“…The approach using intermediate flexPCB was considered, in general, moderately adequate for bedridden patients, particularly due to the flexPCB's rigidity and embroidery roughness. Different studies associate the development of new technologies to monitor changes in skin (pressure and temperature) to a more effective prevention of pressure ulcers, compared to diagnosis only by observation [46][47][48], in particular because wearables can trigger interventions and inform care delivery [49].…”

Environmental factors, such as pressure and temperature, are known to contribute to the formation of ulcers that seriously affect bedridden individuals. Researchers have proposed several technologies to achieve the long-term monitoring of those parameters, usually relying on sensing mats, which poses difficulties in correlating the measurements with specific parts of the body. In this work, we aim to develop microsensors to be integrated into patient clothing. They should be highly flexible, thin with a small footprint, and can be achieved by taking advantage of the microfabrication on polyimide (PI) thin-film substrates (total device thicknesses below 30 µm). Both resistive and capacitance transduction mechanisms were explored, targeting operation ranges of 1 to 40 kPa and 24 to 42 °C. The sensors were integrated into textiles using silicone elastomers and electrical connections based on conductive silver yarn. The experimental characterization showed a nominal capacitance of 21 pF, a sensitivity of −8.44 fF/kPa for the pressure sensors, and a 0.0021 Ω/Ω°C sensitivity of the temperature sensor (with resistance of 29 kΩ at 22 °C). The proposed approach can potentially be implemented not only in wearable devices but also in many other applications for health monitoring or human–machine interfaces.

“…Light at 660nm wavelength has therapeutic effects on pressure ulcers [2]. In previous research, a pressure ulcer management device was developed that diagnoses by measuring the impedance of the skin and treats pressure ulcers early with 660nm light therapy [3,4]. This paper proposes a machine learning algorithm for the diagnosis and treatment of pressure ulcers, based on this research, utilizing impedance measurements to adjust the output of light needed for treatment [5,6].…”

Pressure ulcers are a significant concern in intensive and long-term care settings, posing a substantial financial burden with costs reaching approximately $167,000 for a four-stage ulcer. These ulcers progress from stage 1 to stage 4, with stages 3 and 4 marking a transition to irreversible inflammation, underscoring the importance of early diagnosis and treatment. The incidence and prevalence of pressure ulcers vary internationally, with reports indicating an average of 22-44% in intensive care units across US hospitals. Given their substantial prevalence and the financial and human costs involved, early treatment and prevention are paramount healthcare objectives. In response, we introduce an algorithm for a pressure ulcer treatment device, leveraging biophotonics sensor technology for impedance measurement and light irradiation, as developed in prior research. This algorithm generates a wound map from impedance data, facilitating tailored light output adjustments for each impedance pin based on the map. Validation through 10-Fold Cross Validation yielded an accuracy rate of 91% for the algorithm. Furthermore, we posit that ongoing advancements in mobile healthcare and data analytics will significantly enhance the efficacy of pressure ulcer treatment devices, streamlining management processes.
