Abstract: An arrangement of an expandable substrate and a strain sensor applied onto a surface of the substrate. The strain sensor is made from an ink composition that is a mixture of a conductive silver ink and a conductive carbon ink. A ratio between the conductive silver ink and the conductive carbon ink lies in a range between 30:70 and 70:30 in on arrangement and between 40:60 and 60:40 in another. A method for forming the arrangement directly prints the strain sensor on the substrate.

Abstract: A strain gauge (10, 40, 50), a pressure sensor (20, 60), and an interventional medical catheter. The strain gauge (10, 40, 50) comprises a substrate (11) and at least two sensitive gages (1, 2) provided on the substrate (11), the at least two sensitive gages (1, 2) being arranged along two mutually perpendicular directions and sharing one ground port (3). The pressure sensor (20, 60) comprises an elastic body (21, 61) and the strain gauge (10, 40, 50) provided on the elastic body (21, 61). The interventional medical catheter comprises a catheter distal end and the pressure sensor (20, 60) provided at the catheter distal end. The present application not only saves the trace space for mounting and using the strain gauge (10, 40, 50) on the interventional medical catheter, facilitating the successful mounting and use of the strain gauge (10, 40, 50) on the interventional medical catheter, improving the adaptability of the strain gauge (10, 40, 50), but also reduces the size of the strain gauge (10, 40, 50), thereby shortening the length of the elastic body (21, 61) of the pressure sensor (20, 60) and reducing the size of the interventional medical catheter.

Abstract: A protective garment contains a projectile detection device, in addition to impact and breach resistant materials for protecting the wearer. An arrangement of force sensitive regions defines a grid arrangement responsive to an incoming projectile. The force sensitive regions include pressure sensitive or piezoelectric characteristics such that an impact varies the electrical response of each region. A detection circuit connects to each region for sampling. A sampling of the regions computes a high velocity impact by a sudden change in the sensed electrical characteristics, such as a sudden drop in resistance between two planer sheets. The grid arrangement identifies the impact placement on the garment, and can be mapped to anatomical regions to evaluate a severity. Placement and impact force, along with GPS coordinates of the wearer, are transmitted by the detection circuit and/or in conjunction with an app on a mobile device of the wearer for alerting first responders.

Abstract: A pressure measurement device includes a platen, a pressure sensor, a signal acquisition section, and a data processing section. The pressure sensor includes a plurality of pressure-sensitive points arranged on the platen. The signal acquisition section is configured to acquire measurement data that is obtained when a measurement object in contact with a surface of the platen passes over the pressure sensor a plurality of times. The measurement object moves relative to the platen and along a circular orbit on the platen. The data processing section is configured to calculate periods in each of which the measurement object passes over the pressure sensor and to acquire period data for each of the periods from the measurement data.
