Key Points
This research aims to improve energy harvesting and temperature sensing using Bi2Te3-based thermoelectric devices with phase-change materials.
Utilized direct ink writing (DIW) for 3D printing of a Bi2Te3 device.
Incorporated a phase-change material (PCM) heat sink to enhance thermal management.
Integrated the device into a wireless temperature alarm system for IoT applications.
Achieved a 150% increase in output power due to enhanced thermal gradient.
Successfully demonstrated integration into a self-powered IoT temperature alarm.
Abstract
A DIW-printed out-of-plane Bi 2 Te 3 -based device with a 3D-printed PCM heat sink increased the thermal gradient and boosted output power by 150%. It was integrated into a wireless temperature alarm as a self-powered IoT solution.
