Abstract: A sensor grid is provided which is able to provide signals of the magnitude and location on the grid of applied pressure. In the prime application of gait analysis, the sensor in the sole of a shoe provides over time a signal indicative of the magnitude and movement of the centre of pressure. This may be presented as a visual signal showing the location of the centre of pressure on the outline of the sole with pressure values coded in colour. Alternatively the location may be represented as pitch of an audio signal and the magnitude by sound volume. Such a signal can be used to provide feedback to a patient to correct their gait by modifying their gait to produce a desirable signal. The analysis software uses an algorithm to identify the location, speed and distribution of the centre of pressure (COP) and additionally to assess the fractal dimension of the COP. Other attributes such as location of hotspots and pressure impulses can be used to augment the biofeedback signals. The sensor system may be used in other sensing applications such as measuring impacts in sports or pressure points in patients confined to sitting or prone positions.

Abstract translation: 提供传感器网格，其能够提供施加压力网格上的幅度和位置的信号。 在步态分析的主要应用中，鞋底中的传感器随时间提供指示压力中心的大小和运动的信号。 这可以作为视觉信号来表示，其中压力值以彩色编码，示出了鞋底轮廓上的压力中心的位置。 或者，位置可以表示为音频信号的音高和音量的大小。 这样的信号可以用于通过修改其步态以产生期望的信号来向患者提供反馈以校正其步态。 分析软件使用算法来识别压力中心（COP）的位置，速度和分布，另外评估COP的分形维数。 可以使用诸如热点位置和压力​​脉冲的其他属性来增加生物反馈信号。 传感器系统可用于其他感测应用，例如测量受限于坐姿或俯卧位的患者的运动或压力点的影响。
