Soon, wearable devices that can be charged with body heat - electrical energy storage systems

In addition to the traditional capacitor charging method, this innovative super capacitor allows the use of thermal energy to complete the charging.
You will soon be able to use your body heat to power your wearable device thanks to a new flexible super capacitor that can take advantage of the heat from the surrounding environment to charge itself
No external power supply or battery replacement is required.
Researchers have developed a new concept of energy storage.
Hot charging solid-
National Super capacitor.
In addition to the traditional capacitor charging method, this innovative super capacitor allows the use of thermal energy to complete the charging.
"This is the first time that it has discovered a solid state.
State polymer electrolyte can produce A large thermal induction voltage, "said Choongho Yu, A professor at the University of Texas A & M.
"Then, the voltage can be used to trigger an electrochemical reaction in the electrodes used for charging," Yu said . ".
Hot charging solid-
The state super capacitor works by converting thermal energy into electrical energy and then storing it in the device at the same time.
For example, human body heat or any heat dissipation object that creates a temperature difference with the surrounding environment can be used to charge the capacitor without an external power supply.
The super capacitor is also flexible because it can be used as a power supply for wearable electronics and can be integrated into a wireless data transmission system to operate the Internet of Things (IoT)sensors.
The Internet of Things is the concept of connecting various electronic devices and sensors for data communication and exchange, which is especially useful in real life. Time monitoring.
Yu and his PhD student, Suk Lae Kim, took advantage of a physical phenomenon called the Soret effect --using a solid-
State polymer electrolyte where the ions are moved from the thermal side to the cold side along the temperature gradient of the super capacitor-
High heat induced voltage is generated.
"This hot self
Rechargeable flexible super capacitors powered by thermal diffusion ions have great potential in providing power to electronic devices in a completely new way --
There is no conventional external power supply or battery replacement, "Yu said.
The study is published in the journal Advanced Energy Materials.
