1. Industrial IoT (IIoT) – Wireless Sensors for Predictive Maintenance

What It Is

In factories and industrial plants, wireless sensors monitor equipment health—tracking vibration, temperature, pressure, and more. These sensors enable predictive maintenance, helping companies avoid costly downtime by detecting issues early.

Why Supercapacitors Shine

Industrial sensors often operate in remote locations (e.g., inside machinery or on high ceilings) where replacing batteries is a logistical nightmare. They also need to transmit data in short bursts, typically requiring 50–200 mA for 10–50 ms. Supercapacitors deliver this power instantly and recharge quickly, often using energy harvesting from ambient sources like machine vibrations or heat.

How It Works

Imagine a sensor on a CNC milling machine. It uses a piezoelectric harvester to convert mechanical vibrations into energy, storing it in a supercapacitor. Every few minutes, the supercapacitor discharges a 100 mA burst to send vibration data wirelessly to a central system. With over a million cycles, the supercapacitor can operate for years without maintenance.

Benefits

• Reduced Downtime: No need to halt production for battery swaps.
