Around 1780: "An anonymous British printmaker, perhaps from Birmingham, issued a satire of mechanization and factories occuring during the Industrial Revolution, in the form of an imaginery 'New Shaving Machine, whereby a number of persons may be done at the same time with expedition, ease, and safety.'"

Around 1825: "British illustrator and caricaturist Robert Seymour... issued Shaving by Steam... In his creation of this print Seymour was undoubtedly inspired by an earlier anonymous print entitled 'New Shaving Machine.' The sign above the door on the right in Seymour's image announces 'Patent Shavograph!!!'" (text from historyofinformation.com)
Oct 1960: English comedian Eric Sykes built a working "New Shaving Machine" (modeled from the 1780 print) on a pilot show for a proposed television series called 'Brainwaves.' The premise of the show was recreating strange old-time inventions. However, the show never aired.
In 1963 the Mansfield News-Journal predicted that, "Some day, Mansfielders will carry their telephones in their pockets."
So when did the first phone debut that could be carried in a pocket? Depends on the size of the pocket, I guess. But I think it was arguably the Motorola StarTAC, that came out in 1996 — 33 years after the News-Journal prediction.
The idea was that a person could pair their smartphone with the wig and then receive "tactile feedback" (such as a vibration) when they received a text or email.
But that was just the tip of the iceberg. The SmartWig had many more potential uses, such as the following:
During a presentation the user may, for example, move forward or backward through presentation slides by simply pushing the sideburns, i.e. by pushing the one or more buttons. Thus, the user can control the presentation slides simply by natural behavior like touching side burns. Additionally, the wearable computing device may comprise a laser pointer that is arranged in or on the wig. The laser pointer may, for example, be arranged on a forehead part of the wig, so that the user may point out relevant information on the projected slide in the above-explained presentation mode.
I imagine it would be a lot more difficult to aim a laser pointer with your head rather than your hand. Not to mention it would look bizarre.

Researchers at Johns Hopkins have invented (and patented) a mushroom-powered air cooling system that can reduce the temperature in a semiclosed compartment by approximately 10 °C in 25 minutes. They call it the "MycoCooler." From their recent article in PNAS:
We constructed a mushroom-based air-cooling device, MycoCooler™, based on previous observations that mushrooms can cool the surrounding air via evaporative cooling. The device was made from a Styrofoam box with a 1-cm–diameter inlet aperture and a 2-cm–diameter outlet aperture. An exhaust fan was attached outside the outlet aperture to drive airflow in and out of the box. The MycoCooler™ was loaded with ~420 g of substrate-detached A. bisporus mushrooms, closed, and placed inside a larger Styrofoam box previously equilibrated inside a warm room (37.8 °C, <10% RH). The temperature inside the closed Styrofoam box decreased from 37.8 °C to 27.8 °C, 40 min after the addition of mushrooms, cooling at approximately 10 °C, at ~0.4 °C per min.
It's an interesting concept, but somehow I don't think a MycoCooler would be powerful enough to beat the heat here in Arizona. (Though in the days before AC, everyone here used evaporative coolers. But they also say that it's much hotter here than it used to be... a combination of global warming and the urban heat-island effect.)
In 1963 and 1964, Sheaffer Pen ran an ad campaign in which they made a variety of predictions about future technologies of the 21st century. The company contrasted these technologies, which must have seemed a bit pie-in-the-sky at the time, with the timeless performance of a Sheaffer pen. The surprising thing is that all their predictions have come true: instant mail delivery, checkbooks that balance themselves electronically, portable visual phones, ring tape recorders, camera sunglasses, credit card rings, electronic translators.
They don't all exist in the specific form that Sheaffer imagined (credit card rings?), but in each case the equivalent or better exists.
