Smart wearables are intelligent miniature systems that are embedded in everyday objects or worn on or even in the body. The integrated miniature systems mutate these objects into smart clothing, smart shoes, smart bracelets, smart watches, smart glasses or wearable cameras.
Smart wearables are wirelessly operated systems that display their data directly or transmit it via wireless protocols to smartphones, tablet PCs or personal computers. They consist of several functional units such as the battery or coin cell, the power supply circuit, the sensors, a power-saving ASIC or processor, and the radio unit with antenna. The space-saving spray-on antennas are ideal for this purpose. The smart wearables can also be connected to the Internet.
One thing distinguishes all smart wearables: They have extremely low power consumption and transmit their data using energy-saving radio protocols such as Bluetooth Low Energy( BLE) or ANT+. This allows smart wearables to run on small button cells or tiny lithium polymer batteries, or even micro energy harvesting. Energy-saving techniques include reducing the operating voltage and lowering the oscillator frequency in standby.
Smart wearables contain various sensors via which, in the case of fitness wristbands or smartwatches, training performance, body temperature, blood pressure or other medical values can be determined. Geographical data of the user or weather data can also be shown on the display.
Other examples from the healthcare sector include smart contact lenses that measure blood glucose levels via the tear fluid, smart tattoos that measure skin hydration, body temperature and muscle electrical impulses, and smart plasters that are applied to the human skin and measure vital signs.
Smart wearables are lifestyle products for sports and leisure activities, but also for healthcare, e-commerce and automotive technology.
