Human gait can be detected by plantar pressure. Previous wireless portable systems were not able to collect and analyze the plantar pressure from both feet simultaneously. In this study, the multi-connection capability of CC2650 Bluetooth low energy (BLE) chip from Texas Instruments was utilized to construct the pressure sensor insoles system. A smart phone application was implemented to receive,...
This paper portrays the comparison of inability of human limb in subjective way. Data is obtained for both the affected and unaffected leg of three hemiplegic patients. Foot plantar weight may be characterized as the weight field made by the middle of the foot and surface throughout ordinary exercises which depicts the disability of the man. A foot weight cushion is used to get constant foot weight...
This paper aims at development of low cost dynamic foot pressure scanner. To estimate the peak pressure points on the foot sole, a study was conducted on a healthy male group. In all, 8 subjects were placed for observation on EMED (from Novel Inc.) foot mat system at different clinics. The data, thus recorded, was analyzed using Novel-Win-Mask software and it is concluded that, on a single pressure...
In this paper we describe a wireless wearable system to monitor gait, based on a customized pair of commercial insoles able to collect ground reaction forces by use of 24 embedded cells for each foot. Each insole was combined with a small form factor, low-power Inertial Measurement Unit (IMU) and enabled to communicate via Bluetooth with a base station. We present here the characterization of the...
The measurement of interface pressure between the foot and shoe is important in gait analysis and other health diagnosis. Abnormal pressure may indicate instability in gait, risks of ulceration development especially in diabetic foot as well as have many other biomedical diagnostic applications. However, the currently available foot pressure sensors show a number of weaknesses that limit their performance...
