Multimodal Sensor System for Pressure Ulcer Wound Assessment and Care

Hyperspectral imaging in wound care: A systematic review

“…In most cases (n = 19) the multi‐patient studies were reported 1,2,5,7,54‐68 . However, in some cases (n = 12), the case studies were reported 8,50,69‐78 …”

“…Liu et al 77 developed a 3D topography multiview/HSI integrated system. Chang et al 72 proposed a multimodal system (3D wound size measurements, HSI, thermo, and chemical vapour sensing analysis) for pressure injury assessment.…”

“…Chang et al 72 used a multimodal system (3D wound size measurements, HSI, thermo, and chemical vapour sensing analysis) to assess the probability of healing of pressure injuries.…”

“…Chang et al 72 validated their multimodal system on 23 patients with pressure injuries. They found that peri‐wound temperature difference correlates most strongly with the healing trend with a threshold of −2°C.…”

A deep learning approach for pressure ulcer prevention using wearable computing

“…An example comes from [22], where the authors developed a wearables wireless patches system by placing them directly in risk areas on the skin of the subjects by monitoring contact pressure, temperature, humidity and movement and sending the values to a base location. Authors in [6] developed a multimodal sensor system for the evaluation and treatment of PUs that can provide spectral, thermal and chemical analysis, the real-time vision of injury size and prediction of wound healing in support of hospitals, clinics and home environments. Authors in [20] propose a technique for the prevention of PUs that helps patients effortlessly and independently, which comes from a system that provides electrical stimulation to the pressurized points of the gluteal muscles through a smartphone application connected wireless to the head and regulates the electrotherapy parameters.…”
