The base portion has a first fastener in the form of a full ring integral to the housing and defining a through-hole. The head portion has a second fastener in the form of an open ring integral to the housing and defining a snappable recess. The device includes a frequency generator housed in the housing and electrically connected to an electrode pair disposed on the housing, for applying a voltage with at least two different frequencies between the electrodes. ## Claims ### Claim 1 A fastenable device comprising: a housing comprising a base portion, a head portion opposite to the base portion, and a body portion between the base portion and the head portion, wherein the base portion comprises a first fastener in the form of a full ring integral to the housing and defining a through-hole, and wherein the head portion comprises a second fastener in the form of an open ring integral to the housing and defining a snappable recess; a frequency generator housed in the housing and electrically connected to an electrode pair disposed on the housing, for applying a voltage with at least two different frequencies between the electrodes; an accelerometer providing accelerometer data; an impedance-measure unit in communication with the electrode pair and providing impedance-measurement data; and a wireless transmitter in communication with the accelerometer and the impedance measure unit. ### Claim 2 (depends on 1) The device of claim 1, further comprising an electrical source electrically connected to the electrode pair to form an impedance between the electrodes when electrified. ### Claim 3 (depends on 2) The device of claim 2, wherein the head portion comprises a plurality of electrodes disposed thereon configured to form an impedance therebetween when electrified. ### Claim 4 (depends on 3) The device of claim 3, wherein the plurality of electrodes comprises at least four electrode pairs. ### Claim 5 (depends on 1) The device of claim 1, wherein the head portion comprises a plurality of electrodes disposed thereon and configured to form an impedance therebetween when electrified. ### Claim 6 (depends on 5) The device of claim 5, wherein the plurality of electrodes comprises at least four electrode pairs. ### Claim 7 (depends on 1) A method of fastening a fastenable device to a toothbrush neck, comprising the steps: (a) providing the fastenable device according to claim 1; (b) providing a toothbrush comprising a handle portion and an opposing bristle head, with the neck portion being disposed between the handle portion and the bristle portion; (c) sliding the bristle head through the through-hole of the first fastener until the handle portion abuts the first fastener; and (d) squeezing the head portion or the body portion and the toothbrush neck portion together until the snappable recess snaps around at least a portion of the toothbrush neck thereby fastening the fastenable device to the toothbrush neck. ### Claim 8 A fastenable device comprising: a housing comprising a base portion, an opposing head portion, and a body portion therebetween, wherein the base portion includes a first fastener comprising a first open ring integral to the housing and defining a first snappable recess, wherein the head portion includes a second fastener comprising a second open ring integral to the housing and defining a second snappable recess; a frequency generator housed in the housing and electrically connected to an electrode pair disposed on the housing for applying a voltage with at least two different frequencies between the electrodes; an accelerometer providing accelerometer data; an impedance-measure unit in communication with the electrode pair and providing impedance-measurement data; and a wireless transmitter in communication with the accelerometer and the impedance-measure unit. ### Claim 9 (depends on 8) The device of claim 8, further comprising an electrical source electrically connecting to the electrode pair to form an impedance between the electrodes when electrified. ### Claim 10 (depends on 9) The device of claim 9, wherein the head portion comprises a plurality of electrodes disposed thereon and configured to form an impedance therebetween when electrified. ### Claim 11 (depends on 10) The device of claim 10, wherein the plurality of electrodes comprise at least four electrode pairs. ### Claim 12 (depends on 8) The device of claim 8, wherein the head portion comprises a plurality of electrodes disposed thereon and configured to form an impedance therebetween when electrified. ### Claim 13 (depends on 12) The device of claim 12, wherein the plurality of electrodes comprises at least four electrode pairs.
