Printed Stretchable Transistors

 

VALUE PROPOSITION
Stretchable electronic systems represent a cutting-edge technology that combines the flexibility of materials with the functionality of electronic components. These systems are designed to bend, stretch, and conform to various shapes without compromising their performance, making them ideal for a wide range of applications. By integrating electronic circuits into flexible substrates, such as polymers or elastomers, stretchable electronics enable the development of wearable health monitoring devices, soft robotics, electronic skin for prosthetics, and flexible sensors for industrial use. This technology holds potential to transform industries by providing enhanced sensory feedback, improved control, and adaptability to challenging environments, ultimately leading to innovative solutions and improved quality of life.

 

DESCRIPTION OF TECHNOLOGY

The present technology incorporates printed, intrinsically stretchable thin-film devices fabricated using techniques such as printing stretchable polydimethylsiloxane (PDMS) substrates with carbon nanotube (CNT) based thin-film transistors and integrated logic circuits. These devices can be formed on stretchable elastomer substrates as well, and involve methods for formulating printable stretchable dielectric layer inks using nanoparticles like barium titanate (BaTiO3) or other high dielectric constant materials, mixed with PDMS or elastomer oligomers in suitable solvents. The process includes magnetic stirring, sonication, O2 plasma treatment, deposition of CNT networks, patterning electrodes, defining channels, and encapsulation to create stretchable thin-film transistor elements.
