However, there are very few fingertip tactile interactive devices at present.

The traditional fingertip tactile interactive device includes a sensor, a data sampling chip, and a main control board with a main control chip; the digital-analog interface of the data sampling chip is connected to the sensor to collect sensor data, and the connection between the main control chip and the data sampling chip is They are connected through a communication interface, and the main control board processes and analyzes the collected data; among them, most of the sensors use resistive pressure sensors, which are similar in principle to sliding rheostats, and the resistance value of the device changes through external pressure. The voltage value uses the principle of voltage division to detect the voltage value to indirectly detect the resistance value. This scheme has the disadvantages of complex wiring of the device, inaccurate measurement, and large volume (such as patent CN101258389B)
