Matrix Industries is a company that develops innovative wearable technology products. Their flagship product is the PowerWatch, launched in September 2017. The PowerWatch is a smartwatch that is powered entirely by the user's body heat, eliminating the need for recharging. This is achieved through the use of thermoelectric technology combined with an intuitive power meter.
The PowerWatch offers several key features focused on health and fitness tracking. It includes a calorie counter that accurately measures calories burned by converting body heat into electrical energy. It also has a step counter that uses sensors to track the user's daily activity levels. The sleep tracker monitors sleep quality and ensures users maintain a set sleep/wake schedule. Additionally, the PowerWatch is water-resistant up to 50 meters, one of the highest ratings for smartwatches at the time of its launch.
The PowerWatch connects to a companion app for iOS and Android, allowing users to manage the watch's functionality and analyze their performance metrics. The app enables features like setting fitness goals, tracking calorie burn, step count, and sleep data. It also facilitates competition with friends to motivate users toward their fitness objectives.
By leveraging thermoelectric technology to harness body heat as a power source, the PowerWatch offers a unique and innovative solution, eliminating the need for regular recharging that plagues most smartwatches.

Biostrap is a company that provides scalable and customizable biosensor-based precision health monitoring solutions. Their innovative wearable devices, such as the Biostrap Kairos launched in July 2023, offer advanced autonomic nervous system analysis and quantification of the sympathetic and parasympathetic branches through wrist-worn devices. Kairos utilizes a high-sensitivity CMOS optical sensor to capture raw photoplethysmography (PPG) data, enabling accurate computation of biometrics like heart rate, heart rate variability (HRV), beat-to-beat intervals, respiratory rate, and sleep-related parameters.
Biostrap's key differentiator lies in its commitment to delivering clinically reliable nervous system analysis through detailed and transparent biometric measurements. The Spot Check feature provides real-time visualization of the underlying PPG signal, signal quality, and R-R intervals, granting untethered access to every data point captured. This configurability and data integrity attracted clients like the National Police Wellbeing Service (NPWS) in the UK for their sleep, fatigue, and recovery program.
Kairos underwent extensive testing by HRV experts and achieved impressive accuracy levels, comparable to ECG chest straps. The launch marked Biostrap's pivot from the consumer wearable market to offering configurable hardware and software solutions for enterprise and research purposes.

Caeden is a wearable technology company that develops smart bracelets focused on promoting mindfulness and reducing stress. Their flagship product, the Sona smart bracelet, combines fashion and technology by integrating an advanced heart rate sensor into a genuine leather bracelet design. Launched in May 2016, the Sona retailed for USD 200 and offered a unique "Resonance" program, consisting of various breathing exercises tailored for different moments throughout the user's day.
The Sona aimed to provide a reprieve from the fast-paced city life by enabling users to start their day with a moment of zen, find calm and focus before important meetings, and unwind after workouts through concentrated breathing exercises. Caeden's founders, Nora Levinson and David Watkins, believed that regular use of the Resonance program could help build the user's resistance to stress, addressing a significant health issue faced by many.
Differentiating itself from step-tracking devices like Fitbit and smartwatches acting as smartphone extensions, the Sona positioned itself as a luxury item powered by technology designed to improve the wearer's overall quality of life through mindfulness. With its discreet design concealing the technology, the Sona aimed to offer mindfulness without drawing attention to the wearer's use of a device for that purpose.

MyKronoz is a Swiss company that specializes in producing innovative hybrid smartwatches. Their flagship product, the ZeTime, was first launched in 2017 after a successful crowdfunding campaign on Kickstarter. The ZeTime features a unique design that combines traditional mechanical watch hands with a full-color touchscreen display, allowing it to function as both an analog watch and a smartwatch.
The watch offers activity tracking capabilities, including monitoring steps, calories burned, and sleep patterns using built-in sensors such as an accelerometer and optical heart rate monitor. It also provides smartwatch functionalities like displaying notifications, controlling music playback, and viewing incoming calls. The ZeTime's mechanical hands intelligently adjust their position to avoid obstructing the touchscreen display when interacting with the device.
One of the key advantages of the ZeTime is its impressive battery life. In watch mode, the battery can last up to 30 days on a single charge, while the smartwatch mode offers around 3-4 days of usage. The device also allows users to customize watch faces, either by selecting from pre-set options or creating their own designs using templates or personal photos.
The ZeTime received praise for its innovative concept and strong battery life. Some reviews, however, criticized its half-baked operating system, unresponsive touchscreen, and inconsistent activity tracking. Despite these drawbacks, MyKronoz's hybrid smartwatches garnered global recognition for their unique approach to wearable technology.

Ringly is a company that produces fashionable smart jewelry, primarily rings and bracelets, aimed at the female market. Their devices are designed to discreetly notify wearers of incoming calls, messages, and app notifications through vibrations and LED lights. The rings are made from materials like 14k gold, sterling silver, and semi-precious gemstones like onyx, labradorite, and moonstone.
Ringly's core product is a smart ring that connects to the user's smartphone via Bluetooth. Through the Ringly app, users can customize which notifications trigger the ring's vibrations and colored LED lights. The app supports over 100 apps like calls, texts, emails, calendar alerts, and social media platforms. The rings are water-resistant and have a battery life of 2-3 days.
While technologically simple, Ringly's rings prioritize a fashionable and discreet design over advanced features. The idea is to provide a stylish alternative to smartwatches that seamlessly blends into the user's wardrobe and lifestyle without being obtrusive. Ringly has focused on creating fashionable jewelry pieces that also offer practical notification capabilities.

Healbe Corporation is a technology company that develops wearable devices and associated software for health and wellness monitoring. The company's flagship product is the Healbe GoBe, a smart band that utilizes proprietary FLOW Technology to automatically track various body parameters. The GoBe device employs a combination of sensors, including an accelerometer, piezo pressure sensor, and impedance sensor, along with advanced algorithms to provide insights into users' overall health.
The GoBe smart band is designed to automatically measure calorie intake through the skin, eliminating the need for manual food logging. It also tracks calories burned, hydration levels, stress levels, sleep quality, heart rate, blood pressure, and physical activity. In November 2015, Healbe introduced automatic hydration level monitoring to the GoBe device, making it the first wearable to offer this feature without requiring manual input of fluid consumption.
Healbe's technology adapts to individual body characteristics, providing personalized insights and recommendations. The device monitors hydration levels continuously and alerts users when they need to drink more water. It also tracks emotional stress and helps users correlate it with their body's physical responses. The GoBe smart band measures energy expenditure throughout the day, including basal metabolism, regardless of physical activity levels.
The company's latest model, the GoBe3, incorporates additional features such as EDA-based Neuroactivity tracking and physiological stress estimation. It also offers improved sleep tracking capabilities, including detailed analysis of sleep phases and smart alarm functions designed to wake users during optimal sleep stages.
Healbe has developed a companion mobile application that synchronizes with the GoBe device in real-time, allowing users to view and analyze their data. The app provides detailed information on various health parameters and offers integration with Google Fit for a more comprehensive health data ecosystem.
