Whether it’s Fitbits, Basis Bands, Fitbugs or Flex Bands, wearable wellness devices continue to flood the market and will remain the ‘next big thing’ for quite some time to come, gauging from the buzz at the Consumer Electronic Show 2015. It is estimated that from $4 billion, the industry will grow to an $8 billion moneymaking enterprise by 2018.

Wearable device manufacturers are always on the lookout for new trends and improving the quantity and type of data collection to keep users hooked and motivated.

Engadget’s Editor-in-Chief Michael Gorman says that in the next couple of years, the focus will be on two areas — sensor-laden clothing for fitness buffs and headband wearables for consumers who lean more towards meditation and stress relief aids.

A new entrant in sensor-equipped clothing is the brand Athos, which is launching a gym shirt that includes 14 muscle movement sensors, two heart rate and two breathing sensors. The goal is to train more effectively, avoiding pain and injury. Syncing with your mobile device through Bluetooth the sensor will allow you to view which muscles are working, to see if you’re relying too much on helper muscles or leaning on one side of your body.

Sensora’s Smart Socks have features that help you keep track of your running form, activity level, step count and distance covered. For $200, you can get two pairs of socks and an anklet connector.

Working with an app called Calm over Bluetooth, a Muse headband costing $299 is coming up on the market. It provides you real-time feedback to get into a reflective mind state and to block out distractions, developing greater focus.

If you’re looking for something a little friendlier on the wallet, NeuroSky’s $79 Mindwave headset, which works with various third-party apps, is also a good choice. It allows you to play games, control devices and meditate in more efficient ways. It reportedly helps to ease anxiety and reduce symptoms of ADHD. The company claims it can provide relief in brain-related stomach disorders too, like irritable bowel syndrome, which has its roots in stress.
