Wearable devices are made to make our life more convenient and more suitable including functions like tracking people's health, virtual reality, sleep monitoring, GPS, and more. They are more and more common thanks to the development of the tech. Wearable electronic products have various requirements for the shape of the battery while the users unanimously require longer battery life. Up to now, it is believed that a lithium polymer battery (lipo) is the best choice for powering electronic wearable devices. Also, the tech of the battery is getting more advanced to achieve Higher-energy density and Wider working temperature. In this passage, we will look at some applications equipped with the curved lipo battery and a tool that especially helps you design the special-shape battery. Hope you custom your right battery successfully with the tool.

Applications using the curved battery:

The ones like Bluetooth headsets and AR/VR/MR headsets ramp up the fun for the consumers.
