Towards Hand Model with Integrated Multichannel Sensor System for Thermal Testing of Protective Gloves

Abstract

This paper deals with the development of a temperature sensor system consisting of multiple temperature sensors integrated into a model of a human hand and a system for data collection, processing and 3D visualization. The measuring part of the system uses temperature sensors TMP05, which enable daisy chain serial connection. The individual chains are then connected to the microprocessor. The microprocessor controls the temperature measurement and sends data to the computer, where data is processed, evaluated and visualized. The temperature sensors are mounted on flexible printed circuit boards which are placed into the human hand model and subsequently fixed by a UV curable adhesive. The model of the human hand is designed in accordance with the standard models for the production of rubber gloves and it is made on a 3D printer of polyamide PA6 filled with short carbon fibers. The final version of the system will have approximately two hundred sensors, which will be concentrated mainly in the area of fingers and back of the hand.
