Low cost piezoresistive pressure sensor matrix for pressure ulcer prevention and management

Combating Pressure Ulcer (PU) prevalence have proven to be time and cost-intensive. Higher risk of morbidity is seen from slight negligence with immobilized subjects. Best PU prevention mostly revolves around constant pressure unloading once above 32mmHg which is detrimental on the blood capillarie...
