🔋 ❌ 700 million batteries are thrown away in the UK every year, with 4 billion across Europe.
A lot of those exist because an IIoT sensor needed replacing.
This problem only gets even worse at scale - More sensors, more maintenance schedules, more site visits to locations that were never designed for easy access.
What worse is, the labour and downtime costs often dwarf the cost of the sensor itself.
Energy harvesting takes batteries out of the equation entirely. A properly designed self-powered device runs on ambient vibration, heat, light or RF - with no replacements needed for 5-10+ years.
Data from real deployments presents 87-96% reduction in electronic waste over the device lifetime, and 70% fewer lifetime carbon emissions compared to battery-powered equivalents.
And it’s increasingly a compliance matter as well. EU Ecodesign regulation 2026/763 now requires new industrial wireless sensors to either use energy harvesting or demonstrate a 10-year battery life with recyclable chemistry.
Our engineers at ByteSnap Design have put together a 2026 handy guide covering:
- Feasibility calculations
- Wwreless protocol comparisons across LoRaWAN, Zigbee, BLE and NB Cellular
- and a rail industry case study where we deployed a system running on piezo, solar and wind - with no external power and no maintenance access required.
If you’re evaluating energy harvesting for your IIoT application, the feasibility section is the most useful place to start.
