Sketch-Recording Pen

Sketch-Recording-Pen-01-580w-40

     This is a sketch-recording pen that records handwriting and sketches in the pen’s internal memory.  This allows writers and artists to sketch and transfer the information to the computer.  The pen senses pressure on the tip using piezoelectric strain gauges or by measuring capacitance between the stylus and the barrel.

     The ink cartridge, is held with an O-ring.  Four metal sensing strips are arranged around the pen barrel and are air spaced from the tip and wired to the pen’s circuitry.  The varying capacitance is converted into X-Y data and stored in the pen’s RAM.
