Frequency Response of a Novel IR Based Pressure Sensitive Mat for Well-being Assessment

Sensor System to Determine Force and Direction for Push Handles on Patient Transport System

“…Recently, the usage of IC-based proximity sensors in combination with a flexible layer has been examined in the context of robotic skin [39]. In one work, a new pressure-sensitive mat that combines a flexible gel material with an Infrared (IR)-based emitter/detector proximity sensing device is presented [40].…”

“…The VCNL4010 proximity sensor provides a light source, which passes through the clear gel and is reflected off the user's skin applied to the gel and then sensed by the detector within the VCNL4010. The signal that is reflected will alter when the reflecting surface moves under pressure [40] allowing for forces to be measured based on the change in pressure as indicated by the reflected signal. In this experiment 6 proximity sensors were placed into the firm gel base recesses and a clear gel layer was put on the top of the sensors (Figure 3.1).…”
