Speculative direction · concept study only.
Current BioEchem zones are field-a (outdoor) and greenhouse-1 (controlled
environment). Cold-chain is a forward-looking application area, not on the active 2026 roadmap,
and not commercially available. Page kept as a partnership conversation piece.
If the same biological sensor that proves a flood event in a greenhouse can be sealed into a shipping carton, the receiver gets a signed event log of the package's journey — temperature excursions, thaw events, jolt, light. Receivers verify with a phone scan, no proprietary scanner. This is a future direction, not a shipping product — but the underlying signature chain, the power envelope, and the partner verifier are real today.
One sensor, one biological tag, one signed event log per package.
Every Cold-Chain Witness shipment ends with a verifiable proof bundle, not a vendor's word.
Power: 3 V at 1 mA or lower — ≤3 mW class. Biological cell drives the transitional sensor; the MCU is on its own power.
Materials: no rare materials. Supply-chain clean, ESG-aligned out of the box.
Sync model: events stored locally on the MCU; uploaded at each connectivity checkpoint along the route — not a live BLE beacon. This is what the power envelope supports and what pharma + recall workflows actually consume.
High-value or regulated shipments where "we tracked it" is not enough.
Tell us what you ship and what receivers ask of you today — we will scope a pilot of 5–25 tags at no commitment.
