Kit overview The stretch sensor kit enables you to quickly get hands on with Electroactive Polymer (EAP) capacitive stretch sensors. The kit can be used for unobtrusive monitoring of soft structures such as the human, textiles and rubbers. It is ideal for prototyping wearable motion capture or for characterising the sensors with a view to product integration. Contents The stretch sensor kit includes: Two stretch sensors (see stretch sensor datasheet below), One measurement electronics (see electronics datasheet below), Wires for sensors and PC connections, Software displaying and saving realtime measurement data on a PC.

Overview  –  Stretch  Sensor  Kit    (Preliminary)  

Uniqueness  Soft  –  Unobtrusively  measuring  movement  and  motion.  Light  –  7x  lighter  than  metal  sensors.  Robust  –  highly  robust  against  shock,  overload  and  misalignment.  Versatile  –  highly  versatile  in  shape  and  sizes.  

             Elastomer  stretch  sensor  (04D0010)    Made   from   high   quality   elastomer   materials,   the   LEAP   Technology   stretch  sensor  is  a  versatile,  highly  elastic  capacitive  strain  gauge.    

• Highly  stretchable  sensor  enables  unobtrusive  motion  capture  of  human,  machines,  and  complex  surfaces;  

• Capacitive  sensing  characteristic  ensures  accurate  and  repeatable  measurements;  

• Easy  textile  integration  due  to  its  low  profile  and  textile  based  cabling;  • Inherently  tolerant  to  shock,  vibration  and  misalignment;  • Minimum  response  to  applied  surface  pressure;  • Washable.

Uniqueness  Soft  –  Unobtrusively  measuring  movement  and  motion.  Light  –  7x  lighter  than  metal  sensors.  Robust  –  highly  robust  against  shock,  overload  and  misalignment.  Versatile  –  highly  versatile  in  shape  and  sizes.  

             

Capacitive  sensor  electronics  (004T0014)  This  easy  to  use  electronics  box  is  designed  for  capacitive  sensor  measurements.  The  included  circuit  and  software  is  capable  of  measuring  capacitors  with  variable  capacitance  as  well  as  variable  equivalent  serial  resistance  (ESR),  thus  making  it  ideal  for  electroactive  polymer  (EAP)  sensor  measurements.  Due  to  its  universal  measurement  technique,  this  device  can  measure  EAP  sensors  of  LEAP  Technology  as  well  as  those  from  third  parties.  The  circuit  is  supplied  with  proprietary  PC  software  that  enables  you  to  measure,  save,  and  display  real-­‐time  data.  New  versions  of  the  electronics  are  planned  to  include  two  analogue  output  channels  representing  the  sensor  measurement  in  analogue  format  (0-­‐5V)  enabling  you  to  transfer  sensor  measurements  to  a  third  device  such  as  an  Arduino  board.  Other  customisation  is  also  possible  due  to  the  versatile  design  and  choice  of  on  board  microcontroller  -­‐  please  enquire.
