EXO BRACE (2014)
Development of a functional tissue-safety system for integration with powered exoskeletons
Assistive and rehabilitative powered exoskeletons for spinal cord injury (SCI) and stroke Patients had recently reached the clinic. Challenges still existed in adjustment and fitting, with most systems depending on personnel experience for appropriate individual fastening.
Paraplegia and tetraplegia patients using these devices have impaired sensation and cannot signal if straps are causing excessive pressure and blood-flow restrictions which can lead to skin ulcers, necrotic tissue and infections.
This system monitors pressure exerted by physical human-machine interfaces and provides data about levels of skin/body pressure in fastening straps.
Functional safety prototype developed and Tested with Spinal Cord Injury (SCI) patient on REX Exoskeleton TRL = 7 (Houston, TX). validated for product integration.
included in exoskeleton patents for méxico currently in process of entering latin american market.

components: sensing arrays, signal processing hardware with wireless transmission, and an interactive GUI.
Validation: REX (New Zealand) lower-body powered exoskeleton carrying the full weight of users was used.
