Apple Watch sensors update: Aura Strap 2 for body fat measurement

The Apple Watch Series 7 has been available in stores since October 15, 2021. There are two lengths, depending on the arm circumference. If you want, you can get the smartwatch with 41 millimeters for 415 euros. A version with 45 millimeters is also available for an extra charge. In addition to the standard bracelet made of plastic, there are also bracelets made of metal, for example. As is usual with smartwatches, the smart watch houses a number of sensors, for example for heart rate measurement. The company Aura now offers with the Bracelet Strap 2 more sensors to allow Apple Watch owners to measure more data.

Readings from the Aura Strap 2 are said to be 95 percent accurate

Roughly where a clasp normally sits, Aura has attached 2 additional sensors to the Strap 2. With these sensors, wearers can determine the proportion of body fat, muscle mass and body water. To do this, the hand without an Apple Watch must be in contact with the sensors in the bracelet for almost 30 seconds. The bracelet then transmits the data to the watch via Bluetooth 4.2. According to the manufacturer, around 95 percent of the accuracy should correspond to that of professional devices such as the Dexa-Scan.

All determined data can be displayed directly on the Apple Watch either in the Aura app or in the Apple Healthkit for further analysis. According to Aura, the Strap 2 will soon be available in the US for around $150. It is not yet known whether the bracelet will also be available in Europe. The new Apple Watch Series 8 is expected for autumn, which could also have new sensors, according to the rumor mill. Maybe the upcoming Series 8 can measure body temperature. The current Samsung Galaxy Watch 4 can already measure blood pressure and costs just under 400 euros, but is currently available from Amazon for only 274 euros. In order to be able to measure blood pressure, the Samsung smartwatch must be calibrated monthly. However, many sensors in smartwatches are currently inaccurate and provide an estimate rather than a medically correct measurement. Intensive research is being carried out into being able to measure blood pressure and blood sugar as precisely as possible, but according to experts, it will probably be several years before the time has come and medically certified smartwatches can be bought.
