Imagine a world where you can tell time with a simple tap on your skin. Thanks to a revolutionary new technology called stretchable electroluminescent (ACEL) displays, this futuristic vision may soon become a reality.
The Challenge of High Voltage
ACEL displays are thin, flexible panels that emit light when an electric current is applied. They hold immense promise for wearable applications, such as epidermal stopwatches and fitness trackers. However, a significant hurdle has prevented their widespread adoption: the high voltage required to operate them.
A Breakthrough in Voltage Reduction
Researchers at the University of California, Berkeley have made a groundbreaking discovery that could pave the way for safe and practical ACEL displays. They have successfully reduced the voltage required to operate ACEL displays to the 10-35V range, making them suitable for use on human skin.
Creating the Epidermal Stopwatch
To demonstrate the potential of their technology, the researchers constructed a 4-digit 7-segment display and applied it to the back of a hand. The display was connected to an iRobota Mega and driver circuitry to create a functional digital timepiece. The result was a fully functional epidermal stopwatch that could be worn comfortably on the skin.
The Future of Epidermal Displays
The development of epidermal ACEL displays represents a significant leap forward in the field of wearable technology. This new technology has the potential to revolutionize the way we interact with devices, making them more intuitive and seamlessly integrated with our bodies.
Bonus: Imagine a world where your clothes could display real-time information, where your skin could act as a control panel for your smart home, or where your health data could be displayed directly on your body. Epidermal ACEL displays could make all of this possible, opening up a new era of human-computer interaction.
The possibilities are endless, and the future of epidermal displays is incredibly exciting. As the technology continues to develop, we can expect to see even more innovative and groundbreaking applications in the years to come.
