Samsung patent reveals a Note device with breathalyzer stylus

Styluses have been around for quite a while, but they did not evolve much. However, a patent by Samsung that recently surfaced online shows a possible future for this accessory - multiple functions. In this case, it revolves around a 3-in-1 stylus that can also act as an external microphone and a breathalyzer.

The patent mentioned above shows a Note handset featuring a stylus that has a moving body portion with a gas sensor on one end. This part also acts as a microphone. According to the patent filing, "The gas sensor portion may include a sensor module that analyzes the exhalation, a short-range transceiver unit that transmits data measured by the sensor module to the device main body, a sensor battery that supplies an electric power to the sensor module and the short-range transceiver unit."

The patent was originally filed in June last year and was published by the U.S. Patent and Trademark Office last month. If it makes it to the market, we expect it to be available for older devices as well and to offer various other functions as well.
