Case studies

Products built on our technology and running in the field today, across industrial and commercial sites in Brazil, North America and Europe.

Predictive maintenance on motors

Sensor Spectra

The problem: Monitoring vibration and temperature across a plant means hundreds of sensors on motors and rotating assets — and hundreds of batteries to replace, often in places that are hard or unsafe to reach.
The solution: KIWI harvests the reactive electromagnetic field and the vibration of the motor itself, and keeps the sensor’s battery charged.
The result: About 5 mW delivered continuously: no cable to run and no battery to replace.

Industrial data acquisition

The problem: Bringing data out of distributed industrial systems usually means running power and signal cables to every point.
The solution: KIWI combines the electromagnetic energy of the industrial environment with the available light to power the node.
The result: About 30 mW delivered continuously: data collected across distributed systems, fully wireless.

Self-sustaining public lighting

The problem: Lighting on poles, highways and tunnels needs energy and maintenance in places where both are expensive.
The solution: Solar-powered intelligent luminaires in which KIWI manages the energy between panel and batteries, with impedance matching and MPPT.
The result: More of the panel’s energy stored in the batteries: self-sustaining lighting infrastructure.

Long-range connectivity off the grid

The problem: A gateway has to sit where the sensors are — and that is rarely next to a power outlet.
The solution: A LoRa to 4G and Wi-Fi gateway in which KIWI, with impedance matching and MPPT, gets the most out of a small solar panel.
The result: A gateway that runs on a small solar panel and sends data to the cloud over Wi-Fi and 4G, with no power line.

Temperature monitoring without cables

The problem: Temperature has to be measured at many points, and each point would need a cable or a battery.
The solution: KIWI harvests the reactive electromagnetic field and the vibration of nearby motors, and keeps the sensor’s battery charged.
The result: About 2 mW delivered continuously: temperature sensing with no cables and no battery to replace.
