Plantiga is a an AI-powered sensor system designed for return-to-play and on-field monitoring. Our IoT sensors can be embedded in orthotics, shoes, sock liners, or our insoles to capture individual limb biomechanics, step-by-step, and stride-by-stride. We know that injuries can be mitigated by identifying and training movement deficits, but there is a gap between what can be measured in controlled environments and what happens in the real world. Plantiga’s unobtrusive, wireless sensors enables lab-quality biomechanical assessment in any environment, so you can make better decisions and drive better outcomes.
