With the development of smartphones, portable digital cameras have been gradually forgotten, but they still have their own advantages, that is, powerful flash, but this advantage may soon be replaced by smartphones. Lee Pooi See, an associate professor at Nanyang Technological University in Singapore, has developed a thin and powerful capacitor that can reach the level of ordinary digital cameras when combined with a xenon flash.
The silver part in the picture above is the capacitor commonly used in xenon flash lights in smartphones. The one below is a new ultra-thin capacitor developed by Lee Pooi See.
This new type of capacitor stacks copolymers together with a thickness of only 1mm, but its speed is several times that of ceramic-based capacitors. With the same volume, it can provide power for more powerful xenon flash lamps, so that smartphones do not have to worry about insufficient light when taking photos at night.
