The medical devices industry continues to be a hotbed of innovation, with activity driven by increased need for homecare, preventative treatments, early diagnosis, reducing patient recovery times and improving outcomes, as well as a growing importance in technologies such as machine learning, augmented reality, 5G and digitalisation. In the last three years alone, there have been over 450,000 patents filed and granted in the medical devices industry, according to GlobalData’s report on Robotics in Medical Devices: Robotic exoskeleton.

However, not all innovations are equal and nor do they follow a constant upward trend. Instead, their evolution takes the form of an S-shaped curve that reflects their typical lifecycle from early emergence to accelerating adoption, before finally stabilising and reaching maturity.

Identifying where a particular innovation is on this journey, especially those that are in the emerging and accelerating stages, is essential for understanding their current level of adoption and the likely future trajectory and impact they will have.

150+ innovations will shape the medical devices industry

According to GlobalData’s Technology Foresights, which plots the S-curve for the medical devices industry using innovation intensity models built on over 550,000 patents, there are 150+ innovation areas that will shape the future of the industry.

Within the emerging innovation stage, HUDs for surgical navigation, robotic biopsy endoscope, and camera-guided surgical robots are disruptive technologies that are in the early stages of application and should be tracked closely. Robotic exoskeleton, surgical robots and robotic catheters are some of the accelerating innovation areas, where adoption has been steadily increasing. Among maturing innovation areas are robotic lower limb rehabilitation, and microfluidic lab-on-a-chip, which are now well established in the industry. 

Innovation S-curve for robotics in the medical devices industry

Robotic exoskeleton is a key innovation area in robotics

Exoskeletons are wearable machines that enhance human performance by allowing limb movement with increased strength and endurance. Exoskeletons can also be designed for lumbar support to help with lifting heavy objects. The main use cases are in medicine, the military, manufacturing, and logistics.

GlobalData’s analysis also uncovers the companies at the forefront of each innovation area and assesses the potential reach and impact of their patenting activity across different applications and geographies.  According to GlobalData, there are 30+ companies, spanning technology vendors, established medical devices companies, and up-and-coming start-ups engaged in the development and application of robotic exoskeleton.

Key players in robotic exoskeleton – a disruptive innovation in the medical devices industry

‘Application diversity’ measures the number of different applications identified for each relevant patent and broadly splits companies into either ‘niche’ or ‘diversified’ innovators.

‘Geographic reach’ refers to the number of different countries each relevant patent is registered in and reflects the breadth of geographic application intended, ranging from ‘global’ to ‘local’.

Samsung Group is one of the leading patent filers in the field of robotic exoskeleton. Some other key patent filers in the field include Otto Bock, Cyberdyne, Ekso Bionics, and Honda Motor.

In terms of application diversity, Superflex leads the pack, followed by HapTX and Toyota Motor. By means of geographic reach, ExoAtlet Global holds the top position, followed by BioServo Technologies and SRI International in the second and third spots, respectively.

Owing to the increased need to support patients lacking proper coordination in movement due to an injury or disease, more advances are being made in this field. Advances in brain-machine connectivity will impact the evolution of exoskeletons. In near future, exoskeletons are expected to support patients with incurable health conditions such as amyotrophic lateral sclerosis. Future research should focus on developing low-weight and affordable devices.
