Assistive technology aims at easing connectivity and communication for individuals with sensory, physical or cognitive difficulties, impairments and disabilities to fully participate in society.Technological developments in electronics over the past years have made it possible to integrate many of the key features required for medical and assistive technology into mainstream products making these concepts a reality. Internet of Things in healthcare is making it easier to record and store information, while at the same time making it quicker and more effortless to access it. IoT will extend the connectivity and transmission of health data from the patient to the physician on a regular basis, or immediately and continuously in an emergency. The Medical IoT will make medicine participatory, personalized, predictive and preventive. IoT also has the potential to aid as an enabler of assistive technologies by increasing accessibility support and services for people with disabilities in domains such as health care, education, independent and assisted living, mobility and navigation in public spaces among others.

Mistral has the requisite skill sets in designing and developing electronics devices connected to the Internet of Things for medical electronics and electronics assistive technology products.
