Wearable Device Development Testing

The wearable device market rapidly growing. Consumers are adopting wearable devices in increasing numbers, quickly, and the trend shows no signs of slowing down. As people wear these wearables for a longer duration, developers face the challenges of reliability, compatibility, and battery life. These challenges are compounded by the increased complexities of wearable devices. The growing complexity of these devices requires that developers test their devices across a wide variety of devices, operating systems, and environments.

When a product reaches the marketplace, it is tested against several specifications defined by the factory. But what happens if the products change over time? If this is the case, the manufacturer must retest the products to make sure they are still in compliance with the original specifications.

Testing Procedures

Wearable device development is seeing a boom these days. Devices that use Bluetooth and Wi-Fi connection to your smartphone, allowing sensors to collect information about a user’s walk, steps, heart rate, sleep, and more. Wearables can be used for tracking to stay motivated (a Fitbit, Apple Watch, or Garmin), or for monitoring health (such as a FitBit Flex or Garmin Vivofit). Wearables can also take the form of an activity tracker, such as a Nike FuelBand or a Jawbone UP24.

Wearable device development requires different testing procedures than another software testing, especially for software used in wearable devices. The first consideration for testing in wearable devices is battery usage. Battery life is the most significant consideration for wearable devices. The testing procedures will also include battery usage, battery drainage rate, battery charge level, battery discharge rate, battery charging time, battery temperature, battery performance, and battery capacity.

Wearable device developers can save money and hassle by collaborating with an outsourced testing lab that understands the specific needs of their technology. For example, quality testing can encompass a variety of types of testing, like burn-in testing, drop testing, vibration testing, ESD testing, temperature testing, and others. The latter, temperature testing, is often the first test performed on any wearable device design. When handling temperature testing, wearables should be tested in ambient conditions, and temperatures ranging from -40 to +90 degrees Celsius.

Wearable Medical Device Development Testing

Wearable medical devices are proving to be more and more popular. Wearable devices take many forms from watches to glasses, to footwear, to headbands and more. They can be used for monitoring health and exercise or help manage medical conditions like sleep apnea.

While wearable medical devices are quickly gaining traction among consumers, these devices face many challenges that traditional medical devices don’t. In fact, the FDA is currently developing guidance on wearable medical devices.
