Wearable Electronics – Solutions and Applications

  • Industrial: Wearable devices are set to play a major role in an industrial environment, Head mounted computers and Intelligent Headsets that work as an accessory to Smartphone enables technicians and floor managers with greater efficiency, by providing hands-free operation along with instructions, maintenance schedules and inventory information in real-time. Wearables are thus becoming a key enabler in Industrial Floors, large Warehouses, Repair & Maintenance sectors saving time and millions of dollars for the Manufacturers. Such wearable devices play vital role in real-time information capture and gateway of information to the operator in the Industrial Internet-of-Things.
  • Medical, Health and Fitness: Devices like Health Bands that come in the form of wristbands are one of the most sought-after smart gadgets for athletes and fitness conscious people, which help them track their heart rate, calories burnt during a work-out session, distance covered, etc. These devices are paired with user’s smartphone over Bluetooth to provide various health, fitness related updates to the user. Smart jewelleries are another concept which is gaining popularity now a days. Smart bandages are some of the also being used in hospitals to take better care of patients. Wearable Smart Glasses could become a quick enabler in the Medical industry, by assisting the practitioner to quickly access the complete history of a patient, previous medications, etc. and assisting during the surgery by enabling access to instruction videos and video calls to experts for real-time assistance.
  • Infotainment: Wearable electronics is extensively used in gaming and entertainment industry. This includes interactive augmented reality (AR) and virtual reality (VR) headsets, smart joysticks, smart goggles, etc.

Key Components of a Wearable Device:

MCUs and sensors [IMUs, Accelerometer, Gyroscope, Magnetometer, Barometric pressure, Ambient temperature, Heart rate monitor, Oximetry, Skin conductance, temperature, GPS] form the basic hardware of a typical wearable device. Depending on the functionalities and features to be realised on the device, developers may include displays, pedometers, keypads, etc.

The key Design considerations while designing a wearable device include:

  • Small Form Factor Hardware
  • Battery and Power Management
  • Thermal Management
  • Interfaces and Connectivity
  • Video Streaming
  • Multi-sensor integration
  • Size, Weight and Ergonomics
  • Library/Algorithm Integration
  • Wearable Electronics Application Development
  • EMI/EMC Regulations

Wearable Electronics Designs and Wearable Electronics Application Development must be user-centric, aesthetically pleasing, complying with environmental regulations and easily adoptable in real life scenario where in it can solve crucial problems.

Challenges and Risks

  • Design: Packaging massive set of functionalities and features into these advanced devices require a lot of design thinking. User’s convenience and comfort is critical and this demands for high performance/features, longer operating time while ensuring low weight, compact size, thermally safe. It can be challenging for product engineers to design a device that is universally compatible and suitable for different body types. There is lack of a common standard.
  • Privacy & Security: Securing the personal data of the user is one key aspect. These devices collect real-time data on health, user’s behavioral patterns, his preferences, etc. which needs to be secured against any kind of cyber threats.
  • Health Risks: Wearable electronics technology poses health risks and hazards to certain extend due to constant radiation exposure. It is important to keep SAR (Specific Absorption Rate) in these devices to the lowest. At the same time, it is also essential that wearable electronic devices pass all mandatory safety, environmental standards.

Wearable Electronics design companies have invested considerable amount of time and effort in the R&D of futuristic wearable devices to understand the functional, technological and business needs of the modern-day devices. The ever-evolving embedded technologies have been successful in developing Small form factor, miniature, extended battery life, rugged and ergonomic, that are a key aspect of wearable designs. Wearable Electronics Application Development along with IoT and AI is set to transform the current environment. The potential physical harm can be prevented through definition of standard, precautionary design and though testing measures.
