SensorTape: Modular and Programmable 3D-Aware Dense Sensor Network on a Tape
summary
A flexible, cuttable tape embeds programmable sensor nodes (Arduino-compatible microcontroller, 6-axis IMU, time-of-flight IR proximity, RGB LED) in diamond cells and runs a master-driven I2C-like bus at ~100 Hz to stream shape and proximity. A 2.3-meter 2.3-meter prototype holds 66 nodes and reports ~6.4° rotation error; theoretical limits are ~180 nodes by power and ~1,088 by parasitic capacitance. Users reconnect cuts with conductive tape or solder; applications include a 3D ruler and posture-sensing wearables.
