Conductive & Piezo Ink
Applicable to In-Mold Electronics, wearable sensors, printed electronics, smart textiles, and more.
From piezoelectric ink that generates an electrical signal under pressure, to conductive ink that prints circuits, to piezoresistive ink that senses pressure as a change in resistance — a single printing process builds functional circuits and sensors.
In-Mold Electronics Ready
Combines with thermoforming and injection molding to embed circuits directly into plastic parts.
Pressure & Deformation Sensing
Piezoelectric and piezoresistive inks sense pressure, impact, and deformation as electrical signals.
Print-based Circuits
Screen printing alone builds conductive circuits and sensors directly onto the substrate.
Custom Formulation
Formulation and properties can be tuned to the application and required specs.
What kind of ink is PIEZO Ink?
A piezoelectric and piezoresistive ink that senses pressure, impact, and deformation as an electrical signal, together with a conductive ink that forms circuits by screen printing. Combined with thermoforming and injection molding, it enables In-Mold Electronics that embed circuitry directly into plastic parts.
- Which substrates can it print on?
- The silver conductive ink prints on PVC, PET, TPU, polycarbonate, acrylate, and polyurethane, and holds its performance stably before and after thermoforming.
- Is a low-temperature curing option available?
- The copper conductive ink cures at low temperature and is bendable, so it can also be used in In-Mold Electronics processes.
- Can the formulation be adjusted?
- Formulation and material properties can be tuned to the application and required specification. Share the substrate, printing method, curing conditions, and target resistance and we will review it.
01
In-Mold Electronics
Printed circuit graphics and functional inks survive thermoforming and injection molding intact, enabling In-Mold Electronics processes that embed sensors, LEDs, connectors, and wiring directly inside a plastic part.
- 1Screen Printing (graphics + functional inks)
- 2Thermoforming
- 3Injection Molding
Light Weight
Eliminates bulky PCBs and integrates sensors, LEDs, connectors, and circuitry into the plastic part — over 70% weight reduction.
Design Optimization
No dead space needed for wiring or connectors, capacitive switches can be designed freely, and design changes are quick to implement.
Cost Reduction
Simplifies assembly to a single connection point and cuts the number of components and raw materials — around 30% cost savings.
Higher Reliability
Fewer manufacturing steps and no moving parts to fail, with the whole circuit fully encapsulated for extra protection.
