Emerging $5.5B Market for Sensors in Wearable Tech

Sensors are an essential component of most Internet of Things (IoT) use-case scenarios. Sensors also enable the key applications in wearable devices. This is why made-for-wearable sensors are being developed around the world, and the market is already primed for significant growth.

According to the latest worldwide market study by IDTechEx Research, made-for-wearable sensors will represent 42 percent of all sensors in wearable devices in 2026 -- that's up from just 7 percent in 2015.

There will be a $5.5 billion market for sensors used in wearable technology applications by 2025. However, several key challenges must be overcome before these sensor technologies can realize their full potential.

Wearable sensor systems will help to drive market development. The textile and electronics industry has started to merge together around e-textiles. High-value sport and fitness applications are the current focus. Vertical industry apps will also include healthcare, home textiles, and industrial spaces in the next 2-5 years.


The IDTechEx study findings demonstrate that these sensor types will proliferate in the coming decade. As the number of wearable devices increase, deployed sensors used to detect motion, force and pressure will gain momentum, growing at a 40 percent CAGR.

This broad technology landscape is a challenge for product designers. With many different materials come varied requirements for connector types, electrical specifications and data algorithms.

In 2015, according to the IDTechEx assessment, half of all wearable sensors were based on MEMS technologies. Moreover, inertial measurement units (IMUs) are found in every smartwatch and fitness tracker.

However, the challenge is in turning raw data from these devices into useful, or actionable information. The solution is Sensor Fusion --it's the process of combining outputs from multiple sensors to gain more insight.

This in turn can be used to count steps and differentiate between activity types. It is here that MEMS IMUs see more use cases. For example, they are used alongside optical sensors to manage motion artifacts experienced in optical heart rate monitoring.

How a Digital-First CEO Leads Transformation

Some leaders reject the notion that "wait and see" is the best response to disruptive change. Savvy senior executives are already driving digital business transformation throughout their organization in an effort to gain a bold strategic advantage. According to the latest market study by International Data Corp (IDC), Digital-First CEOs plan to drive at least half of their income from digital business products, services, and experiences by 2027 -- that's ahead of the market average of 39 percent. Driven by their response to the COVID-19 pandemic, these business leaders have changed how they think about the relationship between business and technology, and how they approach the next digital transformation era -- from scaling digital technology to guiding a viable digital business. Digital Business Market Development IDC defines digital business as value creation based on technology, which entails: 1) Automated customer-facing processes and internal operations; 2) Provision

Digital Solutions for Industrial & Manufacturing Firms

Executive leaders of fast-moving consumer goods (FMCG) are seeking guidance on how to apply new business technology in their manufacturing operations. CIOs and CTOs are tasked with gaining insight into the best solutions for digital transformation. ABI Research evaluated the impact politics, regulation, the economy, supply chain, ESG, and technology are having on FMCG, pharma, producers of steel, chemicals, pulp and paper -- as well as the mining and oil & gas sectors. Digital Transformation Market Development "Our assessment found that the FMCG sector is under pressure from all sides," says Michael Larner, industrial & manufacturing research director at ABI Research . Securing raw materials is challenging considering lockdowns in China and limited grain supplies from Ukraine. Supply shocks are raising input costs, and operating costs are rising with higher energy costs coupled with the pressure to pay higher wages and work sustainably. "We all hoped that with th

Retail Transformation Gains New Momentum

Forward-thinking retailers now have a bright future. In contrast, those that failed to enhance their business model via digital transformation have struggled, declined, and their assets were eventually liquidated. The key difference between these two business outcomes is applied strategic foresight. Even as the world continues to emerge from a global pandemic, retail is growing at levels not seen in the last two decades. Retail sales grew by 7 percent in 2020 and by over 14 percent in 2021, which is in stark contrast to the 3.7 percent annual growth between 2010 and 2019. The increased demand for retail has put a strain on supply chains and retail operations worldwide. As a result, retailers and stakeholders are turning to automation solutions such as mobile robotics for operational ease. Retail Transformation Market Development According to the latest market study by ABI Research, worldwide commercial robot revenue in retail stores will have a Compounded Annual Growth Rate (CAGR) of o
