## Custom-Made Stretchable Interconnects to Fit Your Specific Needs
#### We custom-make stretchable interconnects tailored to your unique size, trace routing, connector output, and component attachment requirements.
## Why Liquid Wire?
### Reliable Data & Power Transmission
#### Our interconnects Metal Gel™ traces ensures consistent data and power delivery with electrical conductivity at 2.1 x 10^6 S/m.
### Withstand Stretching, Bending and More
#### Our interconnects maintain their integrity and performance even when subjected to significant stretching. They can even be subjected to a hard crease and quickly recover to their original performance.
### Solving the "Hard-to-Soft" Challenge
#### Liquid Wire has patented a superior solution to this challenge that seamlessly connects hard components—such as microcontrollers, sensors, and chips—to soft, pliable materials through our stretchable circuitry.
## Flexing Our Performance
### Robust and Reliable Design
#### Our interconnects are typically encapsulated in thermoplastic polyurethane (TPU), combining stretchability with durability. They are built to withstand millions of strain cycles, ensuring long-lasting performance in dynamic environments.
#### With reliable performance **over 1 million cycles** **at a 1Hz cycle rate and 30% displacement**, our interconnects are ideal for applications that demand consistent reliability under stress.
### Stretchability and Flexibility
#### Designed to handle elongations significantly in excess of **100%**, depending upon the substrate, our interconnects maintain their integrity and performance even when subjected to significant stretching.
#### The minimumbend radius of **less than 1mm at the trace and 2.5mm** at the board interface enables maximum flexibility without risking mechanical failure. You can even pinch an interconnect with a hard crease, and it will recover quickly.
## Applications
### Board-to-Board Electrical Connection
#### Stretchable interconnects maintain reliable connectivity and performance even under significant deformation and movement, making them ideal for dynamic and compact environments.
### Flexible Flat Cable (FFC) Replacement
#### Offering a more flexible and durable alternative to traditional flat cables, primarily suitable for signal transmission.
### Dynamic Cabling for Communication Protocols
#### Suitable for SPI and Inter-Integrated Circuit (I2C) communications.
### Complete Packaging Solutions
#### Integrating stretchable electronics within TPU with integrated polyimide contact pads for connecting active components provides a robust and flexible system for many applications.
