In July, I took our son to a soccer tournament. It was a hot summer day with temperatures above 30°C—perfect conditions for exciting games, but also a challenge for both people and technology. The children gave it their all, and while they were resting in the shade between games, I noticed a boy from another team: he was wearing a CGM sensor on his upper arm – a device for continuous glucose monitoring that wirelessly sends his readings to an insulin pump.
But suddenly, a technical problem arose: the pump was no longer responding as expected. The glucose levels were not being processed correctly, and insulin delivery stalled—a stressful situation for both the boy and his mother. Before physical symptoms such as dizziness and difficulty concentrating could set in, his mother acted swiftly. Using a manual meter and insulin syringes, she was able to stabilize the situation—and the boy was back playing shortly afterwards.
What went wrong? The insulin pump had overheated—a problem that can occur at high temperatures.
Why heat is a challenge for insulin pumps
Insulin pumps are complex medical devices whose function rely on numerous electronic components. In strong sunlight or high ambient temperatures, these sensitive components can be pushed to their limits:
- Microcontrollers and memory chips:- control dosage and time functions; – heat-sensitive
- Sensors and wireless modules:- Bluetooth/NFC connections may become unstable.
- Displays and controls:- can respond slowly or incorrectly.
- Batteries:- may lose capacity in hot conditions.
- Frequency control products:- Quartz Crystals and Oscillators can clock inaccurately, affecting insulin delivery.
Insulin itself also loses its effectiveness at temperatures above 30°C—a medical risk that should not be underestimated.
Reliability starts with the component – Jauch makes the difference
High-quality, temperature-stable components are crucial to ensure that insulin pumps function reliably, even under extreme conditions. Jauch offers precisely this level of quality, making a vital contribution to the everyday safety of people with type 1 diabetes.
Battery solutions from Jauch
- Lithium polymer and lithium ion batteries for pumps and receivers:- with integrated battery management systems, flexible design, and excellent temperature stability—for maximum safety even in hot conditions.
- Lithium button cells for CGM sensors:- high energy density, long-lasting, and reliable—ideal for continuous monitoring.
Frequency control products from Jauch
- Miniature quartz crystals from the JXS series (e.g. JXS10, JXS11): ensure stable Bluetooth/NFC communication—even with temperature fluctuations.
- (VC)TXCOs: Temperature-compensated oscillators for maximum frequency stability—even under extreme conditions.
- Watch quartz crystals such as JTX110: enable precise timekeeping – essential for correct insulin delivery
- WA quartz crystals (Wireless Application): pre-aged and with minimal frequency deviation over 10 years – ideal for medical devices in continuous use.
Back to the sports field – technology that builds trust
The incident on the shows that technology can reach its limits—but with the right components, a lot can be avoided. For parents and children living with diabetes, this means being prepared, but also focusing on quality. Manual meters and insulin syringes are useful in hot weather—but it’s even better if the technology doesn’t fail in the first place.
Jauch stands for quality, reliability, and safety – even at 30°C and above. With the right batteries and frequency components, Jauch supports the development of modern medical devices that help people with diabetes to lead active and safe lives – on the soccer field and beyond.
