content: if you could add anything to a watch. electronics what would you have. it must fit inside a watch case or the watch band.the battery must last minimum of 24hrs on a charge so that limits laser pointer & LED flashlight power. but the maximum battery life can be yrs.I made a list-the watch case can be a tool like a bottle or stubby opener.alcohol breath tester.digital spy cameraremote control door opener car or house.CB radio - dick tracy watch low power UHFdog whistle - ultrasonic piezoelectric callerbody temperature sensorpulse rate sensorwatch linked to smartphonepedometer G sensorGPSdigital compasswaterprooftell the time.stopwatch

content: conductive underside with a few electrodes, allowing you to map sensor data to them,You get a bit sweaty so you have a natural electrolyte,So imagine having compass angle mapped to a pulse width with low enough amplitude that your just aware of it,you get used to it, and suddenly you know which way to go without using any kind of display,

content: Replace the battery with a nuclear power source to run all of the above.Betavoltaic cells give 24W per kilo, so you'll have plenty of power to run all the perks smartwatches are advertised for, without any recharging necessary.

content: Quote from: JPortici on November 20, 2016, 08:44:12 amYep, proper breath analysis devices are expensive (and don't fit inside a small device). The proper gear like what law enforcement and hospitals use are based on fuel cells. But even then, those portable devices (which are still the size of an old 1990's brick phone) only give a rough indication of BAC and a secondary test is required on an even more expensive (and larger) machine. Both types of devices also need regular calibration.Those small pocket BAC testers are a waste of money. They probably do OK at detecting the presence of alcohol in the breath but I wouldn't trust any reading as far as I could throw them.

content: That laser would be cool on a watch! It doesn't even have to be a steel-cutting laser, but something around 300mW would be fun, just to pop baloons in parties.I've been waiting for a long time for smartwatches (or just smart wristband) with several vital signs functions in a single device:- glucose- blood pressure- oximeter- body temperature- heart frequency, etc and so on.A few environmental measurements:- air humidity level- air toxicity levels, but just for a few common gases, such as propane, butane, carbon monoxideOther must haves:- GPS- BLE 4.0- vibrating alert- Uses Android OS, so I can develop apps for itWhat I have in mind is something that can be worn by elders, so that relatives or caretakers can monitor their health and environment remotely. There wasone device on IGGlast year that claimed to have all of these features, but apparently it was a scam worse than Batteroo.
