Smart materials application on high performance sailing yachts for energy harvesting [PDF]

open access: yes, 2013
Piezoelectric patches are bounded on a keel bulb in order to harvest vibration energy by converting electrical output. Unsteady computational fluid dynamics method is also used to find the structural boundary condition such as the hydrodynamic pressure ...

Effect of Inhomogeneous Temperature in Chip‐Scale Infrared Thermal Sources: A Revisited Blackbody Radiation Formula with Experimental Validation

open access: yesAdvanced Electronic Materials, EarlyView.
Revisited Black‐body radiation formula accounting for nonuniform temperature is proposed for calibration of planar thermal light sources. Calibration of optical power is based on measurement of the highest and lowest temperatures. Abstract Miniature and low‐cost light sources are highly desirable for numerous optical microsystems.

The Cable to the Moon: Veritasium's Light Bulb Experiment in Low-Cost Miniature Form [PDF]

open access: yesarXiv
In a popular YouTube video by the channel Veritasium, the following question is posed: Imagine you have a giant circuit consisting of a battery, a switch, a light bulb, and two wires which are each 300,000 km long. That is the distance that light travels in one second.

High‐Performance n‐type Organic Thermoelectric Aerogels Toward Flexible Energy Harvesting and Sensing Devices

open access: yesAdvanced Electronic Materials, EarlyView.
An n‐type organic thermoelectric aerogel PB@CNF, based on PBFDO, is fabricated by a two‐step freeze‐drying process with cellulose nanofiber (CNF) as substrate. The aerogels can be used not only as temperature sensing and piezoresistive sensing, but also to form a flexible organic thermoelectric generator with the p‐type aerogel (PH@CNF) based on PEDOT ...

When do firms sell high durability products? The case of light bulb industry [PDF]

open access: yesarXiv
This study empirically investigates firms' incentives on the choice of product durability, and its social optimality, by developing a dynamic structural model of durable goods with forward-looking consumers and oligopolistic multi-product firms. Based on the observations of the light bulb market, it specifies a model where firms produce multiple ...

High‐Performance Conductive Elastomers Based on Deep Eutectic Solvents and Polyvinyl Alcohol for Flexible Monitoring Sensors

open access: yesAdvanced Electronic Materials, EarlyView.
A novel conductive elastomer is developed by incorporating deep eutectic solvents into a PVA/Polyacrylic Acid (PAA) network. The synergistic effects of dynamic hydrogen bonds, ionic interactions, and chemical crosslinking result in a highly flexible and dense polymer structure, while the integration of sodium chloride ensures excellent conductivity and
