Pune-based startup Suryudey Plastic Electronics is using silver-carbon conductive inks to print flexible electronics directly onto fabrics. By replacing bulky copper wiring with screen-printed resistive heating elements, the company creates lightweight, durable heated garments and medical biosensors. The technology utilizes thermoplastic polyurethane substrates to ensure the electronics remain breathable and washable. This approach reduces reliance on imported rigid circuit boards and supports the localization of high-tech electronics manufacturing in India.

Interesting use of conductive inks. I wonder about the actual energy efficiency compared to traditional heating. If these are powered by standard USB banks, the total heat output is limited. The real test is the lifecycle. How many wash cycles before the silver-carbon ink starts to crack or lose conductivity?

Exactly. Durability is the main hurdle for wearables. Also, the article mentions defense applications with antennas. I would like to see the actual power draw specs. If this scales to industrial workwear, the battery density becomes the bottleneck, not the printing process.

The Make in India angle is the real driver here. Localizing the production of functional inks reduces supply chain risk and import costs. From a policy perspective, the iDEX initiative is a smart way to fund R&D by using defense procurement as a first customer for new materials.

Printing circuits instead of assembling them usually means less waste. It is a more additive process. Still, we need to know what happens to these garments at the end of their life. Separating TPU and silver-carbon inks from fabric for recycling sounds like a nightmare.
