Hiyd has launched a Kickstarter campaign for the second-generation HIYD, a small waterproof sensor that attaches under most watches to track heart rate, blood oxygen, skin temperature and movement. The company claims the device is 2.7mm thick, weighs about 2.9g and has an IP68 rating, with up to four days of battery life per charge. An optional Battery Band accessory extends runtime to 20 days. The early bird price is $199, with no app subscription fees promised for backers and delivery expected in May, though fulfillment is not guaranteed.
