LED powered by sweat through stretchable biocell

Recharging Wearables: Fabric as Power

As we become ever more dependent on smartphones, tablets, and digital watches, recharging our batteries has gone from a metaphorical refresher to an all too literal imperative. Researchers at UC-San Diego, however, are pointing to a new way of addressing this problem beyond endlessly looking for outlets in all the wrong places: powering devices with your own sweat.

From the abstract in the latest issue of Energy and Environmental Science:

This article describes the fabrication, characterization, and real-life application of a soft, stretchable electronic-skin-based biofuel cell (E-BFC) that exhibits an open circuit voltage of 0.5 V and a power density of nearly 1.2 mW cm−2 at 0.2 V, representing the highest power density recorded by a wearable biofuel cell to date.... When applied directly to the skin of human subjects, the E-BFC generates ∼1 mW during exercise. The E-BFC is able to power conventional electronic devices, such as a light emitting diode and a Bluetooth Low Energy (BLE) radio. This is the first example of powering a BLE radio by a wearable biofuel cell. Successful generation of high power density under practical conditions and powering of conventional energy-intense electronic devices represents a major step forward in the field of soft, stretchable, wearable energy harvesting devices.

As one of the researchers explained to New Scientist, "We’re now getting really impressive power levels. If you were out for a run, you would be able to power a mobile device." What's more, this could also make be used to power wearable sensors to gather and send health data. As fabric technology continues to advance, we could see activewear textiles valued not just for their capacity to evaporate sweat, but to harness it.

Of course, with great power comes great responsibility, and the legal ramifications of recharging through wearable fabric run from skin interactions, FDA regulation, and data security to more tangential risks of litigation. And this just touches the surface as to the ramifications of textile tech -- we'll be exploring these issues and more at our upcoming Fashion Law Bootcamp: Special Edition in San Francisco and Cupertino!

Name game: G-III swaps out Ivanka labels

Was it illegal for G-III to replace Ivanka Trump labels with those of another brand? Lauren Sherman asks Professor Scafidi for The Business of Fashion:

“US textile product labelling laws allow substitution of labels, so long as the entity making the substitution is identified on the new label and keeps records for three years,” explained Susan Scafidi, professor of fashion law at Fordham Law School and founder of the Fashion Law Institute. “This is mostly for supply chain tracking reasons. All of the other required information on the label — fibre content, country of origin, etcetera — must be maintained.”

...

“If the original label [is replaced] with that of a third party unaware of the substitution, the [responsible party] would be liable to the third party,” Scafidi says. “All of this derives historically from the law of fraud.”

The 9th Circuit's ruling in Unicolors v. Urban Outfitters is interesting not only for its discussion of the proper standard for summary judgment in a copyright infringement case, but for its glimpse into Urban Outfitters' design process. The 9th Circuit concluded that this process was evidence of recklessness -- a revealing example of why it's essential to understand that in this age of ubiquitous tech and far-reaching discovery, the image of corporate enterprise as an impenetrable black box has all but disappeared. unicolors-urban-outfitters-9th-circuit
