Discover the key takeaways and what you can apply right away

Memory is the game changer at the endpoint: Ultra-thin thin-film/solid-state and printed zinc enable low-maintenance tags/labels – compatible with antennas, chips, and form factors.
Harvesting requires buffers and power management: light/RF/motion provide energy irregularly; only with micro-storage, peak coverage, and clean control does it become suitable for field use.
RFID vs. BLE vs. LPWAN determines the energy budget: Peak currents, sleep modes, and duty cycles determine whether battery-free, hybrid, or battery-first really works.
Design rules trump capacity: Package size, transmission interval, event triggers, antenna efficiency, and firmware strategy have a greater impact on runtime and sustainability than "more mAh."

Solid-state batteries for BLE labels

Solid-state batteries represent a real technological leap forward for BLE labels: longer runtime with minimal energy consumption.
Instead of frequent battery changes, operating times of many years are realistic – even with large quantities. At the same time, safety is increased because solid electrolytes significantly reduce the risk of leakage or overheating.
Compact, flat designs enable new label designs that can be integrated inconspicuously. The result: low-maintenance tracking with higher availability and noticeably better operating costs.
Target markets are IoT, MedTech, and consumer electronics, with a particular focus on wireless IoT. Currently, the greatest potential lies in rechargeable BLE labels, LoRaWAN trackers, and other devices with energy harvesting.
The result is low-maintenance, durable, and scalable solutions for broad use.
