This product is an ultra-thin polyether-based TPU film specifically designed for flexible electronic skin (E-skin). Developed and manufactured in-house by our factory in Dongguan, it serves as the core substrate material for wearable medical sensors and robotic bionic tactile skin.
Performance Parameters: Thickness 12–50 μm; adjustable hardness 75A–95A; elongation at break 500–800%; resists permanent deformation even after tens of thousands of repeated stretching and twisting cycles; withstands temperatures ranging from –40°C to 90°C; tear-resistant and abrasion-resistant.
| Use Cases | Recommended Thickness | Key Requirements |
| Robotic Gloves | 0.05mm-0.3mm(depending on the application) | Lightweight, adhesive-backed, skin-friendly, printable conductive silver paste Resists deformation and wrinkling during high-temperature bakingLong-term temperature resistance of 100°C+,excellent tear resistance Withstands baking at 140°C for 2 hours without deformation |
| Robot Joints | 0.03mm -0.1mm | |
| Flexible Sensors for Robots | 0.05mm -0.1mm | |
| General-Purpose Flexible Sensors | 0.05mm -0.1mm |
Processing Characteristics: Supplied in roll form; the surface is compatible with conductive inks, silver nanowires, carbon nanotubes, and magnetron sputtered metal coatings. Ultra-thin films can be paired with a release carrier film to prevent wrinkling during processing. Made of thermoplastic material, it supports hot pressing, thermal lamination, and ultrasonic sealing, making it suitable for industrial-scale mass production—unlike the small-batch laboratory processes typically associated with PDMS silicone.
Two Main Product Versions
Wearable Medical Version: 15–30 μm medical-grade polyether TPU, resistant to sweat hydrolysis, capable of microporous moisture permeability, skin-friendly and breathable, used for ECG and EMG patches, physiological sensor patches, and smart wound dressings. Polyester TPU must not come into contact with the skin.
Robotic Bionic Skin Version: High-fatigue-resistant, dense polyether TPU, emphasizing resistance to friction and repeated deformation, used for tactile skin on humanoid robots and sensing substrates for soft robots.
Our factory supports prototyping and custom specifications, supplying products to companies engaged in the R&D and mass production of flexible sensors and wearable devices.
