High-sensitivity temperature sensor

Ultrasensitive microscale temperature sensing—flexible design possible

Overview

In biotechnology and healthcare, it is crucial to detect small temperature changes and heat generation with high sensitivity. This invention achieves remarkable temperature sensitivity by using ionic liquids with a high Seebeck coefficient in thermocouples, far surpassing conventional solid-state materials. The device employs a microfluidic chip, allowing the liquids to be physically separated but electrically connected, enabling flexible sensor structures. This system makes it possible to conduct ultra-sensitive temperature measurements even on curved and irregular surfaces, expanding the practical utility of temperature sensing well beyond what is possible with traditional solid-state sensors.
