US 12,631,506 B2 · Printed electronic sensing device and applications thereof

Abstract

A printed electronic sensing device is provided for use with insole devices, gripping devices and other similar articles. The printed electronic sensing device is configured to measure force applied thereon and at least one of proximity and friction. In one form, the electronic sensing device includes a flexible, substantially planar substrate having a pair of opposed surfaces, including a first surface and an opposed second surface, at least one force sensing resistor (FSR) additively printed on the first surface, said FSR configured to sense pressure applied to the device, and at least one capacitive sensor additively printed on the second surface, said at least one capacitive sensor configured to sense at least one of sliding of an object across the second surface and proximity to the object relative to the second surface of the device.

Dependent claims

A printed electronic sensing device for measuring friction of an object relative to the device, said device comprising:

a flexible, substantially planar substrate formed from at least two layers, including an outer layer and an inner layer;
at least one force sensing resistor (FSR) additively printed between the at least two layers of the substrate, said FSR configured to sense pressure of the object relative to the device;
and
at least one capacitive sensor additively printed on an outer surface of at least one of the inner layer and the outer layer of the substrate, said at least one capacitive sensor configured to sense sliding of the object relative to the outer surface of the device,
wherein the at least one capacitive sensor is at least partially overlaid atop the at least one FSR so as to enable the device to measure the friction of the object relative to the device at a single point.
