Batteries and Fuel Cells

31.8K
A battery is a galvanic cell that is used as a source of electrical power for specific applications. Modern batteries exist in a multitude of forms to accommodate various applications, from tiny button batteries such as those that power wristwatches to the very large batteries used to supply backup energy to municipal power grids. Some batteries are designed for single-use applications and cannot be recharged (primary cells), while others are based on conveniently reversible cell reactions that...

DC Battery

1.5K
A conductor needs to be a component of a path that creates a closed loop or full circuit to have a continuous current flowing through it. A current starts to flow if an electric field is created inside an isolated conductor that is not part of a full circuit. The conductor quickly develops a net positive charge at one end and a net negative charge at the other. These charges generate an electric field opposite the direction of the applied electric field, which reduces the current. Eventually,...

Pulse Oximetry

1.6K
Pulse oximetry, or SpO2, is a non-invasive method for continuously monitoring arterial oxygen saturation (SaO2). This procedure involves attaching a probe or sensor to the patient's fingertip, forehead, earlobe, or nose bridge. The sensor works by detecting changes in oxygen saturation levels through light signals generated by the oximeter and reflected by the pulsing blood under the probe.
Purpose
Average SpO2 values are greater than 95%. If the readings fall below 90%, it indicates that...

Area of Science:

  • Environmental Health Engineering
  • Sensor Technology
  • Internet of Things (IoT)

Background:

  • Carbon monoxide (CO) poisoning is a significant household risk in Taiwan, often linked to natural gas water heaters.
  • Existing safety measures may lack comprehensive real-time monitoring and immediate alerting capabilities.

Purpose of the Study:

  • To develop and evaluate a wireless, batteryless intelligent CO sensor system for enhanced safety around natural gas water heaters.
  • To provide early warnings for dangerous CO levels, mitigating poisoning incidents in residential and industrial settings.

Main Methods:

  • A micro-hydropower generator powers a low-consumption CO sensor (COSWOB), eliminating the need for batteries.
  • The COSWOB monitors ambient CO levels and transmits data to an intelligent gateway.
  • The system triggers local alarms, Wi-Fi alerts, and mobile notifications upon detecting dangerous CO concentrations.

Main Results:

  • The COSWOB operates efficiently with minimal power consumption (~13 mW) using micro-hydropower generation.
  • The integrated system effectively monitors CO levels and provides multi-channel alerts to warn individuals indoors and outdoors.
  • The proposed solution demonstrates potential for both home safety and industrial leak detection.

Conclusions:

  • The wireless, batteryless CO sensor system offers a novel and effective solution for preventing CO poisoning incidents.
  • This technology enhances safety for natural gas water heater usage and has broader applications in industrial monitoring.
  • The system's ability to provide timely, multi-platform alerts significantly improves early warning capabilities.
