A bend test device and bend test method enable a mandrel bend test to be automatically performed. The bend test device includes a controlled motor, a drive shaft coupled to the motor, a nose piece coupled to the drive shaft, and a nose clamp for securing a device under test (DUT) to the nose piece. A control system connected to the bend test device uses a programmed control algorithm to control the bend test device. The motor is connected to the drive shaft and rotates the drive shaft in response to control signaling provided by the control system. The rotating drive shaft in turn rotates the nose piece. Rotation of the nose piece bends the mounted DUT. The motor rotates the drive shaft as defined by the software parameters and the DUT is bent back and forth across a defined radius edge.

Automated mandrel bend test

An electronic sensor device has one or more sensor electrodes and one or more electrical conductors printed on a substrate. Textile layers are attached on either side of the substrate with access to the electrical conductors provided by a conductive snap assembly. The substrate can be a TPU (thermoplastic polyurethane) film. The sensor can be a biosensor, and the biosensor is attached to a compression textile, such as a compression shirt, and electrically interconnected using printed conductive ink interconnects to a conductive snap button.

Integrating biosensor to compression shirt textile and interconnect method

An electroluminescent display is flexible and stretchable, and therefore able to be attached to a textile. All interior layers of the electroluminescent display can be made using a screen printing process which can be scaled for volume production.
