Solar cell layer on wearable displays


When it comes to technology, given the same package, we always want more fitted in. Such that in our smartwatches today, we're looking at features from the basic heartrate monitor to dedicated standalone GPS and even an ECG function we're starting to see more. And when you do use the functions, you consume more power from the device's battery. This translates to more recharging of the device and downtime.

Adding a solar cell layer on top of the screen of your device is going to help increase the intervals between the usage and charging of the device.
