-In gluing [[:sensors:force-sensitive resistor|FSR]] sensors to a pair of gloves on the tip of each finger, we have frequently found that they will tear in half.  This often takes place at the boundary between the sensor and the soldered wire.  Differentials in physical stiffness between the wire and the FSR material seem to cause mechanical stress at that boundary.  Stretching, rotation, and bending through normal use eventually cause the FSR material to rip in half.  We recommend that you find ways of attaching sensors such that the sensing material does not experience any movement or stress during normal use.+In gluing [[:sensors:force-sensitive resistor|FSR]] sensors to a pair of gloves on the tip of each finger, we have frequently found that they will tear in half.  This often takes place at the boundary between the sensor and the soldered wire.  Differentials in physical stiffness between the wire and the FSR material seem to cause mechanical stress at that boundary.  Stretching, rotation, and bending through normal use eventually cause the FSR material to rip in half.  We recommend that you find ways of attaching sensors such that the connection point does not experience any movement or stress during normal use. Applying hot glue to the connection boundary can avoid stress at the connection, but makes disassembly and connection debugging difficult after drying.
