The figure shows a fully fabricated, functional fingertip designed for prosthetic hand applications. It can also be used in humanoid robots. This fingertip is origamically folded to approximate the structure of an average human fingertip.
The fingertip features a dense arrangement of barometric sensors, each measuring 2x2x1 mm. The module's fingertip area incorporates 22 barometric sensors capable of detecting temperature and pressure changes. It is designed and fabricated using flexible PCB technology.
Sensor data acquisition is managed by an onboard 32-bit microcontroller operating at an 8 MHz clock speed.
