Design of a Thermoelectric Energy Harvesting Module for a Wireless Pressure Measurement in Vehicles

A thermoelectric energy harvesting module for the pressure measurement of air induction system of heavy duty vehicles is designed. A positive contribution for cable complexity, fuel consumption and vehicle performance is intended by creating a sensor node after the air filter. A sensor node basically measures the pressure drop before the compressor inlet through air filter of a vehicle and transmits the pressure wirelessly to the engine control unit (ECU). System is capable of generating electrical energy by means of a thermoelectric generator to the sensor node for its life time with a 1Hz sampling frequency.
