Smartwatch that can detect electrocution?
<< < (4/6) > >>
VK3DRB:
Read the fine print. Apple watch does not have a lifetime warranty. So when you get electrocuted, the warranty is null and void. And so are you.

Seriously though, many smart watches send heartbeat data to the cloud. You could have a system where if you are scheduled to work in a dangerous location and there is no heartbeat, call emergency or set off an alarm.

Decades ago, I worked on IBM mainframes. Rule #1: No watches or jewellery. From then on, I wear neither even to this day, even plastic ones through habit. Metallic watches/watchbands and electronics don't mix.

Side note: I owe my life to my Apple Watch. Out of the blue, and without any physical symptoms, it detected some afib events over one weekend last December (2022). I thought it a fluke at first and didn't pay much attention to it, as it stopped after a couple of days and again I felt no symptoms. However it nagged at me so a few days later I made an appointment with my doctor to check it out. An EKG showed no afib by then, but kudos to my doctor -- he ordered a 30-day heart monitor which detected a few minor rhythm anomalies, so he ordered a nuclear stress test in early February. The imaging showed reduced blood flow, signs of possible blockage, leading to a heart cath procedure in late February. That's where they discovered a 90% blockage of my LAD and another artery, and 100% blockage of a smaller vessel. A "widowmaker" in the making. Two weeks later, on 3/14/2023, I had a double-bypass operation.

I was literally a walking time bomb.

All discovered due to an apparently benign warning triggered by my Apple Watch. Having no physical symptoms, and getting regular physicals and checkups that showed no signs, this would have otherwise gone undetected until a potentially fatal event occurred.

I wrote Tim Cook an email (his address is publicized and he had been reported to read customer emails) relaying the story, and in fact received a personal reply from him.

Great story, thanks. Glad you are OK. Yes, we get little notice. I had at least 98% blockage in the main heart artery and unbeknown to me I was near death when the local hospital had me left in the waiting room for seven hours, so I just walked out struggling and drove myself home at 3 am in the morning as the heart was shutting down due to no blood supply. I made it back to the hospital after I knew I was in strife, and raised my voice at the triage nurse in no uncertain terms to bloody help me. The cardiologist told me a few times later to get a lotto ticket because I should have died before I even got to hospital, and that I was the luckiest patient he had seen in a long time. They even used my case for training doctors. A later investigation said it was a systemic failure of the hospital to look at me within 20 minutes of arriving. Anyway, I got a stent and 100% OK now. Maybe an Apple Watch could have alerted to a problem a lot earlier.

Seems to be named "man down" alarm or system.
TERRA Operative:
No jewellery while working on electrical equipment and no working alone on low voltage or higher.

That's the rules an electrician or technician lives by to stay alive.
eutectique:
If you want to know a specific brand, Rombit in Antwerpen makes wearable devices for lone workers. They have a representative in the US.
