In robot application, use sensor of the film that suppress report to be able to let a robot have the address hand department action like the mankind, have acute touch, the change of pressure can be felt when taking fetch put oneself in another’s position, control the output of good grab force, sensor tilts on union, will can let a robot have more the control ability of actor, this is a when the robot develops important level. The pressure of delicacy of sensor of the film that suppress report conveys feeling ability, union tilts the control application that sensor can be a robot brings new turning point. The article will introduce the film that suppress report for you sensor and tilt the technical development of sensor and application, and by Murata (village cropland makes place) brings solution.

More environment the stuff of the film that suppress report with friendly, more expensive sensitivity

The film that suppress report is use a kind to say to get together lactic acid (Polylactic Acid, PLA) material, get together lactic acid serves as a kind ” biology degradation polymer ” , have but the intensity with general oil plastic abstraction mixes compare shape quality, from 1995 the left and right sides begins to be paid close attention to, already served as an environment now friendly model polymer by wide for acknowledge. The lactic acid of PLA raw material is to pass lactobacillus to undertake what make and become lactic acid ferments to the starch that extracts from inside the plant. Starch comes from floral photosynthesis, outside the sources of energy that in eliminating production process, uses, making to carbon was used to counteract sexual material in the deserted, lifecycle that decompose, because won’t this increase the CO in atmosphere? .

PLA has the tall transparency that polymer of degradation of other live thing does not have, its light transmitance exceeded 93% Yakeli’s even. We waited for the one part of common egg box and tomato box to use PLA in the supermarket in daily life. PLA is to serve as an environment normally friendly model the polymer of low plant sex that polymer uses, but the sex suppressing report of this polymer has unique character. The constant suppressing report of PLA (the D that suppress report is invariable) control for 7 ～ 12pC/N, as smaller as the photograph such as PZT, but the opposite dielectric constant of PLA is very low, it is about 2.5, because this presses electric output constant (T of ε of constant of G of = pressing report, G=d/ ) the value is greater. Accordingly, of PLA pass feeling sensitivity tall. Undertake in order to press electric output constant comparative, its get together with what press electric constant to be times above of PLA 4 slant fluorine ethylene (PVDF) roughly identical.

Because squash,the film suppressing report that uses PLA to make is in or be out of shape produce distortion (stretchy, contractive) when, polarization of generation and proportionate of distortion of surface of the film that suppress report. The charge that polarization generates is voltage through I/V converter changeover, regard imitate signal as output, thereby can be informed the pressure change that the film that suppress report gets.

Tall sensitivity is pressed pressure those who detect is flexible thin model sensor of the film that suppress report

Murata uses proprietary to control electric technology research and development ” Picoleaf ” , it is one can undertake tall sensitivity is pressed pressure those who detect is flexible thin model sensor. It uses Murata proprietary to press report to the technology is developed and be become, smaller than traditional sensor, thinner, can save installation space, in thin model, assembled the respect such as function and wear to come true to reform, aim to raise need man-machine interface (HMI) the function that conducts the product of feeling, have easy assemble character and wear. For appropriative sensor, electrode is pressworked or the layer overwhelms thin and provide the organic film suppressing report with flexible height to go up. This film can arrive through installation of double-faced adhesive plaster on equipment, do not need stickup course thereby.

A rope for towing a boat that Picoleaf conduces to implementation equipment is small change, although combine monitor and feeling face plate to use, also can save a space. Picoleaf has tall sensitivity, because this uses a sensor only, can realize what large monitor makes a range to press pressure detect, also applicable at detecting the body such as pulse of the maintenance of movement of grab of the involuntary muscle quiver of the tiny displacement of class of 1 μ M, human body, hand, human body collects signal detect.

Picoleaf has blame heat commentate electric sex does not change this kind because of temperature the content sex of polarization, be waited for because of temperature, sunshine, semiconductor calorific the sensitivity that cause changes and interference is small. Picoleaf has low power comsumption, the power comsumption of sensor parts of an apparatus is 0, drive also can be designed with amplifier for electric current of low power comsumption (10 μ A is controlled) . Picoleaf is flexible structure, can bend stickup designing the curved surface equipment with higher sex.

The Picoleaf that Murata uses its proprietary to press electric technology to come true can be installed inside narrow space, compare with the sensor photograph previously, it can come true thin model change and rise assemble gender and wear. Picoleaf detects through combination circuit, can obtain the output that is based on speed of displacement of the film that suppress report, output character through using this, can serve as by pressure detect, grasp hold detect, biology signal detects wait for a variety of sensor application.

Picoleaf can be used at pressing to press detected application, can use by pressure detect character is used as UI sensor, picoleaf the setting is in touch accuse a pen to go up, can detect hand holds held position, its are not confined to a contact, still can pass detect of hand by press an action in order to be on guard misoperation.

Picoleaf also can be used at the application that biology signal detects, can use the feature of tall sensitivity of sensor of the film that suppress report, as detect in biology signal ” pulse and breath ” sensor is used. At present academia has had many paper to publish, discuss use but the sensor suppressing report of biology degradation will detect the heartbeat of human body surface and ventilatory frequency, the biology signal that represented the sensor that suppress report detects essence of life is spent definitely had obtained confirm.

Murata offers a variety of product forms, include sensor component monomer, be a kind but stickup be in advocate the design of substrate, still sensor component combines layout, it is position of a kind of sensor and the design with detached substrate, and part of sensor component union installs layout, sensor position and substrate depart, be a kind advocate the design that installation component area does not have on substrate.

Of Picoleaf detect circuit is formed by I/V converter and amplifier circuit, should press electric film warp (as a result of pressure or be out of shape and drawing or systole) when, meeting generation and the warp that bring to bear on measure proportionate polarization volume, the charge that its can generate Picoleaf is voltage through I/V converter changeover, regard imitate signal as output, can inspect need to undertake magnify and be adjustmented, so that can be undertaken handling by general ADC or CPU, and the effect that does not suffer sensor capacitance and stray electric capacity. At present the proposal uses schism circuit, the Picoleaf that Murata is including signal to handle a function in development is special ASIC, predict to began to offer 2025.

Picoleaf sensor is had be out of shape conspicuously detect ability

The character suppressing report of Picoleaf sensor can detect ” displacement direction ” and ” displacement speed ” . On displacement direction, through detecting ” hill form fold ” be out of shape, displacement direction can output Picoleaf referenced voltage side, if detect ” cereal form fold ” be out of shape, displacement direction can output negative side. Besides displacement direction, still can calculate according to peak value voltage displacement speed, peak value voltage and displacement rate increase into scale.

In addition, use Picoleaf sensor to output inverting character, will press and can release behavioral application to be not had mediumly for UI seam switch, with be being configured as switch. If install Picoleaf the object of periodic vibration to go up, picoleaf can detect periodic vibration, because this can use as,condition detects sensor.

The ply of Picoleaf has 0.2 millimeter only or smaller, product measure exceeds compact, for 2×10 millimeter, although be used with monitor or union of feeling face plate, also can save a space. Of the equipment that it still can design along height curve the surface stickup, include special form, twine for example go up in cylinder. Picoleaf has tall sensitivity, can detect not only the displacement of level of 1 micron volume, individual sensor still can detect large monitor is whole exterior pressure. It can be used at detecting involuntary muscle moves, for example quiver, grab and pulse.

Picoleaf has blame heat commentate report is characteristic, as a result of nonexistent by heat (for example temperature, sunshine or semiconductor) the drift that cause, noise is accordingly less, because this is algorithmic easier compose is built, and sensor itself power comsumption is 0, drive can design low power comsumption with enlarge circuit (A of about 10 μ ) .

Picoleaf can be used at a variety of pressure to detect application

The light transmittance of Picoleaf exceeds 90% , can install the area of indication face plate in need diaphaneity. Detect the pressure of the UI function that touchs screen and Picoleaf ability photograph is united in wedlock, can realize the HMI that is different from common feeling screen, more be based on human behavior principle. Can design on application for pressure detects the dovish input UI that spark, use be out of shape detect the blame finger such as implementation pen inputs equipment, and detect through applying a variety of pressure function, found real software clavier experience.

If you are coming true new can apparel difficulty is encountered when the concept, you can use Picoleaf light, thin, short and agile structure will add new function, maintain design integrality at the same time. The installation flexibility of Picoleaf can be solved easily exceed little space, curved surface and other challenge. Detect through pressure applying on narrow space and curved surface, found the UI that has dovish operation sex, make equipment is had wear away to detect with ／ or capture function (use tall sensitivity) , applicable can apparel equipment detects the biology signal such as pulse, breath, the gymnastical equipment that there have been those who use Murata to press place of Picoleaf of electric film sensor to produce on market at present is rolled out.

When the design, also can use Picoleaf to gift robot product touch, through using these height sensitive parts of an apparatus can connect the character that receives any thing or place, picoleaf can be the development of the robot trade that uses tactile information to make contribution, can apply Picoleaf at the finger tip of manipulator, be out of shape and adjust the adjustment of capture force what the contact causes in order to detect with soft hard object, no matter its pliability how, can make individual manipulator can capture a variety of objects. Picoleaf can receive remote control robot to feedback in order to quantify touch repeatedly, can provide actualer environmental information for VR air man thereby, picoleaf also but as in-house as exercise robot layout agglutinate, use at detecting the in-house and unusual situation such as layout ageing.

Picoleaf photograph relatively wait for a product at type of meet an emergency, capacitance type, acceleration type, mechanical software type, dimension of its standard items has 3×17 Mm only, ply has 0.25mm only (0.1mm back glue) , assemble a method to be able to use the adhesive such as adhesive plaster to undertake stickup, have force to detect ability, sensitivity achieves 1 μ M, can detect be out of shape fast degree is occupied, current part can be used on circuit design, use interface of join of 4 needles ZIF, the typical cost of Vdd of power source voltage is 3.3V, power comsumption is less than 10 μ A, answer time to be less than 10ms, support curved surface design, have more advantages.

High-powered tilt the requirement that sensor satisfies harsh environment
