21 September 2026Battery-Free BLE Tracking: Why the Ambient Energy Is Never There When You Need ItBattery-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.24 August 2026Battery-Free Sensor Lifetime: What a Forty-Year Asset Actually DemandsBattery-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.17 August 2026Battery-Free Sensor Sampling Rate: What Your Power Budget Actually AllowsA 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.2 June 2026Does Your Sealed, Inaccessible Asset Actually Need Battery-Free? A Practical FilterA three-question filter to tell whether your monitoring application really needs battery-free sensing, or whether a battery or a wire is simpler, cheaper.10 February 2026Inside a Battery‑Free Sensor: Power Path, Storage, and Duty CyclingBattery-free sensor design: the power path, storage sizing and duty cycling, plus UHF RFID, BLE burst and NFC tap-to-measure patterns that work in practice.3 February 2026The Rise of Zero‑Maintenance Sensors: A Game Changer for IndustryZero-maintenance sensing is a strategy, not one technology: battery-free where a reader reaches, batteries for autonomous updates, wires for real time.27 January 2026Why RF Energy Harvesting Beats “Natural” Sources for Reliable IoT SensorsWhy RF energy harvesting from a RAIN RFID reader beats indoor light and vibration when you need a reliable, on-demand measurement from an industrial sensor.10 December 2025What “Battery‑Free” Really Means in IoT — Clearing the ConfusionBattery-free does not mean no energy. The sensor harvests energy on demand, often from sub-1 GHz RF, stores it briefly, measures and sends the data back.26 November 2025Top 5 Energy Harvesting Techniques for IoT DevicesSolar, thermoelectric, piezoelectric, RF and kinetic: the five main energy harvesting techniques for IoT devices, and how each one works.30 September 2025Energy Harvesting: Powering Wireless Sensors Without BatteriesHow energy harvesting powers wireless sensors without batteries, and why we focus on RF: it is the energy you can guarantee, even in dark, closed spaces.24 September 2025Designing Battery-Free Wireless Sensors: Challenges and SolutionsUltra-low power, variable energy, timing, power budget and size: the five challenges of designing battery-free wireless sensors, and how to address them.29 November 2024Energy-Limited Systems vs. Power-Limited Systems: A Comparative InsightEnergy-limited and power-limited systems hit different limits. The difference, and why it matters when you design battery-free, energy harvesting sensors.8 October 2024Welcome to Our Blog: Exploring the Future of Wireless and Battery-Free SensingThe Kliskatek blog on wireless and battery-free sensing: energy harvesting, sensor design, applications and practical guides from the team that builds them.
