Flexible electronic products, especially those that are not easy to detect, can be conceived as minimizing objects that can be seamlessly integrated or unobtrusively and unblocked to paste onto other physical objects.
However, some technical problems hinder the effective integration of flexibility and the internet of things, among which energy autonomy is particularly important.
We define autonomous energy/power sources as energy sources that draw energy from objects connected to the device itself or the device, I . E. e.
Instead of external energy sources such as power outlets or the sun.
As more and more sensors are placed in remote, inaccessible places, or on autonomous/mobile systems, such as the human body, sensor nodes that operate without an external energy supply become critical.
Unfortunately, most of the power systems currently used for flexible electronic devices involve rigid batteries, which poses a number of obvious problems such as frequent charging and replacement of batteries and wearability.
In order for flexible electronic devices to truly operate autonomously, we need to combine flexible electronic devices with flexible power supplies to create an integrated energy source-
Autonomous and flexible electronic systems.
Examples of full development of flexible electronics or flexible power sources have been presented, but so far the lack of flexible power technologies has hindered the successful integration of both technologies.
Flexible batteries and super capacitors require frequent external charging and/or replacement and are therefore not autonomous. Radiation-
Supply sources such as solar cells or wireless antennas require constant external energy that the sun or RF cannot provide.
The flexible thermal power supply requires a higher temperature difference to generate sufficient power, while the friction or piezoelectric power supply requires the connected object to be in a constant state of high motion.
There are a few full examples, though. flexible, self-

These devices involve the transformation of an energy form (i. e. , mechanical)
To power small electronic devices, turn them into electric energy.
An embodiment involves coupling a flexible friction power supply or piezoelectric power supply with a light emitting diode on a flexible substrate;
What\'s more interesting is that the nano-structure integrates an array of semiconductor heterogeneous structures containing piezoelectric and optical emission elements on flexible substrates.
Applications for touch screens or motion sensors have been proposed, but due to the need for close contact and the need for additional electronic equipment to interpret the optical output in order to connect with other systems, the practicality is limited.
Another interesting demonstration is the flexible piezoelectric ceramic device used directly as a pacemaker.
However, the external mechanical force is required to stimulate the pulse, while the cost of piezoelectric ceramics is high and the transfer is super

The LED is powered by electric energy charging/discharging in the capacitor using the charging pump circuit.
In addition to energy autonomy, another important goal achieved using the device is operational autonomy, that is, the device does not need to be connected to other electronic devices to interpret its data output.
