Functional surfaces possible

Printed electronics
for every surface

Electronics deposited like ink rather than assembled from components. Thinner, lighter, and adaptable to any substrate.

01
Conformal Electronics
Electronics that conform to any surface: curved, irregular, or three-dimensional. Using screen-printing and inkjet deposition, we place functional circuits directly onto substrates that conventional PCBs can never reach. The electronics become part of the object.

E-Textiles & Smart Fabrics
Not sewn in, not clipped on — printed directly onto the textile. Our conductive ink processes produce heaters, sensors, and antennas thinner than a human hair, adding no perceptible weight or stiffness. Breathable, lighter, and far thinner than embroidered e-textiles.

Heaters
Ultra-thin resistive heaters screen-printed at 50 micrometres. Flexible, conformal, and stretchable — they adapt to any surface without cracking. Available with high optical transparency. Precise thermal control via NTC thermistors and PID algorithms.

Antennas & Sensors
Transparent silver nanowire antennas screen-printed onto flexible PET substrates, enabling connectivity that is invisible, lightweight, and conformal. Combined with biosensing capabilities, our printed sensors open new form factors for medical wearables and IoT devices.

The beginning

Suryudey was founded on a single question: why do electronics have to be rigid? Conventional electronics are built from components soldered onto stiff boards. That works for a laptop. It does not work for a jacket, a curved medical sensor, or an antenna that needs to be transparent and conformal.

The opportunity was to treat electronics the way a printer treats ink, depositing function directly onto any surface, any shape. From that premise, Suryudey was incorporated in Mumbai in 2021.

What printed electronics means

Printed electronics is an emerging manufacturing field where functional inks (conductive, resistive, semiconducting) are deposited onto substrates using processes borrowed from the printing industry: screen printing, inkjet, gravure. The result is electronics that are thin, lightweight, flexible, and manufacturable at scale.

Applications span medical biosensors, industrial heating elements, transparent antennas for IoT devices, and smart textiles. The common thread is that the electronics disappear into the object.

People ask us what we are

An antenna company? A heated clothing company? A medical devices company? The honest answer is: we are all of these, and none of these. We are a printed electronics manufacturer. The applications are what happens when you give the technology to the right problems.

Our B2B business, operating as SPEZL, serves startups, research institutes, and established companies who need customised printed electronics. Our consumer brand, iðoona, is our own proof of concept: what happens when we apply the technology to the problem of personal warmth.

Two brands.
One technology.

The same silver-carbon printing process powers both our B2B manufacturing business and our consumer heated wearables brand.
