Backup battery monitoring: a sensor with its own cell drains the reserve it watches, while a passive sensor takes its energy from the reader instead

Backup Battery Monitoring: Why You Cannot Put a Battery Inside to Watch a Battery

2026-10-12 by Mikel Choperena

Backup battery monitoring has a contradiction at its centre: testing the reserve costs the reserve. What a passive reading changes, and when not to bother.

Prototype to production: one unit that works becomes five hundred that all have to work, so every tuned value turns into a window with a worst case

From Prototype to Production: What Changes When One Unit Becomes Five Hundred

2026-10-05 by Mikel Choperena

The prototype to production step is not a scaling problem. What changes in test, tolerances, supply and conformity, and the five questions to ask first.

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

2026-08-17 by Mikel Choperena

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.
