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 minimum bend 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.
