IoT stories that inspired us in 2025
Innovation - December 15, 2025
As connected devices continue to reshape our world, 2025 has brought a fresh wave of innovation powered by smart sensing, longlasting batteries, and bold thinking.
From security to agriculture, healthcare to monitoring environmental risks, here are five standout IoT stories from Saft clients this year - real-world solutions that are energizing change.
Securing self-storage like never before
Self-storage is a booming business.
Globally, it’s worth tens of billions, and U.S. facilities alone store over 1.7 billion square feet of space.
But despite that scale, many units rely on simple padlocks and keys. PTI Security Systems (part of Assa Abloy) changed that with their ProEdge Smart Latch, a high-tech, IoT-enabled locking system tailored for self-storage.
At the heart of it all is a Saft LM17500 battery giving around three years of life. Rather than short-lived power cells, this durable battery enables hundreds of locking/unlocking requests without the need for frequent maintenance.
A smart step for liquid gas
LPG (liquified petroleum gas) powers everything from cooking to heating, especially in regions where cleaner energy options are scarce.
Ragasco, a Norwegian company has reinvented the gas cylinder with its Linktra® Smart cylinder: a composite, IoT-connected container that senses how much gas is left and when a refill is needed.
Using capacitive sensors, these “smart cylinders” detect not only fill levels but also anomalies such as illegal refills. Their data links back to an app, giving distributors and end users better visibility.
Bringing transparency to seed distribution
Seed is big business in more ways than one.
The seed industry is worth over US$50 billion, and it is essential for food security. Yet data on the location, condition, and usage of seed has historically been limited.
That’s changing thanks to QuarterPoint, a partnership between Seedbox Solution and Trace Engineering.
They built the SmartBox, an IoT-enabled container that monitors environmental conditions, location and fill level (even whether the contents are in transit). The data flows into a dashboard that allows producers to track fleet-wide trends, dealers to understand storage health, and farmers to check on individual boxes.
That insight helps reduce waste, protect quality, and optimize logistics. And the vision doesn’t stop at seeds as the SmartBox platform could be adapted for other high-value, returnable packaging.
A toilet seat that helps the heart
Sometimes innovation comes in the most surprising form.
German company Hamberger Medical, in collaboration with the Fraunhofer Institute, has created a smart toilet seat that monitors heart rhythms using a six-lead ECG. Built into an object that billions of people already use daily, the seat can detect atrial fibrillation - a common heart rhythm disorder that increases stroke risk.
By capturing data passively and regularly, the toilet seat offers a low-friction way to monitor health. A clinical study confirmed that its performance is comparable to gold-standard medical devices.
The team is now exploring adding other non-invasive metrics to the seat including blood pressure, oxygen saturation, and even blood sugar.
Combating heatstroke with smart sensing
As global temperatures climb and heat waves become more frequent, Tanita, a company known for its precision health instruments, has turned to IoT to help prevent heat-related illness.
Powered by Saft batteries, Tanita’s sensors measure temperature, humidity, and other risk factors for heatstroke.
This data allows for early alerts that can help with pre-emptive interventions (whether that’s moving to shade, rehydrating, or reducing exertion). For vulnerable populations in particular, this proactive risk mitigation can help to save lives.
