage and conversion efficiency is too low, but the South Korean team can make use of TENGs more effectively through new design, make traditional toys into intelligent power supply toys more bright, and have the opportunity to further apply to the medical sensor. Team papers were published in the Journal of Sustainable Chemistry & Engineering.
