Pressure ulcers and skin damage are common complications among patients with limited mobility, particularly those confined to bed for prolonged periods. This project introduces an automated system aimed at enhancing patient comfort and preventing skin degradation by monitoring sweat levels and dynamically adjusting the bed surface to maintain optimal conditions. The system integrates a sweat sensor, temperature sensor, and pressure sensors with a PIC16F877A microcontroller, which continuously collects and analyzes data to control a motor driver responsible for inflating or deflating bed segments. This process promotes effective pressure redistribution and air circulation, significantly reducing the risk of pressure ulcers. The microcontroller performs real-time data processing locally, enabling immediate and adaptive adjustments that enhance system responsiveness and maintain user privacy. An LCD display provides live feedback on the patient's sweat condition, aiding caregivers in timely interventions. By combining sweat monitoring, intelligent pressure modulation, and active air management, the system offers a proactive alternative to traditional care methods. Conventional approaches, such as repositioning patients every two hours or using static pressure-relief mattresses, often fall short due to limited caregiver availability and lack of consistent monitoring. This solution addresses those challenges by delivering an efficient, technology-driven method to support ulcer prevention and improve overall patient care outcomes.
