When people talk about batteries used in electronic devices, or power units, they generally think of block structures
that occupy a large space inside the equipment.
This may be true for mobile phones and notebooks, but when it comes to ultra-thin wearable sensors and similar products, the situation is different
.
Researchers at the University of Illinois are working on a new type of power supply that is said to be thin and flexible
.
The large lithium-ion battery is cut into small pieces and then connected by a retractable circuit
.
Combining a very small battery with a retractable circuit gives the power scheme this thin, bendable, and scalable property
.
The researchers used millimeter-scale solid-state lithium-ion batteries to create this flexible battery
.
As mentioned above, tiny lithium-ion batteries are connected to solar cells using retractable circuits and placed on a
single-layer flexible substrate.
In the device, fold it up and the solar cell can be placed on top of the battery
.
The researchers demonstrated the technology, which combines a battery and a solar cell into a device that tracks and records the user's temperature
through thermal sensors and NFC.
This thin device can stretch up to 30% by itself and does not affect solar functions; At the same time, it also passed the test
in scenarios such as people riding and bathing.
Due to the ultra-thin nature of the sensor, the wearer often forgets its presence
.
This sensor has the potential to be used in the medical field in the future, where it can be used to wirelessly transmit patient data in hospitals, allowing medical personnel to put their experience out of keeping an eye on vital signs monitoring devices
