Objectives

What SafeDrop sets out to do

Integrate the platform

Co-localise MZI photonics and TFT electronics into a 32-cell K-cell array on a CMOS-compatible process.

Functionalise & sense

Deposit a cross-responsive coating library via ESJET printing to produce rich chemical fingerprints.

Decode with AI

Develop AI/MIMO models that fuse optical and electrical channels for high-accuracy classification.

Validate in the field

Demonstrate across water, health and food use cases at TRL 5, with an exploratory TRL 4 air-quality demonstrator.

Drive down cost

Target a disposable cartridge ≤ €10 (≤ €5 at scale) with a <1 W system power budget.

Open the ecosystem

Release open PDKs, open hardware and standards contributions to grow a wider community.

Roadmap

A 48-month journey

Months 1–3 · In progress

Project launch

Kick-off meeting (June 2026), consortium alignment, and website & communication channels launch (August 2026 M3).

Year 1 · Foundations

Design & materials

Photonic/electronic co-design, coating-material development and first single-cell demonstrations.

Year 2 · Integration

Submodule validation & ESJET

4/8-unit submodule validation (IL2) and scaled ESJET deposition.

Year 3 · Intelligence

32-cell integration & AI/MIMO

Integrate the full 32-cell prototype, commission dual rigs, train and validate AI/MIMO models, and build the full prototype system.

Year 4 · Validation

Demonstrators & validation

Field-validate across the four case studies at TRL 4–5; photonic techniques reach TRL 7.
