2.  Need › Sample fingernail vibrations at least 1000Hz › Log and display sensor data › Correlate new-sensor data with existing-sensor data  Want › Add sensors to detect temperature, pressure, sound, light, and moisture.

3.  Need › One accelerometer per finger › One nail per finger (3 nails per hand) › Sexy circuit boards › Nails need to cosmetically emulate human nails › Localized hardware must fit within the upper segment of the finger  Want › Stay under $250 budget › Minimize meetings › Get Published

4.  1000Hz is sufficient sampling rate  Suitable nail material exists  Accelerometers of sufficient sensitivity exist

5. Nail + Robot Hand + Scratching
