Thermometers Using Physical/Chemical Changes TRIZ Cases
- Battery Thermal Runaway Prevention via Endothermic Separator
A battery thermal management system uses a low melting point separator layer to trigger an endothermic reaction that absorbs heat and prevents thermal runaway.
- Optical Fiber Measurement Device Brillouin Gain Spectrum Segmentation
A measurement device obtains two Brillouin gain spectra using different incident light spectral widths to detect optical fiber characteristics.
- Fiber Optic Smoke Detection for Aircraft Fire Monitoring
Replacing bulky sensors, this optical system analyzes scattered light to monitor fire conditions in high airflow areas while reducing false alarms.
- Microfluidic Temperature Measurement via Fluorescence Diffusion
A microfluidic device determines fluid temperature by reading diffusion signals from a fluorescent agent using an optical camera system.
- Watercraft Bubble Curtain for Marine Noise Damping
Hull-integrated sub-hulls create a bubble curtain that attenuates acoustic waves from piling, reducing noise pollution.
- Thermochromic Paint Layer for Table Temperature Monitoring
Thermochromic paint layers on a heating table change color to resolve the contradiction between visual temperature monitoring and device complexity.
- MRI-Based SAR Determination via Thermal Inversion
Thermal inversion of the bioheat equation calculates local and spatially averaged specific absorption rate, eliminating mechanical probe translation delays.
- Direct-Printed Chromic Indicator Arrays for Component History Monitoring
Pre-printed indicator arrays replace time-consuming manual inspections by detecting energetic events and temperature ranges via colorimetric responses.
- Creatine CEST Imaging for Noninvasive Brain Temperature Measurement
A creatine chemical exchange saturation transfer method enables noninvasive absolute temperature measurement with high spatial resolution.
