▎ 摘　　要

NOVELTY - The device has a hair follicle detection end provided with a hair follicle detection probe, a conversion module and a signal processing module. The hair follicle detection probe is provided with a skin image collector and a graphene humidity sensor. The conversion module converts scalp image information into scalp humidity information by the hair follicle detection probe. The signal processing module amplifies first electrical signal and second electrical signal. A terminal device is connected to the signal processing module for displaying the first electrical signal and the second electrical signal after processing. The hair follicle detecting probe is connected with the terminal device through Zigbee, Wireless Fidelity (Wi-Fi) or Bluetooth modules. The terminal device is selected as mobile phone, computer or pad. USE - Graphene-based hand-hold hair follicle detection device. ADVANTAGE - The device can provide scalp humidity image data to provide doctors with better effective information. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a graphene-based hand-hold hair follicle detection method. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a graphene-based hand-hold hair follicle detection device.
