[0060] Figure 1 FIG. 1 shows a wearable device 100 according to an embodiment, Figure 2 FIG. 4 shows an electrode arrangement of a wearable device 100 according to an embodiment. Figure 3 FIG. 4 shows a usage state of the wearable device 100 according to an embodiment.

[0061] See also Figures 1 to 3 According to one embodiment, a wearable device 100 can provide a smoking effect. The wearable device 100 may include: a housing 110; a first stimulation unit 121 disposed on one side of the housing 110 to provide a stimulation signal to a first part of the user; a second stimulation unit 122 disposed on one side of the housing 110 to provide a stimulation signal to a second part of the user; and a controller that controls the first stimulation unit 121 or the second stimulation unit 122. The wearable device 100 may also include a third stimulation unit 123 that provides a stimulation signal to a third part of the user.

[0062] In one embodiment, the housing 110 can be worn in a manner such that at least a portion thereof contacts the body of the user O. The housing 110 can be configured as a helmet or hat, etc., wearable on the head of the user O. For example, the housing 110 can be made of metal or plastic. In various embodiments, a portion of the housing 110 (e.g., the frame) can be made of metal, while other portions of the housing 110 can be made of plastic.

[0063] The housing 110 can be securely worn on the head of the user O via a wearing means 111. For example, the wearing means 111 can take the form of a band or strap connecting one end of the housing 110 to the other, and can be made of various materials (e.g., rubber, plastic, metal, etc.). The wearing means 111 can be detached from the housing 110 according to the user O's preferences, thereby adding various aesthetic features to the wearable device 100. In another example, the wearing means 111 can be omitted, and the housing 110 can be pressed into the head of the user O to achieve wearability.

[0064] The housing 110 may include a first surface 110-1 that contacts the user O, a second surface 110-2 opposite the first surface 110-1, and side surfaces located between the first surface 110-1 and the second surface 110-2. A first stimulation unit 121, a second stimulation unit 122, and a third stimulation unit 123 may be arranged within the interior space of the housing 110 defined by the first surface 110-1, the second surface 110-2, and the side surfaces, and at least a portion of each of the first stimulation unit 121, the second stimulation unit 122, and the third stimulation unit 123 may be exposed outside the first surface 110-1. The interior space of the housing 110 may also accommodate a memory, a communication unit, a power supply, and the like.

[0065] For example, the memory is hardware that stores various data processed within the wearable device 100 and can store data processed by the controller and data to be processed. The memory is at least one storage medium selected from the group consisting of a flash memory type memory, a hard disk type memory, a multimedia card micro type memory, a card type memory (such as an SD or XD memory), a random access memory (RAM), a static random access memory (SRAM), a read-only memory (ROM), an electrically erasable programmable read-only memory (EEPROM), a programmable read-only memory (PROM), a magnetic storage device, a magnetic disk, and an optical disk. The memory can store the operating time, maximum usage time, current usage time, and smoking pattern data of the wearable device 100, etc.

[0066] For example, the communication unit may include a short-range communication unit and a wireless communication unit. The short-range wireless communication unit includes a Bluetooth communication unit, a Bluetooth Low Energy (BLE) communication unit, a near-field communication unit, a WLAN (Wi-Fi) communication unit, a Zigbee communication unit, an infrared (IrDA, infrared Data Association) communication unit, a WLAN direct connection (Wi-Fi Direct, WFD) communication unit, an ultra-wideband (UWB) communication unit, an Ant+ communication unit, etc., but the implementation method is not limited thereto. The wireless communication unit may include a cellular network communication unit, an Internet communication unit, a computer network (such as LAN or WAN) communication unit, etc., but the implementation method is not limited thereto.

[0067] In one embodiment, a power supply or stimulation generator 112 may be disposed on one side of the housing 110. The power supply or stimulation generator 112 may be connected to the first stimulation unit 121, the second stimulation unit 122, and the third stimulation unit 123 via a connection line 113. The power supply or stimulation generator 112 may provide power or electrical stimulation signals for brain stimulation to the first stimulation unit 121, the second stimulation unit 122, and the third stimulation unit 123.

[0068] In another example, the power supply or stimulation generator 112 can be arranged separately from the housing 110. For example, the power supply or stimulation generator 112 can be configured as a neckband and worn around the neck of the user O. In this case, the power supply or stimulation generator 112 can still be connected to the first stimulation unit 121, the second stimulation unit 122, and / or the third stimulation unit 123 via the connecting line 113.

[0069] In one embodiment, the controller of the wearable device 100 can control the first stimulation unit 121, the second stimulation unit 122, and / or the third stimulation unit 123, so that the first stimulation unit 121, the second stimulation unit 122, and / or the third stimulation unit 123 generate electrical stimulation signals that can induce an awakening state that achieves a smoking effect. For example, the controller can be housed in the internal space of the housing 110 to connect to the first stimulation unit 121, the second stimulation unit 122, and / or the third stimulation unit 123. For another example, the controller can be housed in another electronic device (e.g., a mobile communication terminal) located outside the housing 110, and provide control signals to the first stimulation unit 121, the second stimulation unit 122, and / or the third stimulation unit 123 through the communication unit.

[0070] In one embodiment, the first stimulation unit 121, the second stimulation unit 122, and / or the third stimulation unit 123 may include at least one electrode for performing electrical stimulation. The electrode may be connected to a controller. The electrode may be connected to a power source or stimulation generator 112.

[0071] For example, the portion of the electrode exposed from the first surface 110-1 of the housing 110 may be attached with an electrode pad. The electrode pad may contact the scalp of the user O. The electrode pad may be made of a hydrogel material to enable multiple uses. The electrode pad may be replaced after reaching its service life.

[0072] In particular, refer to Figure 2 , the electrode can be composed of a plurality of electrodes (A1, A2, C3, C4, Cz, F3, F4, F7, F8, Fp1, Fp2, Fz, O1, O2, P3, P4, Pz, T3, T4, T5, T6).

[0073] In one embodiment, the first stimulation unit 121 may include a portion of electrodes ( F3 , Fz , F4 ) arranged at a position corresponding to a first part of the user O (eg, a frontal lobe).

[0074] In one embodiment, the second stimulation unit 122 may include a portion of electrodes ( C3 , Cz , C4 ) arranged at a position corresponding to a second part of the user O (eg, parietal lobe).

[0075] In one embodiment, the third stimulation unit 123 may include a portion of electrodes (T5, P3, Pz, P4, P6, O1, O2) arranged at a position corresponding to a third part of the user O (eg, occipital lobe).

[0076] The controller of the wearable device 100 may provide an electrical stimulation signal to the first stimulation unit 121, the second stimulation unit 122 and / or the third stimulation unit 123 to change the user's O state into the awake state. Figure 3 , the controller of the wearable device 100 can provide an electrical stimulation signal to the electrode F7 or the electrode F8 arranged at a position corresponding to the dorsal prefrontal cortex of the user O, so as to apply electrical stimulation to the dorsal prefrontal cortex of the user O. The electrode F7 can be configured as an anode (Anode, +), and the electrode F8 can be configured as a cathode (Cathode, -), and the controller of the wearable device 100 can cause a current to flow from the electrode F7 through at least a portion of the dorsal prefrontal cortex of the user O and to the electrode F8. At this time, the excitability of the neurons in the dorsal prefrontal cortex close to the electrode F7 increases, while the excitability of the neurons in the dorsal prefrontal cortex close to the electrode F8 decreases, thereby maximizing the awakening effect of the user O.

[0077] In one embodiment, the controller of the wearable device 100 can control the first stimulation unit 121, the second stimulation unit 122 and / or the third stimulation unit 123 so that the first stimulation unit 121, the second stimulation unit 122 and / or the third stimulation unit 123 generate brain stimulation signals that can induce an awakening state to achieve a smoking effect.

[0078] In one embodiment, the brain stimulation signal may be electrical stimulation. The brain stimulation signal may be transcranial alternating current stimulation (tACS), which uses sinusoidal waves of varying frequencies with a maximum current of less than 2 mA to influence the periodic excitability of cerebral cortical neurons and induce changes in brain functions such as cognition and memory.

[0079] In one embodiment, the controller of the wearable device 100 can control the first stimulation unit 121, the second stimulation unit 122 and / or the third stimulation unit 123 to generate a brain stimulation signal that can reduce at least one of the delta (δ) wave area or theta (θ) wave area of ​​the user's O brain wave, or increase the brain stimulation signal in the beta (β) wave area of ​​the user's O brain wave.

[0080] Delta waves, which can range in frequency from 1Hz to 4Hz, are associated with unconscious bodily activities such as heartbeat and digestive control. Increasing the power associated with delta waves can induce a state of stability and sleep, thereby achieving relaxation, while decreasing the power associated with delta waves can induce a state of arousal. Theta waves, which can range in frequency from 4Hz to 8Hz, primarily occur during meditation or when the hippocampus is activated. The hippocampus controls memory. Increasing the power associated with theta waves can lead to states of inspiration, insight, or connecting fragments of memory; decreasing the power associated with theta waves can lead to anxiety, stress, and a lack of self-awareness. Beta waves, which can range in frequency from 12Hz to 25Hz, are typically present during arousal, so an increase in beta waves can indicate arousal. Increasing the power associated with beta waves can induce arousal, such as cognitive thinking; decreasing the power associated with beta waves can induce a state of relaxation.

[0081] Figure 4 Shown are the user's brain waves before and after inhaling a cigarette or e-cigarette.

[0082] Figure 4The graph measured the subjects' brain waves (ElectroEncephaloGram, EEG) before and after inhaling cigarettes or e-cigarettes, using an electrophysiological method that records brain electrical activity through electrodes. The specific experimental method is as follows: EEG sensors (brain wave measurement sensors) are attached to multiple locations on the subjects' heads, and the subjects are divided into two groups: the cigarette group and the e-cigarette group. The brain waves of the two groups are measured before and after smoking. The analysis results of the power spectral density (PSD) before and after smoking are shown as follows: Figure 4 As shown in the diagram. Figure 4 Full-band power analysis results show that smoking leads to a decrease in low-frequency areas (e.g., delta and theta waves) and an increase in high-frequency areas (e.g., beta waves). For example, the power spectral density of brain waves above 10 Hz generally increases.

[0083] Figure 5a and Figure 5b Shown are brain stimulation sites for reducing delta waves. Figure 6a and Figure 6b Brain stimulation sites for reducing theta waves are shown. Figure 7a and Figure 7b Brain stimulation sites for increasing beta waves are shown.

[0084] Figure 5a The delta wave-related brain wave change patterns before and after inhaling cigarettes and e-cigarettes are shown. Figure 5b Shown are the brain stimulation sites of user O for reducing delta waves.

[0085] refer to Figure 5a In terms of delta waves, e-cigarettes activated the occipital and parietal lobes, while cigarettes activated the occipital, parietal, and frontal lobes (especially the dorsal prefrontal cortex). Both cigarettes and e-cigarettes activated the occipital and parietal regions.

[0086] refer to Figure 5b According to one embodiment, the controller of the wearable device 100 can reduce the delta wave by activating the second stimulation unit 122 and / or the third stimulation unit 123, thereby providing a smoking effect. The controller can activate the electrodes (C3, Cz, C4) of the second stimulation unit 122 and / or the electrodes (T5, P3, Pz, P4, T6, O1, O2) of the third stimulation unit 123 to provide electrical stimulation to the parietal lobe and / or occipital lobe, thereby effectively reducing the delta wave of the user O.

[0087] For example, the controller of the wearable device 100 can activate the second stimulation unit 122 and / or the third stimulation unit 123, which can provide electrical stimulation that reduces the power spectral density of the user's brain waves in the 1Hz to 4Hz frequency range by 0.3dB to 0.9dB.

[0088] Figure 6a The change patterns of brain waves related to theta waves before and after inhaling cigarettes and e-cigarettes are shown. Figure 6b Shown are the stimulation sites on the brain of user O for reducing theta waves.

[0089] refer to Figure 6a Regarding theta waves, e-cigarettes can activate the occipital lobe, while cigarettes can activate the frontal lobe (dorsal prefrontal cortex).

[0090] refer to Figure 6b According to one embodiment, the controller of the wearable device 100 can reduce the theta wave of the user O by activating the first stimulation unit 121 and / or the third stimulation unit 123. At this time, the electrodes (F3, Fz, F4) corresponding to the frontal lobe (dorsal prefrontal lobe) among the multiple electrodes of the first stimulation unit 121 can be activated. The controller can provide electrical stimulation to the frontal lobe (dorsal prefrontal lobe) and / or the occipital lobe by activating the electrodes (F3, Fz, F4) of the first stimulation unit 121 and / or the electrodes (O1, O2) of the third stimulation unit 123, thereby effectively reducing the theta wave of the user O.

[0091] For example, the controller may activate the first stimulation unit 121 and / or the third stimulation unit 123, and the first stimulation unit 121 and / or the third stimulation unit 123 may provide electrical stimulation that reduces the power spectral density of the user's O brainwave in the 4Hz to 8Hz frequency range by 0.2dB to 0.5dB.

[0092] Figure 7a The pattern of changes in brain waves related to beta waves before and after inhaling cigarettes and e-cigarettes is shown. Figure 7b Shown are the stimulation sites of the brain of user O for reducing beta waves.

[0093] refer to Figure 7a , for beta waves, e-cigarettes can activate the occipital and parietal lobes, while cigarettes can activate the occipital, parietal, and frontal lobes.

[0094] refer to Figure 7bThe controller can increase the user's beta wave by activating the first stimulation unit 121, the second stimulation unit 122, and / or the third stimulation unit 123. The controller can provide electrical stimulation to the frontal lobe, parietal lobe, and / or occipital lobe by activating the electrodes (F3, Fz, F4) of the first stimulation unit 121, the electrodes (C3, Cz, C4) of the second stimulation unit 122, and / or the electrodes (T5, P3, Pz, P4, T6, O1, O2) of the third stimulation unit 123, thereby effectively increasing the user O's beta wave.

[0095] For example, the controller can activate the first stimulation unit 121, the second stimulation unit 122 and / or the third stimulation unit 123, and the first stimulation unit 121, the second stimulation unit 122 and / or the third stimulation unit 123 can provide electrical stimulation that increases the power spectral density of the user's O brain wave in the frequency range of 12Hz to 25Hz by 0.1dB to 1.1dB.

[0096] refer to Figure 8 It can be seen that the wearable device 100 according to one embodiment is used to achieve Figure 4 Same / similar results as shown for actual smoking.

[0097] Regarding reducing the delta wave which is a low-frequency area, electrical stimulation is provided to the parietal lobe and / or occipital lobe of the user O by activating the second stimulation unit 122 and / or the third stimulation unit 123 of the wearable device 100, thereby effectively reducing the delta wave to maximize the arousal of the user O associated with providing a smoking effect.

[0098] For reducing theta waves which are low-frequency areas, electrical stimulation is provided to the dorsal prefrontal lobe and / or occipital lobe of the user O by activating the first stimulation unit 121 and / or the third stimulation unit 123 of the wearable device 100, thereby effectively reducing theta waves to maximize the arousal of the user O associated with providing a smoking effect.

[0099] With respect to increasing beta waves as a high-frequency area, electrical stimulation is provided to all areas of the brain of the user O by activating the first stimulation unit 121, the second stimulation unit 122 and / or the third stimulation unit 123 of the wearable device 100, thereby effectively increasing beta waves to maximize the arousal of the user O associated with providing a smoking effect.

[0100] The electrical stimulation provided by the first stimulation unit 121, the second stimulation unit 122, and / or the third stimulation unit 123 may be transcranial alternating current stimulation (tACS), which uses sinusoidal waves of varying frequencies with a maximum current of less than 2 mA to influence the periodic excitability of neurons in the cerebral cortex and induce changes in brain functions such as cognition and memory. The applied current may be 1 mA to 3 mA, and the stimulation time may be 10 to 30 minutes.

[0101] In one embodiment, the controller of the wearable device 100 can control the stimulation units (e.g., the first stimulation unit 121, the second stimulation unit 122, the third stimulation unit 123) so that the stimulation units provide brain stimulation signals in a frequency range above 10 Hz that can increase the user's O brain waves.

[0102] In one embodiment, the controller of the wearable device 100 can control the stimulation unit to provide a first electrical stimulation that reduces the power spectral density (PSD) of the user's brain waves in the frequency range of 1 Hz to 4 Hz by 0.3 dB to 0.9 dB.

[0103] In one embodiment, the controller of the wearable device 100 can control the stimulation unit to provide a second electrical stimulation that reduces the power spectral density of the user's brain waves in the frequency range of 4 Hz to 8 Hz by 0.2 dB to 0.5 dB.

[0104] In one embodiment, the controller of the wearable device 100 can control the stimulation unit to provide a third electrical stimulation that increases the power spectral density of the user's brain waves in the frequency range of 12 Hz to 25 Hz by 0.1 dB to 1.1 dB.

[0105] In one embodiment, the wearable device 100 may further include a verification component for verifying the effect of smoking. The verification component may measure heart rate variability (HRV).

[0106] Heart rate variability (HRV) combines indicators such as heart rate (HR), mean RR (mean ECG peak interval), SDNN (standard deviation of all NNs (RRs), stress resistance (physiological resilience), RMSSD (root mean square of the difference between adjacent NNs (RRs), parasympathetic nervous system indicator (related to cardiac electrical stability)), low frequency (relatively low frequency range, an indicator of sympathetic nervous system activity), and high frequency (relatively high frequency range, related to respiratory activity). The healthier the individual, the more complex the HRV. An increased heart rate indicates increased workload (physical activity) and a state of excitement; a decreased SDNN indicates a monotonic HRV signal, decreased stress resistance, and decreased overall health; a decreased RMSSD indicates cardiac abnormalities; and an increased LF may indicate decreased HRV.

[0107] Figures 9a to 9e The diagram shows the user's heart rate variability index before and after inhaling a cigarette or an e-cigarette. For e-cigarettes, the diagram shows the impact of inhaling nicotine-containing e-cigarettes on electrocardiogram measurement indicators before and after inhaling. Figure 9a Shows the average heart rate. Figure 9b shows the RMSSD, Figure 9c The NN standard deviation is shown, Figure 9d Shows low frequencies, Figure 9e High frequencies are shown. Figures 9a to 9e , the mean heart rate and low frequency increased, while the standard deviation of the neural network (SDNN), RMSSD, and high frequency decreased. This can be regarded as a physiological and psychological state similar to arousal in response to stimulation.

[0108] Figure 10a and Figure 10b FIG. 4 shows changes in a heart rate variability indicator (eg, autonomic nerves) caused by electrical stimulation of the wearable device 100 according to an embodiment. Figure 10a shows the autonomic nerve map before electrical stimulation, Figure 10b Figure 2 shows the autonomic nerve diagram after electrical stimulation. Figure 10a and Figure 10b As shown, it was confirmed that autonomic balance improved after electrical stimulation compared to before stimulation. This can be regarded as a physiological and psychological state similar to arousal in response to stimulation.

[0109] In one embodiment, a verification component can be used to verify the awakening effect achieved after the wearable device 100 is stimulated (providing a smoking effect). For example, the verification component can use the SDNN or RMSSD in the heart rate variability indicator to verify whether the indicator decreases before and after the stimulation and / or the degree of decrease, thereby verifying whether a sufficient awakening effect (smoking effect) has been achieved.

[0110] In one embodiment, the controller of the wearable device 100 may determine the activity level of the first stimulation unit 121, the second stimulation unit 122, and / or the third stimulation unit 123 based on the smoking indicator (e.g., heart rate variability indicator) signal from the verification component. For example, if the degree of reduction in the SDNN or RMSSD from the verification component is sufficient to meet the stored degree of reduction in the SDNN or RMSSD during actual smoking, the controller may maintain the control state of the first stimulation unit 121, the second stimulation unit 122, and / or the third stimulation unit 123. On the other hand, if the degree of reduction in the SDNN or RMSSD from the verification component is not sufficient to meet the stored degree of reduction in the SDNN or RMSSD during actual smoking, the controller may increase or decrease the stimulation intensity of the first stimulation unit 121, the second stimulation unit 122, and / or the third stimulation unit 123.

[0115] In one embodiment, in the step of providing the electrical stimulation signal to the electrode, at least one of the frontal lobe, the parietal lobe, or the occipital lobe may be activated to increase beta waves.

[0116] Figure 12 is a block diagram of a smoking effect providing system 10 according to an embodiment.

[0117] refer to Figure 12 , the smoking effect providing system 10 may include a stimulation unit 12 (e.g., Figure 2The device includes a first stimulation unit 121, a second stimulation unit 122, or a third stimulation unit 123, and a controller 14. The stimulation unit 12 includes a stimulator for stimulating the user's brain. The controller 14 controls the stimulation signals of the stimulation unit 12. The controller 14 can control the stimulation unit 12 to reduce at least one of the delta wave or theta wave of the user's brain waves and increase the beta wave.

[0118] In one embodiment, the stimulation unit 12 may provide electrical stimulation to a location corresponding to the dorsal prefrontal cortex of the user.

[0119] In one embodiment, the smoking effect providing system 10 may further include a verification component 16 , which includes a verifier for verifying the smoking effect of the user, and the verification component 16 may transmit a smoking index signal measured from the user to the controller 14 .

[0120] In one embodiment, the controller 14 may determine the activity level of the stimulation unit 12 based on a user's smoking indicator (eg, heart rate variability index) signal received from the verification component 16 .

[0121] According to the wearable device 100 and the method for providing the smoking effect of one embodiment, the smoking effect can be provided to the user without smoking. In this case, the smoking effect can be effectively provided by stimulating the user's brain. According to one embodiment, the wearable device 100 and the method for providing the smoking effect can maximize the awakening effect by distinguishing the stimulation site according to the brain waves of the user O. According to one embodiment, the wearable device 100 and the method for providing the smoking effect can adjust the stimulation activity according to the user's feedback (for example, the user's heart rate variability), thereby effectively controlling the degree of brain stimulation.
