AI Technical Summary

Technical Problem

The pressure sensors on existing smart mattresses are sparsely distributed, making it impossible to accurately capture subtle changes in posture. Furthermore, the rigid sensors can cause a foreign object sensation, affecting the user experience.

Method used

By employing a high-density array of flexible tactile sensors, combined with piezoelectric materials and a signal acquisition unit, the flexible tactile sensors capture pressure changes inside the mattress, enabling precise monitoring of sleeping posture and physiological signals.

Benefits of technology

It enables precise monitoring of sleeping posture and physiological signals, eliminates the foreign body sensation of traditional sensors, provides high-density pressure point detection, and supports sleep quality assessment.

Abstract

This invention relates to a high-density sensory mattress, comprising a mattress body, flexible tactile sensors, and a circuit. The mattress body has recessed grooves in which multiple flexible tactile sensors are disposed. The flexible tactile sensors are characterized by comprising an upper insulating layer, an upper electrode layer, a middle pressure-sensitive layer, a lower electrode layer, and a lower insulating layer. The middle pressure-sensitive layer is located between the upper and lower electrode layers. Both the upper and lower electrode layers consist of several evenly spaced linear electrodes. The circuit comprises a signal acquisition unit and a host computer. The signal acquisition unit uploads the acquired signals to the host computer via Bluetooth communication. This high-density sensory mattress can not only analyze the user's sleeping posture but also obtain the user's breathing and heartbeat signals through changes in pressure values, providing data support for assessing the user's sleep quality.
