Abstract
Portable electronic devices are comprised of a secondary battery or DC charge source and due to abrupt
micro-current alteration and short circuit overcurrent; fire and explosions can happen. A protecting device
should steadily cater to phenomena like overcurrent situation and micro-current alter state to avoid any
hazardous circumstances. In this work, high current protecting multi-layered thin film triode micro fuses
are designed and simulated using the MEMS-based tool of COMSOL Multiphysics software and then
the device has been fabricated using the RF magnetron sputtering method and then electrically analyzed
to compare between simulation and experimental data. To design a low melting point-based alloy for fuse
element and negative temperature coefficient (NTC) based metal oxide functions as a heater material and
to control high current high power is the primary purpose of this investigation. A Lead-tin (90Pb:10Sn)
alloy has been employed as the low melting point-based fuse element and tungsten oxide (WO3) is
integrated with the layer as a self-heating resistor material. The electro-thermo-mechanical behavior is
assessed, and a three-dimensional time-dependent modelling and simulation technique has been
performed in both steady state and transient conditions with varying some physical and electrical
parameters. The triode fuse simulated data shows that around 5.6A current the device temperature reaches
to nearly 300°C and thus the triode fuse works by blowing the fuse. More importantly, after fabricating
the device experimentally using nanofabrication technique, electrical characterization has been performed
and experimental data almost provides similar result. The triode micro fuse device let current flow until
5A current, and the temperature distribution of the device follows simulated phenomena, thus blows at
5A current. This device completely suited for portable secondary battery protection system where current
rating islike this device’s rated current. This advanced research will facilitate a new class of portable micro
fuse to be assembled with triode mechanisms in real-time technology for self-control protector.
