RFID read point design: the window a moving asset gets inside the field is set by speed and geometry, and barely by reader power

RFID Read Point Design: What Decides Whether a Moving Asset Gets Read

2026-09-28 by Mikel Choperena

RFID read point design decides whether a moving asset gets read. Why the window is time and not distance, what the line can give you, and five questions.

Battery-free BLE tracking: ambient energy is plentiful on average and absent where a lost asset sits, which is why working deployments bring their own energy

Battery-Free BLE Tracking: Why the Ambient Energy Is Never There When You Need It

2026-09-21 by Mikel Choperena

Battery-free BLE tracking works on average and fails on the day an asset goes missing. Why ambient energy is not a plan, and what to ask before you build.

The four questions that decide aerospace battery-free sensors: what the measurement replaces, who reads the number, what already goes past the asset, and how long the reading has to stay true

Sealed, Inaccessible, Mission-Critical: Four Questions Aerospace Battery-Free Sensors Have to Answer

2026-09-14 by Mikel Choperena

Your asset is sealed, inaccessible and mission-critical. Four questions decide aerospace battery-free sensors, and none of them is about access.

CMMS integration for battery-free data: the four steps that turn a reading into a work order, identity, absence, reduction and the work order itself

From Sensor to Work Order: CMMS Integration for Battery-Free Data

2026-09-07 by Mikel Choperena

CMMS integration is where battery-free sensor projects are decided. What a reading needs to carry before it can open, prioritise and close a work order.

Four costs that decide what custom battery-free sensors can measure: excitation, settling time, analogue conditioning and calibration

Beyond Temperature: What Custom Battery-Free Sensors Can Actually Measure

2026-08-31 by Mikel Choperena

Custom battery-free sensors go past temperature: pressure, load cells, pH and e-ink, what each one really costs, and where the honest limit is.

Battery-free sensor lifetime inside a sealed high voltage asset, on a forty year timeline: a coin cell lasts five to ten years, the reader outside the enclosure gets replaced several times, and the real design target is the access interval, the moment somebody next opens the enclosure, next to the five mechanisms that age once the cell is gone.

Battery-Free Sensor Lifetime: What a Forty-Year Asset Actually Demands

2026-08-24 by Mikel Choperena

Battery-free sensor lifetime is not battery life with the cell removed. What really ages in a sealed HV asset, and why the access interval sets the spec.

A battery-free sensor sampling rate that collapses at a threshold: as the power reaching the device falls towards the leakage current, the interval between readings runs away and the device stops reporting altogether, shown next to the arithmetic of a 150 µJ session, about 30 seconds at 10 µW, about 3 seconds at 100 µW and under a second at 1 mW.

Battery-Free Sensor Sampling Rate: What Your Power Budget Actually Allows

A battery-free sensor sampling rate is arithmetic, not a setting. The three inputs, the leakage cliff, and four levers when the spec asks for more.

A cross-domain engineering case study of a production test bench split between two suppliers: the hydraulics specialist owns the loop and the motion controller, the systems team owns hardware control, the measurement chain, the data model and the verdict, and the seam between them has to settle command authority, the reference clock, units and signs, what a test is, fault handling and who owns the record.

When Splitting Is the Right Call: A Cross-Domain Engineering Case Study

A cross-domain engineering case study: why we split a production test bench between two suppliers, and why the seam decided the whole project.

The three questions that qualify a maintenance round for NFC sensor tags: does somebody already walk the route, does the value change more slowly than the round interval, and can a person reach the point with a phone. A tap removes transcription and proves presence within about two centimetres, but the tag harvests energy only while the phone field is present, so nothing is recorded between rounds.

NFC Maintenance Rounds: When to Put Sensors on Your Route

NFC maintenance rounds do not replace the walk, they change what it produces. Three questions decide whether your inspection route is a candidate
