Abstract

We propose a microfabrication technology for a flexible temperature sensor with a 100x100 mu m(2) sensing area and a probe length of 7 cm. We use a biocompatible new high temperature-resistant polyimide (U-Vamish-S, Ube, Dosseldorf, Germany) to embed a thin film platinum resistor as sensing element. The sensor is operational from 0 degrees C up to 400 degrees C with an accuracy of +/- 1 degrees C at high temperatures and has a time constant of 0.05 seconds. This sensor was designed for temperature characterisation of hot steam injected for thermo-ablation of tumors via a micro-needle.

Sensor

A sensor is a device that produces an output signal for the purpose of sensing a physical phenomenon. In the broadest definition, a sensor is a device, module, machine, or subsystem that detects events or changes in its environment and sends the information to other electronics, frequently a computer processor. Sensors are used in everyday objects such as touch-sensitive elevator buttons (tactile sensor) and lamps which dim or brighten by touching the base, and in innumerable applications of which most people are never aware.

Thermoset polymer matrix

A thermoset polymer matrix is a synthetic polymer reinforcement where polymers act as binder or matrix to secure in place incorporated particulates, fibres or other reinforcements. They were first developed for structural applications, such as glass-reinforced plastic radar domes on aircraft and graphite-epoxy payload bay doors on the Space Shuttle. They were first used after World War II, and continuing research has led to an increased range of thermoset resins, polymers or plastics, as well as engineering grade thermoplastics.

Polyimide

Polyimide (sometimes abbreviated PI) is a polymer containing imide groups belonging to the class of high-performance plastics. With their high heat-resistance, polyimides enjoy diverse applications in roles demanding rugged organic materials, e.g. high temperature fuel cells, displays, and various military roles. A classic polyimide is Kapton, which is produced by condensation of pyromellitic dianhydride and 4,4'-oxydianiline. The first polyimide was discovered in 1908 by Bogart and Renshaw.
