Method of software redundancy for home healthcare system based on ISO 26262

ISO 26262 is an international functional safety standard for automotive systems. In contrast to the automotive field, where the configuration of redundant devices for safety is essential, the home healthcare field does not enforce redundancy. Thus, home healthcare devices that require high reliability, such as artificial hearts, can be susceptible to potential dangers. We therefore propose a safety redundancy method for home healthcare devices that is based on ISO 26262.
