Title:
WEARABLE ULTRASONIC HAPTIC FEEDBACK SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/107344
Kind Code:
A1
Abstract:
A wearable ultrasonic haptic feedback system includes: a substrate layer (101); an ultrasonic transmitter matrix layer (103) disposed above the substrate layer (101) and including a plurality of ultrasonic transmitters (201); a converter matrix layer (105) disposed below the substrate layer (101) and including a plurality of converters (301); a first control unit (107) connected with the ultrasonic transmitter matrix layer (103); an RF receiver (109) connected with the first control unit (107); a second control unit (111) connected with the converter matrix layer (105); and an RF transmitter (113) connected with the second control unit (111). The RF transmitter (113) is configured to transmit the electrical signal through an RF signal of a preset frequency. The RF receiver (109) is configured to receive the RF signal transmitted by the RF transmitter (113) and restore the electrical signal from the RF signal.
