the science behind

heart rate & heart rate variability

A brief overview of the science behind what heart rate (HR), heart rate variability (HRV), and how our smart and sustainable sports bra is found on solid science.

Optical vs. Electrical, On Chest vs. On Wrist

Heart rate Sensors

Generally, heart rate sensors come in two broad forms: optical & electrical. Wearme uses electrical sensors that are embedded in the under bust support of the smart bra, taking multiple measurements each second from their most convenient location - right on top of the heart & end-to-end across the rib cage.

On Wrist heart rate monitors most often use a technology called Photoplethysmography which measures the blood volume controlled by the heart's pumping action, which most often uses algorithms to compensate for its inaccuracy, and mostly come embedded in your smart watch or activity trackers.

SAMPLING RATE & Accuracy

MUCH MORE ACCURATE (+/- 1 BPM)

MOST ACCURATE HEART RATE MONITOR ON MARKET

According to wikipedia, the average accuracy in the market lies somewhere around 95%.

Although the difference sounds negligible, the more accurate your heart rate data, the better you would understand your workout and better monitor your health.

The negligible inaccuracies would also become significant overtime when aggregated.

Comfort, Daily Use & Ease of Cleaning

Comfie, Sweat and rain resistanT

Intensive workouts often involve sweat as well as rain in case of out door activities. Wearme's smart & sustainable sports bra is IP67 (Ingress Protection 67) certified, which means it is fully sweat and rain resistant. It also means it could be submerged in water to up to 3 ft. (1 Meter) of water for 30 minutes.

The embedded electrodes in the inner under bust are machine washable; which makes them easy to clean.

They also are very comfortable to wear and elastic.

AND ABOVE ALL

IT IS GREEN, IT IS SUSTAINABLE

MADE FROM RECYCLED POLYESTER

89% of the bra is made from recycled fabrics made from polyester, which makes it sustainable as well as comfortable wear.

By adding 11% elastane we turned this sport bra in to a breathable, eco and skin friendly smart bra with comfortable under bust support.

We plan to make it even greener by Carbon Trading to offset the Carbon emission from transportation and delivery.

Open hardware architecture

The best and most durable components
Bluetooth 5.1 inside, safest & most versatile
Detachable design (Change the bra, use the same Control Unit)
NO VENDOR LOCK IN - Compatible with almost all workout apps

FUN FACT: HR and HRV sensors have been commercially available and in use for intensive training by athletes since 1983!

Huge area to sample heart rates from

The electrode sensors are located right above the aorta, and run end-to-end across the ribcage, widening the area for sampling your heart rate and heart rate variability, while taking measurements multiple times each second.

Calorimeter, accelerometer & Gyroscope (via Your phone/APP)

Could be used in tandem with your smart phone to measure your fat/calorie burn, distance travelled, and steps taken during your workout. It is compatible with most work out apps, such as Whaoo, Polar, Runtastic etc.
