Row alarm；Button cell 4 is that warning circuit 3 and display 5 are powered；The capacitor prison of the display of the display 5 measurement arm set 1
Measured value, the measurement arm set are woven by liquid metal capacitor, and liquid metal capacitor is twisted by two metal capacitance fibers
Turning to constitute, it is about 0.8mm that its outer diameter of metal capacitance fiber, which is about 1mm internal diameter, and it is filled into liquid resin and is constituted by liquid metal,
And other end extraction electrode is sealed into one end, liquid resin constitutes dielectric layer in liquid metal capacitor, and liquid metal constitutes electricity
Pole.
The microcontroller 2 using measure the capacitor monitor value of arm set 1 as input using warning circuit 3 and display 5 as
Output, when the capacitor monitor value of measurement arm set 1 is less than preset alarm value, then 3 attonity of warning circuit, microcontroller 2 pass through
" normal " is exported with 5 connected pins of display control display 5；When measurement arm set 1 capacitor monitor value be more than preset alarm value,
Microcontroller logical 2 is crossed to be opened with warning circuit 3 and 5 connected pins of the display control switch of warning circuit 3, and warning circuit 3 is powered,
It alarms, the display of display 5 response capacitor monitor value and prompt muscular atrophy symptom.
The warning circuit 3 is specially buzzer, and after the alarm command for receiving microcontroller 2, warning circuit 3 starts bee
Ring device, alarms.
The button cell 4 is powered for system components.
The display 5 be common LED display screen, when measurement arm set 1 capacitor monitor value be less than preset alarm value, it is micro-
Controller 2 exports " normal " by controlling display 5 with 5 connected pins of display；When the capacitor monitor value of measurement arm set 1 is more than
Preset alarm value, microcontroller lead to 2 display, the 5 connected pins control display of display 5 response capacitor monitor value and prompt muscle
Atrophy million.
Preferably, it is 9 bulks that the measurement arm, which covers 1 point, convenient to realize piecemeal prison to patients arm muscle
It surveys, it is more accurate；The 1 monitoring patient of measurement arm set passes through muscle change pair according to the variation of arm muscles when instruction activity
The pressure of metallic fiber 101 changes the thickness i.e. thickness of dielectric layer of liquid resin, and then changes the size of capacitor.
The invention adopts the above technical scheme, which has the following advantages:
(1) accuracy, liquid metal capacitor have high sensitivity, and only the bounce of human pulse can clearly be felt
Know.
(2) non-invasive, using the portable muscular atrophy prevention system based on liquid metals capacitor to muscular atrophy into
Row prevention, avoids the checking step for needing artificial blood count etc. to have wound to human body in the past, improves quality of life of patients.
(3) convenience is avoided using the portable muscular atrophy prevention system based on liquid metals capacitor with with knowing
It needs be lined up etc. in hospital and expends patient's time, it is more convenient.
(4) portability, volume highly integrated using the portable muscular atrophy prevention system based on liquid metals capacitor
It is smaller, there is good portability.

Specific embodiment
The present invention will be described with reference to the accompanying drawings and examples.
A kind of portable muscular atrophy prevention system based on liquid metals capacitor, as shown in Figs. 1-2, system is by measuring
Arm set 1, microcontroller 2, warning circuit 3, button cell 4 and display 5 form, microcontroller 2, and the microcontroller 2 is to survey
The capacitor monitor value of arm set 1 is measured as input, using warning circuit 3 and display 5 as exporting；The warning circuit 3 receives
It alarms after the alarm command of microcontroller 2；Button cell 4 is that warning circuit 3 and display 5 are powered；The display
The capacitor monitor value of the display measurement arm of device 5 set 1.
Measurement arm set 1 is woven by liquid metal capacitor 102, and metal capacitance fiber 101 as shown in Figure 3 is outside it
Diameter is about that 1mm internal diameter is about 0.8mm, is filled into liquid resin 104 and is constituted by liquid metal 103, and one end is sealed another
Extraction electrode is held, two metal capacitance fibers 101 are twisted and constitute liquid metal capacitor 102, liquid resin 104 constitutes dielectric
Layer, liquid metal 103 constitute electrode, as shown in Figure 4.Using liquid metal capacitor 102 as liquid metals capacitor fiber 101,
It is knitted to form measurement arm set 1, it is 9 bulks that measurement arm, which is covered 1 point, it is convenient that piecemeal monitoring is realized to patients arm muscle, it is more smart
It is quasi-.
The principle of portable muscular atrophy prevention system based on liquid metals capacitor is as follows:
Capacitance variation principle:, 1 monitoring patient of arm set is measured according to the variation of arm muscles when instruction activity, passes through flesh
Meat changes the pressure to metallic fiber 101, changes the thickness i.e. thickness of dielectric layer of liquid resin, and then change the big of capacitor
It is small.
Steps are as follows for the use of portable muscular atrophy prevention system based on liquid metals capacitor:
Primary Stage Data setting: the capacitance of different every piece of the movements of measurement, and be input in microcontroller 2, set safe capacitance
(reduce in capacitance and be not determined as muscular atrophy then little by little), is set lower than capacitance+safe capacitance=preset alarm
Value.
4 small volume of button cell is powered for system components, is easily integrated.
Muscular atrophy detection: measurement arm set 1 is coated on patient's arm, patient is instructed to transport according to fixed movement
It moves, for example picks up cup, while measuring arm 1 arm segment of set not touch other objects in addition to arm, while monitoring capacitor
Value.
Muscular atrophy testing result: when the capacitor monitor value of measurement arm set 1 is less than preset alarm value, then warning circuit 3
Attonity, microcontroller 2 export " normal " by controlling display 5 with 5 connected pins of display；When the capacitor of measurement arm set 1
Monitor value is more than preset alarm value, and microcontroller logical 2 is crossed to be opened with warning circuit 3,5 connected pins of display control warning circuit 3
It closing and opens, warning circuit 3 is powered, it alarms, the display of display 5 response capacitor monitor value and prompt muscular atrophy symptom.
Repeat aforesaid operations 3 times, if 3 times all for it is same as a result, if be determined as " normal " or muscular atrophy sign.
